On the Internet found an article on how to remake the car generator to the generator with permanent magnets. Is it possible to use this principle and remake the generator with your own hands from an asynchronous electric motor? It is possible that there will be large energy losses, not the location of the coils.

Asynchronous type, I have a 110 volt voltage, turns - 1450, 2.2 amps, single-phase. With the help of tanks, I do not take the homemade generator, as there will be large losses.

It is proposed to use simple engines according to such a scheme.

We make a generator from an asynchronous electric motor on their own at home

If you change the engine or generator with a rounded form magnets from speakers, then you need to install them in crabs? Crabs are two metal parts, anchored outside the excitation coils.

If the magnets wear on the shaft, the shaft will shunt the magnetic power lines. How will the excitement be? The coil is also located on the shaft of metal.

If you change the connection of the windings and make a parallel connection, dispersed to revolutions above normal values, then it turns out 70 volts. Where to get a mechanism for such revolutions? If you rewind it on the reduction of revolutions and below the power, then the power drops too.

An asynchronous type engine with a closed rotor is an iron that is polished by aluminum. You can take a homemade generator from the car, in which the voltage is 14 volts, the current is 80 amp. This is good data. The engine with a collector on alternating current from the vacuum cleaner or washing machine can be applied to the generator. Install the stator to establish a constant current voltage to shoot with brushes. By the greatest EDC change the angle of brushes. The efficiency is striving for zero. But, it is better than a synchronous type generator, not invented.

I decided to experience the homemade generator. Single-phase asynchronous motor from the baby's washing drill. I connected a capacity of 4 μF to it, it turned out 5 volts of 30 hertz and a current of 1.5 milliam per short circuit.

Not every electric motor can be used as a generator in this method. There are motors with a steel rotor, having a small degree of magnetization on the residue.

It is necessary to know the difference between the transformation of electrical energy and generation of energy. Convert 1 phase to 3 in several ways. One of them is mechanical energy. If the power station is disconnected from the outlet, then all transformation disappears.

Where does the movement of the wire with an increase in speed, clearly. From where the magnetic field will be to obtain EDC in the wire - it is not clear.

Explain it just. Because of the mechanism of magnetism, which remained, the EMF is formed in anchor. There is a current in the stator winding, which is closed on the tank.

The current arose, which means that it gives an increase in the electromotive force on the coils of the rotor shaft. The current current gives an increase in the electromotive force. Stator electrotox forms electromotive force much more. It goes until the equilibrium of stator magnetic streams and rotor, as well as additional losses.

The size of the capacitors is calculated in such a way that at the outputs, the voltage reaches the nominal value. If it is small, then reduce the container, then increase. There were doubts about old engines that are allegedly excited. After overclocking the rotor of the motor or generator, it is necessary to poke quickly to any phase with a small amount of volts. Everything will come to a normal state. Charge a capacitor to a voltage of equal half of the tank. Turning on with a switcher with three poles. This applies with a 3-phase motor. Such a scheme is used for passenger transport cars generators, as they have a short-circuited rotor.

Method 2

A homemade generator can be done differently. The stator has a tricky design (has a special design solution), it is possible to adjust the output voltage. I made a generator with my own hands of this kind on construction. The engine took 7 kW with a capacity of 900 revolutions. I connected an excitation winding by a triangle scheme to 220 V. launched it to 1600 revolutions, the capacitors were 3 to 120 μF. They included the contactor with three poles. The generator acted as a rectifier with three phases. From this rectifier, an electric drill was fed with a collector for 1000 watts, and a 2200 watt disc chopped, 220 V, Bulgarian 2000 watt.

I had to make a soft start system, another resistor with a short phase after 3 seconds.

For motors with collectors it is incorrect. If you increase the rotating frequency in two times, the container will decrease.

The frequency will also increase. The containers circuit turned off in automatic mode so as not to use the reactivity torus, do not spend fuel.

During operation, you need to click on the stator of the contactor. Three phases disassemble them by unnecessariness. The reason lies in a high gap and an enlarged scattering of the pole field.

Special mechanisms with a double cell for protein and oblique eyes for a protein. Still, I got from the Motorker washing 100 volts and the frequency of 30 hertz, the lamp on 15 watts does not want to burn. Very weak power. It is necessary to take a motor stronger, or more capacitors.

Under the wagons, a generator with a rotor is short-circuited. Its mechanism comes from the gearbox and on the belt transmission. Rotation speed 300 revolutions. It is like an additional load generator.

Method 3.

You can construct a homemade generator, a power station on gasoline.

We make a generator from an asynchronous electric motor on their own at home

Instead of a generator, use a 3-phase asynchronous motor for 1.5 kW per 900 revolutions. Italian electric motor, can be connected triangle and star. At first I put the engine on the base with the DC motor, attached to the coupling. Began to turn the engine at 1100 revolutions. A voltage 250 volts appeared on the phases. I connected a 1000 watt light bulb, the voltage immediately fell to 150 volts. Probably, it is from phase skew. For each phase, it is necessary to include a separate load. Three 300 watt bulbs will not be able to reduce the voltage up to 200 volts, theoretically. You can put a capacitor more.

Engine turnover must be done more, when loading does not reduce, then the nutrition network will be permanent.

Significant power is necessary, the autogenerator will not give such power. If you rewind a large KAMAZ, then 220 V will be released from it, since the magnetic core will be oversaturated. It was designed for 24 volts.

Today I was going to try to connect the load through a 3-phase power supply unit (rectifier). In the garages, the light turned off, failed. In the city of power engineers systematically turn off the light, so it is necessary to make a source of constant power to electricity. For electric welding there is a hitch, shaped to the tractor. To connect an electrical tool, a permanent voltage source is needed to 220.. There was a thought to construct the homemade generator with your own hands, and the inverter to it, but, on batteries, it is not long to work.

Recently included electricity. Connected an asynchronous engine from Italy. Put it with a motor chainsaws on the frame, twisted the shafts together, put the rubber clutch. The coils connected according to the stars scheme, triangle condensers, 15 μF. When the motors launched, it did not work at the power output. Attached the capacitor charged to phases, the voltage appeared. The engine issued its capacity of 1.5 kW. In this case, the supply voltage decreased to 240 volts, 255 volts were at idle. Schlifmashinka normally worked for 950 watts.

I tried to increase engine speed, but it fails. After contacting the capacitor with a phase, the voltage occurs immediately. I will try to put another engine.

What designs of systems abroad are made for power plants? On 1-phase it is clear that the rotor owns winding, no phase skew, because one phase. In 3-phase there is a system that gives power adjustment when connected to it with the highest load. You can still connect an inverter for welding.

On the weekend I wanted to make a homemade generator with my own hands with the connection of an asynchronous engine. A successful attempt to make a homemade generator was to connect an old engine with a cast iron case per 1 kW and 950 revolutions. The motor is excited normally, with one capacity of 40 μF. And I installed three containers and connected them with a star. It was enough to launch the electric drill, the grinder. I wanted to give out the issuance of voltage at the same phase. For this, the three diodes connected, half-lit. Luminescent lamps are burned down for lighting, and burned packets in the garage. I will appreciate the transformer into three phases.

Write comments, additions to the article, maybe I missed something. Ploy on Map of the site electronics I will be glad if you find on my site. something more useful. Share information in social networks, put like, if you like it - it will help the development of the channel

What are the generators and where apply

Autonomous power plant - this equipment can produce electricity due to fuel combustion. They are both single and three-phase. Moreover, the latter are distinguished by the possibility of working with various loads.

They are used as a backup and in some cases a permanent source of power supply and are intended for operation:

  • At dachas and in cottages;
  • Exhibition and trading pavilions;
  • Construction sites;
  • Recreational camps;
  • Small towns.

Device and principle of operation

The machine capable of converting mechanical energy into electrical is called a power unit. Its principle of operation is based on a well-known person from the course of school physics phenomenon of electromagnetic induction.

It says that in the conductor moving in a magnetic field and intersecting the power lines is formed by EMC. Therefore, it can be considered as a source of electricity.

But since this method is not entirely convenient for practical application, it changed it in the generators using the rotational motion of the conductor. In theoretical terms, power plants are a system of electromagnets and conductors. But in constructive, they consist of internal combustion engines and generators.

Operating principle

By definition, the generator is a device that converts mechanical energy into an electric current. It does not matter what energy is used to rotate the rotor: the wind, potential energy of water, or internal energy transformed by the turbine or the engine to mechanical.

As a result of rotation of the rotor, magnetic power lines formed by the residual magnetization of steel plates are crossed by the stator winding. EMF is formed in the coils, which, when connecting active loads, leads to the formation of the current in their circuits.

It is important that the synchronous speed of rotation of the shaft slightly (about 2 to 10%) exceeded the synchronous frequency of the AC (set by the number of poles of the stator). In other words, it is necessary to ensure asynchrony (mismatch) of the rotational speed on the magnitude of the sliding of the rotor.

It should be noted that the current thus obtained will be small. To increase the output power, it is necessary to increase the magnetic induction. Protecting the efficiency of the device by connecting capacitors to the conclusions of the stator coils.

The figure shows the scheme of a welding asynchronous alternator with condenser excitation (left part of the circuit). Note that the excitation condensers are connected according to the triangle scheme. The right side of the pattern is the actual scheme of the inverter welding machine itself.

There are other, more complex excitation schemes, for example, using inductance coils and capacitor batteries. An example of such a schema is shown in the figure.

Asynchronous generator: features and advantages

By the type of rotation of the rotor generators are synchronous and asynchronous . The first have a complex design, as well as more sensitive to voltage drops on the network, which affects their productivity. Asynchronous, on the contrary, possess a simpler principle of action, and also have excellent specifications.

Magnetic coils are placed on the rotor of the synchronous generator, which complicates the rotor movement process, while the asynchronous generator rotor is rather similar to the usual flywheel. Constructive features significantly affect the efficiency, and in synchronous there is its loss (up to 11%). In an asynchronous energy loss rate decreases to 5%, which makes it more popular not only in everyday life, but also in production.

There are also others Advantages of asynchronous generators :

  1. A simpler body protects the engine from moisture and exhaust fuel, reducing the need for frequent maintenance.
  2. The generator is resistant to voltage drops, and also has a rectifier at the output that protects the connected electrical appliances from the breakage.
  3. The device is able to serve as a power source for devices that have an ohmic load and high sensitivity to voltage jumps: welding machines, computer and computing equipment, incandescent lamps.
  4. It has high efficiency, which is combined with a minimum clearing (energy loss indicator, which is spent on the heating of the device itself).
  5. There is no service life for at least 15 years, since all parts used are sufficiently reliable and is not amenable to rapid wear during operation.

Technological features

The basis of the self-made generator is an asynchronous three-phase current electric motor with:

  • phase;
  • or short-circuited rotor.

Stator device

The magnetic pipelines of the stator and the rotor are made of electrical steel plates, in which the grooves are created to place the winding wires. The individual stator windings can be connected to the factory according to the scheme:

  • stars;
  • or triangle.

Their conclusions are connected inside the terminal box and are connected by jumpers. This is the same as a power cable. In some cases, the wires and cable can be connected in other methods. For each phase of an asynchronous motor, symmetrical voltages are mounted, shifted across the corner by a third of the circle. They form currents in windings.

Forms of the sinusoid of voltages and currents in the asynchronous engine

These values ​​are conveniently expressed in vector form.

Designations on the engine housing

Specifications can be found on a plate that is placed in a prominent place. An example of its design and decoding designations are shown in photos. The homemade generator worked reliably to pay attention to:

  • IP class characterizing the quality of the body protection from the effects of the external environment;
  • power consumption;
  • speed;
  • scheme connection windings;
  • permissible load currents;
  • Efficiency and cosine φ.

The scheme of the connection of the windings, especially in old engines, former in the work, should be called, check with electrical methods. This technology is described in detail in the article on connecting a three-phase motor into a single-phase network.

The principle of operation of an asynchronous motor as a generator

The basis of its incarnation laid the method of reversibility of the electric car. If the engine is disconnected from the voltage from the voltage to begin forcibly rotating the rotor at the estimated speed, the EDC will be guided in the stator winding due to the presence of the residual energy of the magnetic field.

It remains only to connect to the windings a condenser battery of the corresponding nominal and it will be a capacitive advanced current, having a magnetizing character.

So that the generator self-exclusion occurred, and the symmetric system of three-phase stresses was formed on the windings, it is necessary to select the capacitance of capacitors greater than a certain, critical value. In addition to its value to the output power, naturally, the engine design affects.

For the normal generation of three-phase energy with a frequency of 50 Hz, it is necessary to maintain the rotation speed of the rotor exceeding the asynchronous component by the magnitude of the slide S, which lies in the limits of S = 2 ÷ 10%. It is required to maintain at the synchronous frequency level.

The waste of sinusoids from the standard value in the frequency will adversely affect the equipment with electric motors: saw, plates, various machines and transformers. On resistive loads with TEN and incandescent lamps, it practically does not affect.

Difference from a synchronous generator

The main difference between the synchronous alternator from the asynchronous generator in the rotor design. In the simultaneous machine, the rotor consists of wire windings. To create magnetic induction, an autonomous power supply is used (often an additional low-power DC generator located on a single axis with a rotor).

The advantage of the synchronous generator is that it generates a better current and easily synchronized with other alternators of this type. However, synchronous alternators are more sensitive to overloads and KZ. They are more expensive from their asynchronous fellow and demanding more in service - it is necessary to monitor the condition of the brushes.

The harmonic coefficient or an asynchronous generator clearing is lower than that of synchronous alternator. That is, they produce practically clean electricity. There are more stable on such currents:

  • UPS;
  • adjustable chargers;
  • Modern television receivers.

Asynchronous generators provide confident launch of electric motors requiring large starting currents. According to this indicator, they are actually not inferior to synchronous machines. They have less jet loads, which has a positive effect on thermal mode, as less energy is spent on reactive power. Asynchronous alternator has the best stability of the output frequency at different speeds of rotation of the rotor.

Operating tips

Before making a household electricity generator, you need to familiarize yourself with the rules of its operation. Their essence is as follows:

  1. Before starting the device, all loads are disconnected so that it will work well.
  2. The presence of oil in the operating compartment of the generator is checked - its level must be higher than the set mark;
  3. The device remains on about 5 minutes, after which it is allowed to connect the load.

In accordance with the rules of operation and care for such generators, the most suitable mode of work is considered to use its capacity by 70% of the limit value. If this requirement is compliance, the equipment will not overheat and easily cope with the calculated load.

Application area

The most commonly applying generator sets with a short-circuited rotor is most common. They are inexpensive, practically do not need maintenance. Devices equipped with trigger capacitors, have decent indicators of the efficiency.

Asynchronous alternators are often used as an autonomous or backup power source. Portable petrol generators work with them, they are used for powerful mobile and stationary diesel generators.

Three-phase winding alternates confidently start a three-phase electric motor, so often used in industrial power plants. They can also feed equipment in single-phase networks. The two-phase mode allows you to save fuel in the DVS, since unused windings are in idle mode.

The scope of application is quite extensive:

  • transport industry;
  • Agriculture;
  • Household sphere;
  • medical institutions;

Asynchronous alternators are convenient for the construction of local wind and hydraulic power plants.

Classification

There are two types of DC generators:

  • with independent excitation of windings;
  • With self-excitation.

For self-excitation of generators, electricity produced by the device itself is used. On the principle of connecting windings, self-excited alternators with are divided into types:

  • Devices with parallel excitation;
  • Alternators with consistent excitation;
  • Mixed type devices (compound generators).

Consider in more detail the features of each type of junction of the anchor windings.

With parallel excitation

To ensure normal operation of electrical appliances, the presence of a stable voltage at the clamps of generators, independent of changes in the total load, is required. The task is solved by adjusting the excitation parameters. In alternately with parallel excitation, the conclusions of the coil are connected via the adjusting retail parallel to an anchor winding.

The excitation rheostats may close the winding "on themselves". If this is not done, then when the excitation chain is breaking, the emf of self-induction will increase dramatically, which can break the insulation. In a state corresponding to the short circuit, the energy is dissipated in the form of heat, preventing the destruction of the generator.

Electrical machines with parallel excitation do not need an external power source. Due to the presence of residual magnetism, there is always a self-excitation of parallel windings present in the electromagnet core. To increase the residual magnetism in the excitation coils, the cores of electromagnets are made from cast steel.

The process of self-excitation continues until the moment until the current reaches its limiting value, and the EMF will not reach the nominal indicators with the optimal turnover of rotation of the anchor.

With independent excitation

Batteries or other external devices are often used as a power source for excitation windings. In models of low-power machines, constant magnets are used, which provide the presence of the main magnetic flux.

The power generator is located on the shaft of powerful generators, generating a permanent current to excite the main anchor windings. For excitation, it is enough to 1 - 3% of the nominal anchor current and does not depend on it. Changing EMF is carried out by adjusting retake.

The advantage of independent excitement is that the voltage on the clips does not affect the excitation current. And this ensures good external characteristics of the alternator.

With consistent excitation

Serial windings produce current, equal to the current of the generator. Since idling the load is zero, then the excitation is zero. This means that the characteristic of idling cannot be removed, that is, there are no adjusting characteristics.

In generators with consistent excitation, there is practically no current when rotating the rotor at idle. To start the excitation process, you must connect the external load to the generator clamps. Such a pronounced voltage dependence of the load is disadvantage of serial windings. Such devices can only be used to power electrical appliances with constant load.

With mixed excitation

Useful characteristics combine the design of generators with mixed excitation. Their features: devices have two coils - the main, connected parallel winding windings and auxiliary, which is connected sequentially. The parallel winding circuit includes a retainer used to adjust the excitation current.

The process of self-excitation of an alternator with mixed excitation is similar to that which has a generator with parallel windings (due to the lack of initial current, the sequential winding in self-excitation does not participate). The characteristic of idling is the same as an alternator with a parallel winding. This allows you to adjust the voltages on the generator clamps.

Mixed excitation smoothes the tension pulsation at a rated load. This is the main advantage of such alternator before other types of generators. The disadvantage is the complexity of the design, which leads to the rise in prices for these devices. Do not suffer such generators and short circuits.

Do or buy?

Electric generator with your own hands

The desire to have an electric generator in its use is overshadowed by one nuisance - this is in

The cost of the aggregate

. No matter how cool, but the most low-power models have a fairly transcendent cost - from 15,000 rubles and higher. It is this fact that comes to the idea of ​​his own creation of the generator. However, Sam

the process can be difficult

, if a:

  • no skill in working with tools and schemes;
  • There is no experience in creating such devices;
  • There is no need for the necessary parts and spare parts.

If all this and a huge desire are present, then You can try to collect generator , guided by the assembly instructions and the attached scheme.

It is no secret that the purchase of the electric generator will have a more advanced list of features and functions, while homemade is able to bring and malfunctions to the most inappropriate moments. Therefore, buy or do it yourself - the question is purely individual, requiring a responsible approach.

Methods of manufacture

There are many master classes dedicated to how to do it right and what is better. It should be understood that the generator needs uninterrupted meals for the implementation of constant rotation and generating electricity. For this, another engine is suitable.

You can also use wind energy by constructing the generator so that you can push the blades to the anchor, which will rotate.

The easiest way is to remake an asynchronous single-phase motor into a DC generator using one of 3 ways:

We make a parallel connection of the excitation windings (on the star). Next are needed, which are higher than normal to produce current at the output. It will appear in the stator windings. You can remove it through the collector rings. For uninterrupted power supply, you can use the engine from the washing, vacuum cleaner or drill.

Tools and materials

A suitable engine is taken as the operating module of an electromagnetic (mechanical) generator. Multi-type engines are used: collector (brush), uncoolette, stepper (brushes and rings are not used), synchronous and asynchronous. Depending on which current is generated, the following parts and nodes apply.

  • Rectaging diodes. Convert alternating current to permanent. There are high-power diode bridges, designed for current in dozens of amps and voltage up to 50 V.
  • Polar capacitors . Designed for permanent current. Play the role of smoothing filter, leveling constant voltage ripples.
  • Extra charge with USB port - converts a voltage of 1.5-20 volts to the necessary smartphones, tablets and most laptops 5. Books on Aliexpress.com and in other online stores.

All these radio components are needed when the motor generator gives no more than a pair of dozens volts.

Using, for example, an asynchronous engine will require the connection of your gadgets and other devices in normal mode - both from the household outlet.

Auxiliary materials can be anyhow, as they play the role of the supporting structure:

  • wooden bars;
  • Metal fittings;
  • profiles;
  • Fastening compounds (bolts with nuts and washers, clamps, brackets, clamps, brackets, screws);
  • pipes of any diameter, etc.

The following products apply as power tools.

  • Bulgarian With a set of cutting discs (for metal and wood) and grinding (comes in the form of an eattered circle or a universal solid disk).
  • Electric drill With a set, rolled metal. If it is installed, for example, a wind generator with a support on the wall of the house, it may be necessary to take a standard perforator with a set of drum drums and / or concrete crowns. The perforator can also be equipped with an adapter for simple or tapered rods and crowns on wood.
  • Sculpture. It will be necessary when the design is massive, and screw the screws in an amount from several tens. It can be completed with the heads under the adapter-wrench or universal head under the nut, resembling an adjustable key.

Prepare the desired inventory, proceed to the process of manufacturing the generator set.

Assembly scheme

The asynchronous generator has the property of self-synchronization: the inclusion of a rotor winding in operation without meals, in which a constant magnetic field is excited. Self-excitation of the winding of a short-circuited rotor is made due to the phenomenon of residual magnetization. To assemble an asynchronous generator, follow the instructions below.

  1. Place the engine and transmitter on one carrier design.
  2. Connect to windings Variables (non-polar) capacitors . The windings themselves are included according to the "Star" scheme: some ends are converged in the center (on the body), the others are derived separately.
  3. Capacitors are connected according to the "Triangle" scheme: free ends of the windings are connected to its vertices. . Engine power - 2-5 kilowatt, capacitance capacitors - 28-138 microfrades. Pick up such a container so that the voltage generated does not decrease - depending on the load, which is planned to be used.

Before starting the generator, make it testing. The test can be performed using a conventional incandescent bulb for several dozen watts. The task is to ensure the uninterrupted issuance of the produced voltage. This will require an installation capable of issuing 3000 revolutions per minute. For example, a powerful windmill with a gearbox (or chain drive), a fuel engine from any unit, hydroturbine on the river, etc.

The fact is that a person alone will not be able to unwind any motor generator into power over 150 W, whatever efforts fit. Here it is limited.

The manufacture of an asynchronous generator is the simplest alteration of the scheme of the finished engine. The rotor flows for neodymium magnets are not required, which you can not say about the car generator, in which the power of the rotor winding is made from the battery. By the way, most modern automotive generators are based on a synchronous motor in which the speed of revolutions is rigidly connected with the frequency of the current produced. To get rid of the need to feed the rotor winding, you can redo the engine, removing this winding and overshable the axis of the rotor under flat magnets.

To assemble the generator on firewood, do the following.

  1. On the wall of the bourgeitry or pyrolysis furnace Place the "spikes" radiator inside.
  2. Mount On it one or more elements of Peltier, focusing on the radiator area.
  3. Attach to the element Peltier is another radiator.
  4. Position the installation on the shadow side of the house in a specially reserved place. The wall should not have insulation, as well as be too thick at this point, as you need access to street cold. The ideal option is the technical room compartment for such a stove, in which there is a retrach vents for burning firewood. The radiator is located next to it from the cold side.

The launch of such a generator is carried out during the ignition of firewood. When the firewood spars, the Peltier element will give maximum power. It will be cooled with cold air setting from the street. The process of heating will provide the wall of the stove.

To build a collector generator, it is recommended to use the following instruction.

  1. Place the collector motor on the carrier frame or another design.
  2. Configure the DC smoothing capacitor and the converter board (DC inverter) to its outputs.
  3. Connect the USB port to the DC-card output (if it is not equipped with it).
  4. Position the generator on the bike frame either make a "windmill" for it (for example, from the parts from the fan with the failed engine). In the latter case, for the convenience of the "windmill" there is a vane-shank, turning the design to the other side where the wind blows.

Connect your smartphone, tablet, mobile phone, smart clock or other device. The motor from the printer, for example, produces up to several watts of power: so, at 12 volts, which it is designed, the current can reach 600 milliam. Disadvantages of collector engines: Low efficiency and frequent replacement of brushes.

Working every day for several hours, the brushes will serve as a maximum of 2-3 months.

Instead of the collector electric motor, use stepper: its efficiency is significantly higher, it is able to serve not one ten years. In online stores, full models giving voltage at 12 volts and a current of 1.8-4.2 amps. The windings at the stepper motor can be 2, 3 or 4. When turning them in consistently, you will receive 24, 36 or 48 V. Parallel inclusion. Dast is proportionally more amperezh. "To dispersed" the generator to the desired voltage rating will be more difficult.

Operating recommendations

The generator used in the street conditions (wind power station for a private house, cyclenener) is recommended to be protected from rain, road dirt and other extraneous particles by placing it in a separate case.

A device that works in street conditions in the multi-hour daily load mode needs regular (at least half a year) lubrication of bearings. They, in turn, are in each motor generator.

Shooting of the engine and auxiliary electronics is not allowed. The closed engine is promoted several times more difficult at the expense of the rotation of the power rotor, proportional load. Winding, closed in short with a spinning shaft, can burn. Semiconductor electronics (solar panels, Peltier elements) also fails, being closed.

Vertical windmaster electric current generator

Make your own hands a wind device with a vertical axis of rotation is easy. It is enough to buy mandatory components of details, collect them correctly and install the unit to the selected place.

For the manufacture of a wind device, the following materials will be required:

  • The axial mast is the supporting structure in the form of a pyramid having a height of 5 meters. It is fixed by the generator and blades.
  • Blades catch wind streams.
  • The stator includes phases from coils.
  • The rotor is the moving part of the windmill.
  • The controller slows down the device when he develops greater power.
  • The inverter displays an alternating current, and the battery accumulates energy.

For the manufacture of blades, high-quality plastic will be required. Even plastic pipes are suitable. In this case, tin fragments are fixed to each side of the pipe.

For the rotor, two ferrite disks will be required, the diameter of which is 32 cm. For the stator, nine coils with 60 copper coils should be made.

The form for coils needs to be made of plywood and lay out fiberglass.

Collect a wind generator is needed as follows:

  • From above in the rotor to do a hole for the stud.
  • In the stator to do the holes to secure to the stand.
  • To lay the bottom disk of the rotor on the stand of the magnets upstairs.
  • Here to install the stator and fasten with studs in the plate.
  • Cover the design by another disk.
  • Using the rotation of the studs, it is necessary to achieve a uniform approach of the upper and lower disks, after which the studs with a plate carefully remove.
  • Secure the generator nuts.
  • Finished device fasten to axial mast.

Electricity launches Lastly: Energy from the device falls on the controller, then it is collected on the battery and turns into an alternating current inverter.

The vertical generator turns the wind into the energy resource. For good work, he does not need additional devices that determine the direction of the wind.

It does not require devices that ensure safe repair work.

Useful! The minimum number of moving parts make such an installation reliable and sustainable.

The device works without noise, does not interfere with the neighbors and owners, does not forms harmful emissions into the atmosphere and reliably serves for many years.

Water generator 220 V: How to do at home?

For the heating of private houses, different methods are used. They differ from the transmission of heat and the type of energy. During the use of water heating, different types of boilers are applied depending on the type of fuel:

  • Solid fuel - in this case, solid fuel is used for operation.
  • Electric - in such boilers, heat is converted by conversion of electricity.
  • Gas - in such heat pumping boilers occurs at the time of gas combustion.

The water generator is a water container in which the electrodes for the conversion of water into oxygen and hydrogen are located. To make an independently water generator, you will need:

  • stainless steel sheet;
  • Plate of plexiglass;
  • Rubber tubes for water supply and gas removal;
  • rubber sheets;
  • The voltage source that should ensure the flow of current in 5-8 A.

Water electric generator

To assemble a water generator, it is necessary:

  • First cut the stainless plates on rectangular sheets.
  • Corners to cut on them to pull the device to bolts.
  • In each plate, drill a hole in 5 mm at a distance of 3 cm from the bottom of the plate for receipt and removal of water.
  • In addition, the Wire should be soldered to the plates to attach it to the power source.

Before collecting a rubber generator, first cut rings with a diameter of 200 × 190 mm. Two plates are prepared from plexiglass with dimensions of 200 × 200 mm, while you need to drill holes in them to all sides under the M8 bolts.

Collect the water generator starts like this: first put the first plate, then the rubber ring, a sealant missing, and so on according to the same scheme. After that, the entire design is tightened by bolts and plates of plexiglass.

In the latter you need to drill holes: in one plate below, the liquid passed into the other - at the top for the gas removal. There you should insert a fitting. Polychlorvinyl tubes should be put on these fittings.

Reference! So that the gas does not come back to the gas generator, on the way from it to the burner you need to install a water shutter.

Of the advantages of this type of heating, the following are distinguished:

  • Ecological type of heating, because when combustion of hydrogen in oxygen, water appears in the form of a pair, and there are no emissions of harmful substances into the atmosphere;
  • You can not alone connect the generator to the already existing water heating system;
  • Installation works without noise, so it does not require some special room.

The disadvantages of the water generator include:

  • Hydrogen has a greater combustion temperature, so a simple boiler can quickly break.
  • While working with Brown gas, it is necessary to be careful because it is explosive.
  • When the water generator is working, the use of distilled water is necessary.

In fact, this is a micro power plant in your pocket. Take her hike and you will have a 100% source that will never discharge.

Need

It turns a plate and works from the network voltage. The view is a flat electric motor with a shifted from the center of the shaft - this is due to the gear built into it.

Asynchronous generator with his own hands

Let's notify immediately: it will not be about making a generator from scratch, but about the alternating an asynchronous engine in an alternator. Some craftsmen use the finished stator from the motor and experiment with the rotor. The idea is to make the Rotor Pole with the help of neodymium magnets. Approximately it may look like a blank with glitched magnets (see Fig. 6):

You stick the magnets on a specially sharpened blank planted on the motor shaft, observing their polarity and the shear angle. This will require at least 128 magnets.

The finished design must be adjusted to the Stator and at the same time provide a minimum gap between the teeth and the magnetic poles of the manufactured rotor. Since the magnets are flat, they will have to grind them or turn it out, while the construction is constantly cooling, since neodymium loses its magnetic properties at high temperatures. If you do everything right - the generator will earn.

The problem is that in handicraft conditions it is very difficult to make an ideal rotor. But if you have a lathe and you are ready to spend a few weeks for fitting and refinement - you can experiment.

I suggest a more practical option - turning an asynchronous engine to the generator (see the video below). To do this, you need an electric motor with a suitable power and an acceptable frequency of rotation of the rotor. The engine power must be at least 50% higher from the required power of the alternator. If such an electric motor is at your disposal - proceed to processing. Otherwise, it is better to buy a ready generator.

For processing, you will need 3 CBG-MN brand condenser, MBGO, MBGT (you can take other brands, but not electrolytic). Capacitors pick up at least 600 V voltage (for a three-phase engine). The reactive power of the generator q associated with the capacitor capacity of the following dependence: Q = 0.314 · U2 · C · 10-6.

With an increase in the load, reactive power increases, and therefore, to maintain a stable voltage U, it is necessary to increase the capacitors, adding new containers by switching.

Method 1

On the Internet found an article on how to remake the car generator to the generator with permanent magnets. Is it possible to use this principle and remake the generator with your own hands from an asynchronous electric motor? It is possible that there will be large energy losses, not the location of the coils.

Asynchronous type, I have a 110 volt voltage, turns - 1450, 2.2 amps, single-phase. With the help of tanks, I do not take the homemade generator, as there will be large losses.

It is proposed to use simple engines according to such a scheme. Homemade generator

If you change the engine or generator with a rounded form magnets from speakers, then you need to install them in crabs? Crabs are two metal parts, anchored outside the excitation coils.

If the magnets wear on the shaft, the shaft will shunt the magnetic power lines. How will the excitement be? The coil is also located on the shaft of metal.

If you change the connection of the windings and make a parallel connection, dispersed to revolutions above normal values, then it turns out 70 volts. Where to get a mechanism for such revolutions? If you rewind it on the reduction of revolutions and below the power, then the power drops too.

An asynchronous type engine with a closed rotor is an iron that is polished by aluminum. You can take a homemade generator from the car, in which the voltage is 14 volts, the current is 80 amp. This is good data. The engine with a collector on alternating current from the vacuum cleaner or washing machine can be applied to the generator. Install the stator to establish a constant current voltage to shoot with brushes. By the greatest EDC change the angle of brushes. The efficiency is striving for zero. But, it is better than a synchronous type generator, not invented.

I decided to experience the homemade generator. Single-phase asynchronous motor from the baby's washing drill. I connected a capacity of 4 μF to it, it turned out 5 volts of 30 hertz and a current of 1.5 milliam per short circuit.

Not every electric motor can be used as a generator in this method. There are motors with a steel rotor, having a small degree of magnetization on the residue.

It is necessary to know the difference between the transformation of electrical energy and generation of energy. Convert 1 phase to 3 in several ways. One of them is mechanical energy. If the power station is disconnected from the outlet, then all transformation disappears.

Where does the movement of the wire with an increase in speed, clearly. From where the magnetic field will be to obtain EDC in the wire - it is not clear.

Explain it just. Because of the mechanism of magnetism, which remained, the EMF is formed in anchor. There is a current in the stator winding, which is closed on the tank.

The current arose, which means that it gives an increase in the electromotive force on the coils of the rotor shaft. The current current gives an increase in the electromotive force. Stator electrotox forms electromotive force much more. It goes until the equilibrium of stator magnetic streams and rotor, as well as additional losses.

The size of the capacitors is calculated in such a way that at the outputs, the voltage reaches the nominal value. If it is small, then reduce the container, then increase. There were doubts about old engines that are allegedly excited. After overclocking the rotor of the motor or generator, it is necessary to poke quickly to any phase with a small amount of volts. Everything will come to a normal state. Charge a capacitor to a voltage of equal half of the tank. Turning on with a switcher with three poles. This applies with a 3-phase motor. Such a scheme is used for passenger transport cars generators, as they have a short-circuited rotor.

Method 2

A homemade generator can be done differently. The stator has a tricky design (has a special design solution), it is possible to adjust the output voltage. I made a generator with my own hands of this kind on construction. The engine took 7 kW with a capacity of 900 revolutions. I connected an excitation winding by a triangle scheme to 220 V. launched it to 1600 revolutions, the capacitors were 3 to 120 μF. They included the contactor with three poles. The generator acted as a rectifier with three phases. From this rectifier, an electric drill was fed with a collector for 1000 watts, and a 2200 watt disc chopped, 220 V, Bulgarian 2000 watt.

I had to make a soft start system, another resistor with a short phase after 3 seconds.

For motors with collectors it is incorrect. If you increase the rotating frequency in two times, the container will decrease.

The frequency will also increase. The containers circuit turned off in automatic mode so as not to use the reactivity torus, do not spend fuel.

During operation, you need to click on the stator of the contactor. Three phases disassemble them by unnecessariness. The reason lies in a high gap and an enlarged scattering of the pole field.

Special mechanisms with a double cell for protein and oblique eyes for a protein. Still, I got from the Motorker washing 100 volts and the frequency of 30 hertz, the lamp on 15 watts does not want to burn. Very weak power. It is necessary to take a motor stronger, or more capacitors.

Under the wagons, a generator with a rotor is short-circuited. Its mechanism comes from the gearbox and on the belt transmission. Rotation speed 300 revolutions. It is like an additional load generator.

Method 3.

You can construct a homemade generator, a power station on gasoline.

Instead of a generator, use a 3-phase asynchronous motor for 1.5 kW per 900 revolutions. Italian electric motor, can be connected triangle and star. At first I put the engine on the base with the DC motor, attached to the coupling. Began to turn the engine at 1100 revolutions. A voltage 250 volts appeared on the phases. I connected a 1000 watt light bulb, the voltage immediately fell to 150 volts. Probably, it is from phase skew. For each phase, it is necessary to include a separate load. Three 300 watt bulbs will not be able to reduce the voltage up to 200 volts, theoretically. You can put a capacitor more.

Engine turnover must be done more, when loading does not reduce, then the nutrition network will be permanent.

Significant power is necessary, the autogenerator will not give such power. If you rewind a large KAMAZ, then 220 V will be released from it, since the magnetic core will be oversaturated. It was designed for 24 volts.

Today I was going to try to connect the load through a 3-phase power supply unit (rectifier). In the garages, the light turned off, failed. In the city of power engineers systematically turn off the light, so it is necessary to make a source of constant power to electricity. For electric welding there is a hitch, shaped to the tractor. To connect an electrical tool, a permanent voltage source is needed to 220.. There was a thought to construct the homemade generator with your own hands, and the inverter to it, but, on batteries, it is not long to work.

Recently included electricity. Connected an asynchronous engine from Italy. Put it with a motor chainsaws on the frame, twisted the shafts together, put the rubber clutch. The coils connected according to the stars scheme, triangle condensers, 15 μF. When the motors launched, it did not work at the power output. Attached the capacitor charged to phases, the voltage appeared. The engine issued its capacity of 1.5 kW. In this case, the supply voltage decreased to 240 volts, 255 volts were at idle. Schlifmashinka normally worked for 950 watts.

I tried to increase engine speed, but it fails. After contacting the capacitor with a phase, the voltage occurs immediately. I will try to put another engine.

What designs of systems abroad are made for power plants? On 1-phase it is clear that the rotor owns winding, no phase skew, because one phase. In 3-phase there is a system that gives power adjustment when connected to it with the highest load. You can still connect an inverter for welding.

On the weekend I wanted to make a homemade generator with my own hands with the connection of an asynchronous engine. A successful attempt to make a homemade generator was to connect an old engine with a cast iron case per 1 kW and 950 revolutions. The motor is excited normally, with one capacity of 40 μF. And I installed three containers and connected them with a star. It was enough to launch the electric drill, the grinder. I wanted to give out the issuance of voltage at the same phase. For this, the three diodes connected, half-lit. Luminescent lamps are burned down for lighting, and burned packets in the garage. I will appreciate the transformer into three phases.

Write comments, additions to the article, maybe I missed something. Take a look at the site map, I will be glad if you find something more useful on my site.

Homemade generator 220 V using a 2-stroke engine

Stage first: fix the engine from the motocos

For a start, we take a segment of the board and cut it pre-in the size of our bed. It is advisable to take a weighty material so that our equipment has a durable and reliable base. Watch the position of the engine from the motocos. With the help of a paper template, there are accurate holes, picking them up with a drill or screwdriver. Similarly, both engines on the bed. We disconnect the fuel tank, and fasten the engine from the motocos.

Stage Second: Fresh DC Machine

Location the position of the engine. The distance from both shafts of engines should be a few centimeters to avoid friction between them.

How to make a generator on 220 V

Center the shafts of our engines. The discrepancy in the centers is the easiest way to be adjusted by any gaskets, or simply adjust the seat on a wooden bed. You can make it a regular chisel. The smaller the backlash is between the shafts, the smaller the vibration from the unit and the wear of the driving part.

Place the nozzles. Most often, the shafts of the engines differ in size of diameters. It is also fixable if the hoses of different diameters are used as connecting pipes. Their flexibility will help smooth the smallest inaccuracy in the center of the shafts. In our case, the author used two hoses of different diameters by inserting one in another

I cut off the nozzles of the length of the length, sit on both sides three clamps, pressing them with a screwdriver.

We fix the DC motor on the self-tapping screw, having paved them before washers. Trees connect from hand and press the clamp with a screwdriver.

Now you can fix the fuel tank. It is not difficult to cope with this task using a long self-tapping screw and a cropped cap from a dowel-nail. Do not forget to connect fuel tubes.

Playing the fuel engine starter, measure the voltage at the outlet voltmeter. By screwdriver adjust the supply of fuel, and the number of revolutions from which the voltage depends on. Focusing on the nominal inverter, set the outgoing stress with a small margin.

Stage Third: Connect the inverter

Stripped pre-ends of cables from a DC motor fix on the terminals of the inverter. The power indicator will immediately show the activity of the device. Examined control (light bulb with a segment of the cable and fork at the end) check the operation of our miracle generator.

To connect the electric motor to the inverter, use the terminals.

Stage Fourth: Engine Turning Off button

Since the engine leads the engine that creates mechanical rotation, it needs a switch. The off button is complete with the device, so it only needs to find a comfortable place.

How to make a generator on 220 V

Stage Fifth: Make a Cover Frame

We make a protective frame from polypropylene pipes with a diameter of 25-32mm, making the hole in the hole with a feathery drill.

At the corners we connect it with the help of polypropylene fittings.

If there is no plumbing welding machine, the design can be connected to specialized glue for PP pipes.

This frame will also help in carrying the device.

Well, and to eliminate the noise from the vibration of our device, you can secure 4 scales on the back of the bed, making them as shown in the photo, from segments of an old bike camera.

Stage Six: Starting Battery

To once again not pull the fuel engine starter, the videos applied a lithium-polymer battery (Lipo) for short-term DC motor. This comparative new device can really be powerful, and to withstand a large number of working cycles with minimal loss of capacitive power. Thus, the fuel engine starts electrically, while its starter remains as a backup option.

We connect the overcoming batteries to the inverter terminals through the starting toggle switch, taking the cable from the wires with nylon screeds. Charging socket can be outlined to conveniently connect it to charge.

How to make a generator on 220 V

Also fix the fuel engine shutdown button

Stage Seventh: Trial Starting Aggregate

Checking all contact groups and fasteners of prefabricated elements, run the unit. Start and engine shutdown buttons must work flawlessly. It is worth noting that the starting battery is used for only a few seconds, and then turns off.

How to make a power station on firewood with your own hands

Power station on firewood - one of the alternative ways to maintain electricity consumers.

Such a device is capable of obtaining electricity at minimum energy costs, and even in those places where there is no power supply in general.

The power plant used by firewood can be an excellent option for owners of country sites and country houses.

Features

Firewall power plant - the invention is far from new, but modern technologies allowed to somewhat improved devices previously developed. Moreover, several different technologies are used to obtain electricity.

In addition, the concept of "on firewood" is not exactly accurate, since any solid fuel (firewood, chips, pallets, coal, coil) is suitable for the functioning of such a station, in general, everything that can burn.

Immediately note that firewood, and more precisely the process of their combustion, it only acts as a source of energy that ensures the operation of the device in which the generation of electricity occurs.

The main advantages of such power plants is:

  • The ability to use the most solid fuel and its availability;
  • Receiving electricity anywhere;
  • The use of different technologies allows you to receive electricity with the most different parameters (sufficient only for the usual recharging of the phone and before washing industrial equipment);
  • It can also act as an alternative if electricity supply interruptions are common, as well as the main source of electricity.

Classic option

As already noted, there are several technologies to produce electricity on firewood. The classic among them is the energity of the pair, or simply a steam engine.

Here everything is simple - firewood or any other fuel burning, heats the water, as a result of which it goes into a gaseous condition - steam.

The received steam is fed to the generator turbine, and due to the rotation, the generator generates electricity.

Since the steam engine and the generator unit are connected to a single closed circuit, then after passing the turbine, the pairs are cooled, it is fed to the boiler, and the whole process is repeated.

Such a power plant scheme is one of the easiest, but it has a number of significant drawbacks, one of which is explosive.

After the transition of water into the gaseous state, the pressure in the circuit is significantly increased, and if it is not adjusted, then the likelihood of the pipeline is given.

And even in modern systems, a whole set of valves regulating pressure, but still the operation of the steam engine requires constant monitoring.

In addition, the usual water used in this engine can cause the formation of scale on the walls of the pipes, which is why the efficiency of the station decreases (scale worsens heat exchange and reduces the bandwidth of the pipes).

But now this problem is solved by the use of distilled water, liquids, purified impurities falling into the sediment, or special gases.

But on the other hand, this power plant can perform another function - heating the room.

Here everything is simple - after performing your function (rotation of the turbine), steam must be cooled so that it moves to the liquid state again, for which the cooling system is needed or simply radiator.

And if you place this radiator indoors, then as a result, we will receive not only electricity from such a station, but also heat.

Other options

But the steam engine is only one of the technologies that is used in solid fuel power plants, and not the most suitable for use in living conditions.

Also for electricity are now used:

  • Thermoelectrogenerators (using the Peltier principle);
  • Gas generators.

Pros and cons of the power plant on firewood

Firewood power station is:

  • Availability of fuel;
  • The ability to get electricity anywhere;
  • The parameters of the electricity obtained are the most different;
  • You can make a device and yourself.
  • Among the shortcomings, it is noted:
  • Not always high efficiency;
  • The bulky structures;
  • In some cases, the production of electricity is only a side effect;
  • To obtain electricity for industrial use, you need to burn a large amount of fuel.

In general, the manufacture and use of solid fuel power plants is an option that deserves attention, and it can become not only an alternative to power grids, but also help in places remote from civilization.

Homemade Magnets

The magnetic generator is slightly different from the previous one. For example, he does not need to install compensatory batteries. The magnetic field that creates electricity in the stator winding is formed due to neodymium magnets.

How to create this type of generator:

  1. You need to unscrew the existing engine covers.
  2. Pull the rotor.
  3. The rotor needs to soak, while removing the top layer of the required thickness. It is difficult to make such a procedure without turning equipment.
  4. Make a template for round magnets on a sheet of paper. Select the required size is needed depending on the size of the rotor. Next, consolidate the created pattern on the rotor and install magnets with poles and at an angle of 20 degrees to the rotor axis.
  5. There should be four groups of bands with a distance of two diameters of the magnet, and between them in the group one diameter. Due to this location, the rotor will not stick to the Stator.
  6. After installing all magnets, it is necessary to pour the epoxy rotor. When it dries, you should cover the cylindrical part of fiberglass and again resin. Thanks to this mount, the magnets are firmly fixed.
  7. When drying the rotor, it can be placed in place and fasten two engine covers.

Magnets electric generator

Many specialists believe that there will be a pendulum with an axis of 6 m long to ensure electricity.

In this case, the electromagnets will push neodymium magnets with force more than 100 kg. The advantages of this device are that it does not depend on the Sun and the wind. In addition, the generator does not need expensive batteries as other energy generators.

But during its use, some problems are not excluded:

  • In the process of movement of the pendulum in the opposite direction, the polarity of magnets may be changed;
  • At the time of hanging the pendulum at the top point, the effect of ripples on the network may form.

Attention! With ferrite magnets, this project will not be implemented due to their technical characteristics.

General Tips for all types of homemade generator

Constructive execution

The autonomous power plant device must fully ensure the requirements of the safe operation of the working equipment and perform a single module that includes mounted electrical installations with devices:

  • measurements - voltmeter up to 500 volts and frequency meter;
  • load switching - three switches (one shared feeds the voltage from the generator on the consumer scheme, and the other remains are connected by condensers);
  • Protection - automatic switch that eliminates the effects of short circuits or overloads and Uzo (protective shutdown device), saving workers from breakdown of isolation and phase potential entering the body.

Reservation of the main power scheme

Creating a homemade generator, it is necessary to provide compatibility with the process of grounding the working equipment, and when autonomous work, it is securely connected to the contour of the Earth.

If the power station is created for the backup nutrition of instruments running from the state network, it should be used when the voltage is disconnected from the line, and during recovery - stop. To this end, it is enough to install a switch that controls all phases at the same time or connect the complex system for the automatic power on the backup power.

Voltage selection

The 380 volt scheme has an increased danger of human damage. It is used in extreme cases when there is no possibility of phase magnitude for 220.

Overload generator

Such modes create an excessive heating of the windings with the subsequent destruction of isolation. They occur when the currents passing through the windings due to:

  1. improper selection of capacitors;
  2. Connecting consumers of high power.

In the first case, it is necessary to carefully monitor the thermal regime during idling. During the excess heating, the capacitors capacitance are required.

Features of consumer connection

The total power of the three-phase generator consists of three parts produced in each phase, which is 1/3 of the total. The current passing on one winding should not exceed the nominal value. This should be considered when connecting consumers, distribute them evenly by phases.

When the homemade generator is designed to work from two phases, it cannot safely develop electricity more than 2/3 of the total value, and if only one phase is involved, then only 1/3.

Frequency control

Follow this indicator allows frequency meter. When it was not installed in the design of the self-made generator, you can use the indirect method: at idle the output voltage exceeds the nominal 380/220 per 4 ÷ 6% at a frequency of 50 Hz.

One of the options for the manufacture of a self-made generator from an asynchronous engine and its capabilities are shown in his video owners of Maria Channel with Alexander Kostenko.

If you have any questions about the topic outlined, you can ask them in the comments. Now convenient time to share this material with friends in social networks.

Operating tips

Asynchronous generator does not require special care. Its service is to control the status of bearings. At nominal modes, the device can work for years without operator intervention.

Weak link - capacitors. They may fail, especially when their rates are incorrectly chosen.

When working, the generator is heated. If you often connect Hypersed loads - follow the device temperature or take care of additional cooling.

Advantages and disadvantages of their own assembly

To positive sides The self-made manufacturer of the electric generator can be attributed:

  1. Increased self-esteem, which is extremely important for men. A well-assembled unit can be the subject of not only an alternative power source, but also pride.
  2. Significant financial savings.
  3. The ability to create such a device that would have answered all the claims.

Besides, The process may become more complicated and have a lot of negative consequences:

  1. Perhaps the unit will often break down, due to the impossibility of hermetic connection of all separations of the generator.
  2. Incorrect connection or power calculation will cause a malfunction of the generator, and will also reduce its productivity.
  3. A certain skill is required, as well as caution, since all work is carried out with electricity, with which, as you know, jokes are bad.

Output

Collect an autonomous source of energy is possible. And with a certain effort - almost free.

There are several reasons in order to have a miniature power plant. These are frequent interruptions in the supply of electrical energy in rural areas, and new construction, when electricity is not yet connected to the construction site. The best option is the purchase of a finished design. The market has a large selection of gasoline and diesel power plants of all sorts of ranges of output power. The problem becomes their high cost.

In the presence of the necessary parts and materials, as well as experience and desires, it is quite possible to collect a homemade benzogenerator.

How to make a generator with your own hands?

Electricity from the nearest LEP is not always configured uninterrupted. In summer cottages, where the light shutdown to one or a few hours is a frequent phenomenon, exclude generators with power supply. If there are some skills, they can be made with their own hands.

Features of homemade generators

The main feature, due to which many users of all sorts of gadgets are solved on a similar "homemade" - The ability to bring the generator to the power, which is enough not only to recharge the mobile phone, but also on the supply of laptop, television, and even homemade minorosis, not to mention the dozen LED lamps. As a rule, a variant of the device with the highest return at the output and the smallest accomplined efforts is selected.

The basis in any case is a reversible engine that works not only on the transformation of electricity into kinetic (mechanical) energy, but the opposite.

To make such a device, the user must have the following knowledge.

  • Wake up in electric hammers, be able to read them . According to one of them, a similar device is collected.
  • Have an idea of ​​how the electric generator works. The basis of its work is the law of Faraday: the number of magnetic lines of a permanent magnet, permeating the contour, should change, otherwise electricity will not be produced.
  • Have the skills of electrical and fitter work, be able to handle power tools. Previously, in Soviet times, a mandatory part of the educational program was not only physics, but also the conjunction (section of science on the resistance of materials). The fact is that the incorrectly selected elements of the supporting structures were connected in each other as required, with active loads quickly deform.

If you have all the above knowledge and desire, the user will easily collect the device, saving (compared to industrial) not one tet of thousand rubles.

Manufacture

Make your own hands the electric generator at home is easy. A simple magnetic generator is assembled on the basis of any of the finished engines: collector, step by step, etc. To assemble from zero such "homemade" can also be fixed by the magnets on the rotating axis and placing them in a rectangular coil that produces an electrostatic field during their rotation.

The electric generator on firewood is, in fact, the furnace (including hiking), on the walls of which peltier elements are fixed, closed with radiators. The essence of the Peltier effect lies in the fact that the plates from different conductors on the one hand are heated, and on the other, they are cooled. This leads to the appearance of electric current on the poles of such a plate. Best of all, a similar furnace-generator runs in the cold: the greatest difference in temperatures with each side of the plate leads to the development of maximum power.

Steam generator is a classic TPP in mini-execution . The stove with water circuit produces steam, served on the turbine blades. The heat energy of the pair causes the turbine to twist the motor generator, whose shaft is toughly connected to the turbine shaft. Such a system is closed: it requires periodic control from the side, as well as the presence of a cooling circuit in which steam will pass into the water.

This installation is very massive, you will not take it with you with you.

The generator on the basis of an asynchronous engine operating from 220 volts - This is a device with three stator spaced windings (motionless part of the motor). Since the motor itself is operating from 220 or 380 (in a three-phase network) Volt, then it will produce the same tension, it is only worth unwinding his shaft at least up to 50 revolutions per second. It is not needed to collect it: to use the finished unit, to the windings, only you will need to connect additional condensers.

Tools and materials

A suitable engine is taken as the operating module of an electromagnetic (mechanical) generator. Multi-type engines are used: collector (brush), uncoolette, stepper (brushes and rings are not used), synchronous and asynchronous. Depending on which current is generated, the following parts and nodes apply.

  • Rectaging diodes. Convert alternating current to permanent. There are high-power diode bridges, designed for current in dozens of amps and voltage up to 50 V.
  • Polar capacitors . Designed for permanent current. Play the role of smoothing filter, leveling constant voltage ripples.
  • Extra charge with USB port - converts a voltage of 1.5-20 volts to the necessary smartphones, tablets and most laptops 5. Books on Aliexpress.com and in other online stores.

All these radio components are needed when the motor generator gives no more than a pair of dozens volts.

Using, for example, an asynchronous engine will require the connection of your gadgets and other devices in normal mode - both from the household outlet.

Auxiliary materials can be anyhow, as they play the role of the supporting structure:

  • wooden bars;
  • Metal fittings;
  • profiles;
  • Fastening compounds (bolts with nuts and washers, clamps, brackets, clamps, brackets, screws);
  • pipes of any diameter, etc.

The following products apply as power tools.

  • Bulgarian With a set of cutting discs (for metal and wood) and grinding (comes in the form of an eattered circle or a universal solid disk).
  • Electric drill With a set, rolled metal. If it is installed, for example, a wind generator with a support on the wall of the house, it may be necessary to take a standard perforator with a set of drum drums and / or concrete crowns. The perforator can also be equipped with an adapter for simple or tapered rods and crowns on wood.
  • Sculpture. It will be necessary when the design is massive, and screw the screws in an amount from several tens. It can be completed with the heads under the adapter-wrench or universal head under the nut, resembling an adjustable key.

Prepare the desired inventory, proceed to the process of manufacturing the generator set.

Assembly scheme

The asynchronous generator has the property of self-synchronization: the inclusion of a rotor winding in operation without meals, in which a constant magnetic field is excited. Self-excitation of the winding of a short-circuited rotor is made due to the phenomenon of residual magnetization. To assemble an asynchronous generator, follow the instructions below.

  1. Place the engine and transmitter on one carrier design.
  2. Connect to windings Variables (non-polar) capacitors . The windings themselves are included according to the "Star" scheme: some ends are converged in the center (on the body), the others are derived separately.
  3. Capacitors are connected according to the "Triangle" scheme: free ends of the windings are connected to its vertices. . Engine power - 2-5 kilowatt, capacitance capacitors - 28-138 microfrades. Pick up such a container so that the voltage generated does not decrease - depending on the load, which is planned to be used.

Before starting the generator, make it testing. The test can be performed using a conventional incandescent bulb for several dozen watts. The task is to ensure the uninterrupted issuance of the produced voltage. This will require an installation capable of issuing 3000 revolutions per minute. For example, a powerful windmill with a gearbox (or chain drive), a fuel engine from any unit, hydroturbine on the river, etc.

The fact is that a person alone will not be able to unwind any motor generator into power over 150 W, whatever efforts fit. Here it is limited.

The manufacture of an asynchronous generator is the simplest alteration of the scheme of the finished engine. The rotor flows for neodymium magnets are not required, which you can not say about the car generator, in which the power of the rotor winding is made from the battery. By the way, most modern automotive generators are based on a synchronous motor in which the speed of revolutions is rigidly connected with the frequency of the current produced. To get rid of the need to feed the rotor winding, you can redo the engine, removing this winding and overshable the axis of the rotor under flat magnets.

To assemble the generator on firewood, do the following.

  1. On the wall of the bourgeitry or pyrolysis furnace Place the "spikes" radiator inside.
  2. Mount On it one or more elements of Peltier, focusing on the radiator area.
  3. Attach to the element Peltier is another radiator.
  4. Position the installation on the shadow side of the house in a specially reserved place. The wall should not have insulation, as well as be too thick at this point, as you need access to street cold. The ideal option is the technical room compartment for such a stove, in which there is a retrach vents for burning firewood. The radiator is located next to it from the cold side.

The launch of such a generator is carried out during the ignition of firewood. When the firewood spars, the Peltier element will give maximum power. It will be cooled with cold air setting from the street. The process of heating will provide the wall of the stove.

To build a collector generator, it is recommended to use the following instruction.

  1. Place the collector motor on the carrier frame or another design.
  2. Configure the DC smoothing capacitor and the converter board (DC inverter) to its outputs.
  3. Connect the USB port to the DC-card output (if it is not equipped with it).
  4. Position the generator on the bike frame either make a "windmill" for it (for example, from the parts from the fan with the failed engine). In the latter case, for the convenience of the "windmill" there is a vane-shank, turning the design to the other side where the wind blows.

Connect your smartphone, tablet, mobile phone, smart clock or other device. The motor from the printer, for example, produces up to several watts of power: so, at 12 volts, which it is designed, the current can reach 600 milliam. Disadvantages of collector engines: Low efficiency and frequent replacement of brushes.

Working every day for several hours, the brushes will serve as a maximum of 2-3 months.

Instead of the collector electric motor, use stepper: its efficiency is significantly higher, it is able to serve not one ten years. In online stores, full models giving voltage at 12 volts and a current of 1.8-4.2 amps. The windings at the stepper motor can be 2, 3 or 4. When turning them in consistently, you will receive 24, 36 or 48 V. Parallel inclusion. Dast is proportionally more amperezh. "To dispersed" the generator to the desired voltage rating will be more difficult.

Operating recommendations

The generator used in the street conditions (wind power station for a private house, cyclenener) is recommended to be protected from rain, road dirt and other extraneous particles by placing it in a separate case.

A device that works in street conditions in the multi-hour daily load mode needs regular (at least half a year) lubrication of bearings. They, in turn, are in each motor generator.

Shooting of the engine and auxiliary electronics is not allowed. The closed engine is promoted several times more difficult at the expense of the rotation of the power rotor, proportional load. Winding, closed in short with a spinning shaft, can burn. Semiconductor electronics (solar panels, Peltier elements) also fails, being closed.

About how to make a generator with your own hands, look next.

For most people, the homemade generator is associated with the converted electric motor. In fact, it can be done differently, literally from scratch. And this is absolutely not difficult, quickly and inexpensive.

Electricity is not always fed uninterrupted, for example, due to the remote location of the power transmission from residential buildings. And when will the light turn off the light, you probably wondered about the purchase of the generator? Of course, the purchased device is the cheapest solution, and the costs are not always justified. A more affordable option is to make a generator with your own hands. Such a solution does not require large investments on the assembly, it can transform energy not only due to expensive gasoline, diesel engine, but also more affordable - gas, steam, etc.

Therefore, he solves the problem with the interruptions of electricity and saves an enon sum in the budget. But how to make a really high-quality generator, what else do the homemade benefits before purchased devices? We will help you to figure out all the nuances - in this article we present the circuit of the assembly of the electric generator, the principle of its work, the advantages of using self-made. We will also consider step-by-step instructions for the manufacture of the generator at home.

Advantages of self-made generator

The homemade generator wins the purchased more affordable cost. Of course, the financial side is important, but the device made by its own hands is the device only with the necessary and declared requirements.

It is worth considering that the selected design directly affects the efficiency. So in asynchronous generators, the efficiency of the efficiency does not exceed 5%. The laconicity of the design of its housing with the protection of the engine from moisture, the dirt reduces the need for a frequent maintenance. The asynchronous generator is more resistant to voltage jumps due to the rectifier at the output, which prevents the connected equipment breakdown.

The operation of the electric generator

The homemade generator works regardless of the transfer of power transmission, providing electricity in any conditions. It converts energy using the available type of fuel.

Such a device effectively feeds welding machines, incandescent lamps, computer and mobile equipment with sensitivity to voltage drops. It has good performance and motor life.

The device is a good alternative to conventional power sources, cuts off with an emergency disconnection of electricity, saves funds. Mobile, small-sided, with a simple design, it is easy to repair - you can replace the details, knots on its own forces.

Among other things, homemade has small size, so it is easily installed even in small rooms.

Placing a homemade generator

Place the homemade generator can be in a small room, due to the compact design, the device does not require a lot of space for its installation

Depending on the type of fuel used, the generator requires only compliance with precautions during use.

Safety using the generator

During the operation of the homemade generator, it is necessary to comply with the safety technique: monitor electrical cables, not allow them to twist, do not touch the bare wires by hand, etc.

Varieties of electricity generators

Usually, the homemade generator at home is made on the basis of an asynchronous engine, magnetic, steam, on firewood.

Option # 1 - Asynchronous generator

The device will be able to produce a voltage of 220-380 V, based on the indicators of the selected motor.

To build such a generator, you will only need to run an asynchronous engine, connecting the condensers to the windings.

An asynchronous engine based generator is synchronized independently, starts rotary windings with a constant magnetic field.

Engine for an asynchronous generator

The engine is equipped with a rotor with a three-phase or single-phase winding, an input of a cable, a short-circuit device, brushes adjusting the sensor

If a short-circuited type rotor, then the windings are excited using the residual power of the magnetization.

Option # 2 - Device on magnets

For a magnetic generator, a collector is suitable, stepper (synchronous brushless) engine and others.

48-pole magnetic generator

The winding with a large number of poles increases the efficiency of the efficiency. In comparison with the classic scheme (where the efficiency of 0.86) 48-pole winding allows you to make the generator power more

In the process of assembly, the magnets are attached to the rotating axis and are installed in a rectangular coil. The latter when rotating magnets produces an electrostatic field.

Option # 3 - steam generator

For a generator, a pair use a stove with water contour. The device operates due to the thermal energy of steam and turbine blades.

Homemade generator for a couple

To independently make the generator for a couple, you will need a stove with water (cooling) circuit

This is a closed system with a massive non-clean installation, requiring control and cooling circuit to convert steam into water.

Option # 4 - device on firewood

For the generator on firewood use furnaces, including hiking. Peltier elements are fixed to the walls of the furnaces and the design is placed in the radiator body.

The principle of operation of the generator is as follows: When the surface of the conductor plates is heated, on one side, the other is cooled.

Homemade generator on firewood

To independently make the generator on firewood, you can use any ovens. The generator works at the expense of Peltier elements, heating and cooling conduction plates

Electric current appears on the poles of the plates. The greatest difference between the temperatures of the plates provides the maximum power generator.

The unit is more efficient for minus temperature modes.

The principle of operation of the electric generator

The operation of the generators is implemented according to the principle of electromagnetic induction, when a current tank occurs in the closed frame due to the intersection of it with a rotating magnetic field. The magnetic field creates windings or permanent magnets.

When the electromotive force from the collector reaches a closed loop and brush nodes, the rotor begins to rotate together with the magnetic flux. This is how the tension in spring-loaded brushes pressed to the collectors of a plate view.

Next, the electrotok is transmitted to the output terminals, passes to the network, spreads through the generator.

AC and DC generators use. An alternating current electric generator is small, does not form vortex currents, while it is possible to function in extreme temperatures. A constant current does not require careful control, has a significant number of resources.

Generator design

Constructive generator includes: brushes with brush holders, manifold, anchor winding, anchor, starter, contact rings, starter winding, rotor, body, fan, drive and bed

AC generator can be both synchronous and asynchronous. The first - with a constant electric magnet and the number of rotational of the stator equal to the rotary, forming a magnetic field. The advantages of such a generator are a consistently high voltage, the disadvantages include overcurrent on currents due to the overestimated load on the regulator, which increases the rotor winding current.

Asynchronous generator design: short-circuit rotor, stator. When the rotor rotates the generator induces the current, and the magnetic field gives the sinusoidal voltage.

Step-by-step assembly instructions

Collect the generator at home is necessary after a kit is prepared from the necessary radio components, power tools and materials.

Stage 1 - Preparation of Radio Components

To build a module of a mechanical generator with electromagnets, an engine will be required. For the manufacture of a low-power generator, an electric motor can be used from the "Oka", Volga type, the pump "Agidel" and others.

The current generated by the engine determines the choice of parts and nodes. To convert current from the variable to constant, rectaging diodes are needed, for example, a high-power diode bridge in dozens of amps with a voltage of no more than 50 V. For polar constant current capacitors, smoothing filters are important with the ability to align constant voltage pulsation.

Homemade wind generator device with propeller turntable

In order to make a self-made wind generator, it will not be required to make a great accuracy of execution and highly specialized materials. The constructed sample works at wind speed from 9 to 10 m / s, provides a capacity of 800 W.

As an additional fee with a USB port for connecting gadgets, a device for converting voltage in 1.5-20 V. This list of radio components is sufficient for a low-power generator with a voltage to two dozen volts. In the case of an asynchronous engine, connect mobile devices directly.

Stage 2 - Preparation of Tools and Materials

From the power tools you will need Bulgarian, in the set of which there are cutting discs for metal, wood and grinding disk (solid or circle sandpaper).

We recommend to familiarize yourself with.

An electric drill is also needed with metal drills. You may need a perforator with shock drills, crowns on concrete. Sometimes the perforator is equipped with an adapter with simple, conical drills, crowns on wood. A screwdriver with heads under the adapter-wrench, head under the nut.

For the assembly of the generator framework, materials will be required. They are chosen at their discretion. It can be a tubular rolling of different diameter, metal fittings, profile, etc.

Toolkit for assembly

During the assembly of the generator design, the master should be screwdered a screwdriver of different diameters, planks, a hammer, wrench and so on

For the connection, they are equipped with fasteners - nuts, washers, screws, bolts. This is a universal set of inventory, assembling which, you can proceed to the manufacture of the generator installation with your own hands.

Stage 3 - Preparatory Work

After the preparation of tools and materials proceed to preparatory work. They are necessary before assembling the generator because they include the initial calculation of the power of the device.

Calculate power by connecting the engine to the network. The number of rotations issued will determine the power of the motor. Sometimes a tachometer is used for measurements, and 10% is added to the data obtained to compensate for the load (preventing the motor overheating when used).

After the power is accurately calculated, the capacitor is selected according to the previously obtained data of the engine power.

Engine condensers

After counting the power, you must select a capacitor. The device prevents motor overheating during generator operation

At the end of the preparatory work, it is thought of grounding of the future generator. This process helps to avoid traumatic situations, extend the operating time of the generator.

Stage 4 - Study of the Star and Triangle Scheme

To assemble the generator in 220, a schema-analogues of the production model - a star or a triangle are required.

Star and Triangle Assembly Schemes

In complex devices, sometimes use a combined triangle star scheme. In the connection of the style of the star, the ends are attached at a single point. The graphic view is the discrepancy of the phases from the center in different directions, as if the rays form a star. According to the type of triangle, the ends of one winding are attached with the beginning of the subsequent

According to the star scheme, the electrical connection is performed for each of the ends of the windings of one point, for a triangle - a consequence of a sequential type.

Stage 5 - directly assembly

Consider several options for assembling the electric generator.

Asynchronous generator assembly

The manufacture of an asynchronous generator does not require a rotor interference to neodymium magnets, so the device circuit is called the alteration of the finished asynchronous motor. In this option, there is no need for the power of the rotor winding, it is removed from the engine, and the rotor axis is pulled out for flat magnets.

According to the assembly scheme of an asynchronous generator, the power of the device reaches from 2 to 5 kilowatt with capacitance of capacitors from 28 to 138 microfrades. In order for the voltage to be static, the container is necessary, depending on the planned load on the generator.

The assembly of the unit occurs in three stages. The first suggests collecting one carrier design by setting a gear-type drive in it.

Connecting windings according to the triangle scheme

The connection is performed as follows: The end of the 1st winding is connected to the seams of the beginning of the 2nd winding. Next, the end of the 2nd winding is fixed to the beginning of the 3rd winding. The end of the 3rd winding is connected to the beginning of the 1st winding.

In the second stage, variables and non-polar capacitors are connected to the windings. The latter are included according to the star scheme when the part of the ends are connected to the center of the housing, and the rest are displayed separately.

In conclusion, there are free winding ends according to the condenser's vertices according to the triangle scheme.

Connecting variables and non-polar capacitors

We connect variables and non-polar capacitors to the windings, part of the ends that connect to the center of the housing, others output separately

Before the first launch, the new device is tested, for example, a conventional incandescent bulb in two or three dozen watts. This is necessary to verify the generator on the ability to ensure uninterrupted voltage issuing, 3000 revolutions in one minute.

Collect the generator on firewood

Assembling wood generator Consider on the example of the bourgear. The order of assembly is: at the beginning, the radiator is placed on the walls of the bourgear so that the spikes look inside. Further, depending on the size of the radiator, the elements of Peltier are installed, one of which is subsequently fixed by another radiator.

Such an installation is better located in the shade, near the lavety wall of a small thickness, which will ensure maximum cooling.

To start the generator on firewood ignites landslies. Finding, they heat the stove walls that force the Peltier element to produce maximum power. Cooled by a cold outdoor generator.

Our site has a detailed instruction on your own hands.

Collector generator assembly nuances

The collector generator is collected according to the following scheme: first place the collector-type motor on the carrier frame, another design.

Then attach a smoothing capacitor, a DC inverter board to the outputs of the motor. The capacitor must be direct current.

Assembling collector generator

It is necessary to fasten the cartridge to the axis of the engine, while the motor is consolidated so that the cartridge is tightly pressed to the device. Next, the minor wire of the motor is joined to minus from the battery, and the plus to the attachments of the diodes, the cathodes of diodes to the pluses of batteries

The next step, if there is no USB port, will connect it to the output from the DC fee. Mobile devices can be connected to such a generator.

The design of the generator on the bicycle frame or windmill is located.

Installing the generator by bike

We establish a generator on a bike or windmill from fan spare parts. For ease of use, you can attach a fluger-shank

Instead of the collector, you can put a stepping motor with a higher efficiency and service life of 10 years. It is preferable to select models with a voltage of 12 V and a current from 1.8 to 4.2 amps. In such motors of windings from 2 to 4, they are connected in series for voltage in 24, 36, 48 V. If the motor is connected parallel, then an amperezh is obtained in a large value at the output. In this regard, to the desired voltage, the generator will accelerate more difficult.

In addition to these options, we have detailed instructions for assembling and generator.

Recommendations for safe operation

For generators who will be used in a street environment, such as a wind power station, a cyclenener, it is necessary to create protection against precipitation, dust, dirt. The device is placed in a special separate case.

If the generator works on the street in a multi-hour mode, testing everyday loads, it needs regular lubricants of bearings. Manipulations spend one or twice in half a year.

Not allowed short circuit: engine wires, auxiliary radio electronics, semiconductors. This can lead to the fact that closed windings will be burned.

Engine repair

If a short circuit happened, the engine repair can be complicated by the complexity of access to the internal parts of the generator

The engine repair can be complicated by the difficulty of accessing the internal nodes due to the power of the rotor, which slows down rotation is proportional to the load. To prevent such situations, the engine temperature should be constantly monitored, without letting it overheat.

You should also try not to use the device for a long time: the longer the generator in operation, the more power is less. The value of the optimal engine temperature is from 40 to 45 degrees.

For a homemade generator without automatic control devices, constant user control is required, including to remove the data.

If the assembly and use of the self-made electric generator seems difficult to you, we recommend to look at purchased analogues - the next article provides gas generators of electricity.

The generator is a device that produces products producing electrical energy or converting it to another. What is the device, how to make a generator, what is the principle of its work, what is the difference from the synchronous generator? Tell me further.

Device and principle of operation

The generator is called an electric machine, which is engaged in the transformation of mechanical energy into current electricity. In most cases, the rotational type of magnetic field is used for this. The device is made of a relay rotating inductor, contact rings, a terminal, a sliding brush, a diode bridge, diodes, a toxal ring, stator, rotor, bearings, a rotary shaft, pulley, impeller and anterior cover. Often, the design includes a turn with an electromagnet that produces energy production.

Generator do it yourself

It is important to note that the generator is AC and DC. In the first case, vortex currents are not formed, the apparatus can work under extreme conditions and has a reduced weight. In the second case, the generator does not need elevated attention and has a greater number of resources.

The alternator is synchronous and asynchronous. The first is an aggregate that works as a generator, where the number of rotational rotations of the stator is equal to the Rotor. The rotor forms a magnetic field and creates in the EMF stator.

Note! As a result, a constant electric magnet is created. Of the advantages, the high stability of the created voltage is noted, from the disadvantages - current overload, since with an overestimated load, the regulator increases the current in the rotor winding.

Synchronous device

The asynchronous apparatus consists of a short-circuited rotor and exactly the same stator as the previous model. At the time of rotation of the rotor, an asynchronous generator induces electrical strokes and a magnetic field creates a sinusoidal voltage. Since it does not have connection to the rotor, then the possibility is to artificially adjust the voltage and current, no. These parameters vary under the electrical load on the starting winding.

Device asynchronous machine

Operating principle

Any generator acts according to the electromagnetic inductive law, due to the tip of the electric flow in the closed frame with the intersection of the rotating magnetic field created by the help of permanent magnets or windings. The electromotive force enters the closed circuit from the collector and the brush node along with the magnetic flux, the rotor rotates and produces voltage. Due to spring-loaded brushes, which are pressed against the plate collectors, transmitted electricals to the output terminals. Further, it goes to the user's network and applies to electrical equipment.

Principle of operation

Difference from a synchronous generator

The synchronous gasoline generator is not overloaded due to transient modes that are associated with a start-up load from the consumers of this power. It is a source of reactive power, while asynchronous consumes it. The first is not afraid of overloads when the mode is set thanks to the control system through the connection, which is inverse the voltage current in the wire. The second has an unregulated artificial force of the clutch of an electromagnetic rotary field.

Note! It is important to understand that asynchronous variety is more popular thanks to a simple design, unpretentiousness, lack of need in technical qualified maintenance and comparative cheapness. It is raised when: there are no high requirements for frequency with voltage; It is planned to work as an aggregate in abed place; There is no possibility to overpay for another variety.

Synchronous variety

Application area

AC generator is a multifunctional device, due to which energy can be transmitted over long distances and at the same time it is quickly redistributed. In addition, it turns into light, thermal, mechanical and other energy according to the instructions. Easy to manufacture. Therefore, the scope of their use is extensive. Today, such devices are used everywhere: both in industry and in terms of life. They equip the powerful motor.

For example, the electro and the wind generator will be useful at the time when the volt network is turned off, an accident will occur at the power plant, there will be an additional energy in the engine.

The gasoline and magnetic generator, due to low weight and compactness, can be transported and used in agriculture, in the country, in the forest. It will serve as a quick response and will help create emergency lighting.

Application area

Classification of the device

The classification of the device is extensive. Today it is asynchronous and synchronous, with a fixed rotor or a stator, single-phase, two-phase and three-phase, with independent or independent excitation, with excitation windings or excitation from a permanent magnet.

Note! It is worth noting that at the moment three-phase models are more popular with a rotating circular magnetic field, system equilibrium, work in several modes and high efficiency coefficients.

Classification of equipment

Device assembly scheme

Collect electric generators on 220 with their own hands by analogy with the production model. For this, you may need video tutorials or textbooks. Then you need to properly connect all the instruments of one system. You can do this by a star or triangle scheme.

In the first case, the electrical connection occurs for all ends of the windings of one point, and in the second case, a sequential type of winding generator connections is provided. It is important to note that these schemes can be used only if the phase load is uniform. Then the topic, how to make a generator at home will be relevant.

Star Connection Scheme

In general, the generator is called a device that converts mechanical energy into electrical with a wire variety of a magnetic field coil. By the number of phases, aggregates are with one, two and three phases.
