It is not easy to get such a generator, as the work requires patience and some turning work. For it, a conventional asynchronous electric motor is used, which is available in automatic washing machines. It has a power of 170 ... 180 W; a generator based on such an electric motor will have 1.5 kW of power.

In addition to the engine itself, you should stock up on: cold welding; 32 neodymium magnets of different (5, 10, 20 mm) diameters; glue; rectifier; sandpaper. You will need a lathe; scissors; different screwdrivers; pliers.

First, the rotor of the engine is reworked in order to install magnets on it in the future. The cores are removed and placed in a lathe, they are cut to a 2 mm depth. 5 mm deep grooves are also arranged.

To plant the magnets, a coating is made, which is then wrapped around the core. Tinplate is used. The diameter of the resulting template, the holes in it must correspond to the core, which is necessary for its tight abutment to the surface of the latter.

The magnets are placed with equal gaps between each pair of magnets. If this is not done, then in the future they will stick together and loss of power of the electric generator. Placement of magnets is carried out on a strip of tin, which is first glued to the core with superglue. They do this exactly, excluding any inclination of the elements.

After the template with the glued magnets is placed on the rotor, fill with epoxy resin, cold welding all the gaps that are between the parts. Then the rotary surfaces are cleaned with sandpaper until smooth.

At the stator, wires are found that lead to the working winding. They are looked for with a multimeter. They differ in the same resistance. The rest of the wires are unnecessary and can be cut.

To check the generator, the working winding is connected to a rectifier, which must be connected to the battery through the controller. The clamps of the multimeter are connected to the latter in the voltmeter mode.

Then, using a drill, a screwdriver, the rotor of the generator is spun up to 800 ... 1000 rpm. The multimeter should show an output voltage of 200 ... 300 V. If it is small, then most of all, an inaccuracy was made when placing the magnets - they are laid out on a template with different gaps between pairs.

Having made a generator and installed it on a chainsaw, we got a small power station. The electricity it gives out is enough to light up two small rooms, to give work to a TV set, a computer. Instead of a chainsaw, you can arrange a wind turbine to rotate the rotor.

The electric motor from a washing machine is very easy to find in view of the fact that it rarely fails in comparison with other units, and the machines themselves are thrown into a landfill all the time. The thing for homemade people is very valuable, I take into account how many simple machines can be built on its basis.
This motor may well work as a generator. But unfortunately, just like that, he will not generate energy, since there are no permanent magnets in it that can create an EMF in its windings.

How to start the engine from a washing machine as a 220 V generator

The motor from the washing machine has a classic structure of a collector electric motor. And it can work from both direct and alternating current. It's all about managing it.
Typically, the motor from the washer has 6 terminals on the connection block: the first pair from above are the outputs of the tachometer sensor, we do not need them to control the speed. The second two in the middle are the output of the stator winding. The third lowest pair is the rotor leads.

To get the motor to generate current, you need to apply some voltage to the rotor. This will create a magnetic field on it, which in turn, as it rotates, will create an EMF on the stator winding.
We connect the wires to the rotor, to which the power supply will be connected in the future.

We connect the wires to the stator. To the ends of the wires - a multimeter for measuring the output voltage.

For demonstration, we turn the motor shaft without a source connected to the rotor.

As a result, the multimeter showed zero volts and this is understandable.
We connect the power supply. It will be played by a 3.7V lithium-ion battery. Again, turn the shaft by hand.

The multimeter gave a certain value, which means that energy is being generated.
Change the 3.7 V battery to a 12 V battery. Rotate by hand.

Result: the tension rises.
To create a greater torque corresponding to the operating speed of the engine, we wind a winch on the pulley.

Let's tug, creating a rotation.

Although the multimeter shows 75 V, in real life the voltage is higher, since the electronic device has a delay and is not able to count instant surges of electricity.
For clarity, we will connect a 220 V incandescent lamp. We will also wind the winch and pull it.

The light will flash for a short time.

Conclusion

The motor from the washing machine is quite suitable as a voltage generator, but it is difficult to "attach" it somewhere, since it: produces a constant current, requires high speed, requires additional power for operation, and if it stops, this power must be somehow turned off.
But there are pluses: the output current can be easily controlled by adjusting the current of the rotor circuit, there is no magnetic sticking, small size compared to permanent magnet generators.

A wind generator is a great alternative to electric power sources. It is used for private houses, remote from power lines and as an additional power source. In this article, we will tell you how to make a mini-windmill from available tools (washing machine, scrap metal, broken household appliances) with your own hands.

A wind generator is a set of mechanical devices related to an alternative source of electricity, which convert the kinetic energy of the wind into mechanical energy using blades, and then into electrical energy.

Wind turbine - an alternative source of energy for a private house

Modern models have three blades, which provides a higher efficiency of the installation. The minimum wind speed at which the wind turbine is started is 2-3 m / s. Also, the technical characteristics always indicate the nominal speed - the wind indicator at which the installation gives the maximum efficiency, usually 9-10 m / s. When the wind speed is closer to 25 m / s, the blades become perpendicular to the wind, due to which the power generation drops significantly.

In order to provide a private house with electricity, at a wind speed of 4 m / s, it is enough:

• 0.15-0.2 kW for basic needs: room lighting, TV;
• 1-5 kW to ensure the operation of the main electrical appliances (refrigerator, washing machine, computer, iron, etc.) and lighting;
• 20 kW will provide energy to the whole house, including heating.

Because the wind can stop at any time, the wind turbine is not connected directly to electrical appliances, but to batteries with a charge controller. Because rechargeable batteries produce alternating current, and household appliances need a direct current of 220V, install an inverter, to which all electrical appliances are connected. The disadvantages of wind generators include noise and vibration generated from them, especially for powerful installations, more than 100 kW.

Types of wind turbine blades

The main parts of the wind turbine

To make a homemade windmill, you need to know what main parts it consists of and what they can be replaced with:

• The rotor is a rotating part of the installation, powered by wind power. It can be bought at a store or removed from a non-working unit (engine or from a drill generator).
• Blades. They are usually made from wood, light metal (aluminum) or plastic. They can be of the sail type (like a windmill) and vane.

Advice! The vane profile blades are more efficient.

• A generator is a device that converts wind force into electrical energy. You can make it yourself from magnetic coils or remake a ready-made washing machine or car generator.
• The tail is an element that helps orient the windmill in relation to the wind. It is made of wood, light metal, plexiglass or plastic.

Schematic: wind generator device

• Horizontal yard to support generator, wind turbine and tail.
• A mast, on which a yard with a generator is movably attached. It reaches lengths from 5 m to 20 m and is made of durable wood or plastic / iron pipe with a hollow interior with a conduit for the outlet of the electrical wire. It is secured with steel cables for added security.

Advice! The higher the wind turbine match, the more energy it will generate.

• The wire connecting the generator and the shield. And the switchboard itself consists of:

1. battery. It is best to use special devices for alternative energy systems;
2. battery charge controller;
3. inverter.

How to make a generator for a wind turbine from a washing machine

As a generator for a wind turbine, it is best to use an asynchronous motor, which is used in old-style washing machines.

Attention! The main problem with homemade generators is sticking magnets. To avoid this, they are installed at a slight incline.

We make the holder, axle and blades

How to install a wind generator

• We install the generator, blades, rotor and tail on the carrier rail. In this case, it is necessary
  close the generator and the wind turbine rotor with a special cover to protect it from atmospheric influences.

Advice! For protection against cold, the unit can be coated with a silicone based grease.

• The power plant is mounted on the rail with a movable hinge mechanism.
• The mast is fixed to a concrete base with 4 bolts.
• A wire is drawn along the mast from the generator to the switchboard.

The wind generator is installed in calm weather.

• After that, the voltage controller, battery and inverter are connected.
• The installation is connected to test devices, during normal operation it is reconnected to the network.

Attention! Before connecting complex household appliances to the network, check the operation of elementary ones, for example, a charger for a phone.

A wind generator is an environmentally friendly option for generating electricity. Small wind turbines are perfect for summer cottages or as an additional power source in private houses in the absence of light. In order to do it yourself, you need to have basic knowledge of electrical and electronics. It is advisable to read the video instruction for more information.

Wind generator from a washing machine motor: video

This article will look at converting an engine from a washing machine to an electric generator. All the stages of rework will be step by step described and illustrated, so if you have a broken washing machine, do not rush to throw it away!

Clean energy derived from natural resources is one of the hottest topics today. Imagine that you have a generator in your country house or country house that supplies all the resources of your household with free electricity. It can be a wind turbine or a water turbine - it doesn't matter. Do you think these are all fairy tales? Not at all.

In fact, these are technical developments that are not so difficult and expensive to implement at home with your own hands.

Today we would like to present one of such options based on a brushless DC motor. The author proposes to remount such an engine from a washing machine into a generator by re-soldering the stator driving coils in a special way. After this conversion, the engine can be used for a wind turbine. And if it is equipped with a water intake device like a Pelton turbine, then a hydroelectric generator can be built.

Required materials and tools

As you probably already understood, today we only need the engine itself from the washing machine. The author used an inverter DC motor from the American Fisher & Paykel washing machine. Similar engines are used in its products by LG, which is present in our domestic market.

We also need:

• Soldering iron, flux and solder;
• Hot glue;
• Fine-grained sandpaper - zero.

Instruments:

• Nippers
• Pliers
• Painting knife

We start to remount the engine

For work, it will be necessary to dismantle the engine from the machine body. It has three main parts:

• The stator is a circular platform with leading winding coils located along the outer edge of the circle;
• The rotor is a plastic or metal cover with a plastic core. Perimeter magnets are placed along the perimeter of its inner wall;
• Shaft - the central part of the engine, equipped with bearings for transferring kinetic energy to the washing machine drum.
  We will work directly with the starter.

Stator preparation

We place the engine platform on the table and get to work. Our goal is to re-solder the phase connections according to a different scheme than the original (photo).

For convenience, you can mark groups of 3 coils with a marker. Cut each of the 6 coil outputs with pliers according to the diagram.

The cut edges must be turned off with a screwdriver or by hand, so that it is more convenient to work with them later.

We clean each contact with fine-grained emery paper to improve the adhesion.

When everything is ready and free of debris, we connect together every second group of three contacts. Strengthen the manual twist with pliers.

With a soldering iron, we tin the twist with the help of a flux, and we solder it with tin solder. We open the twist, and we solder it from the reverse side. We do the same with the rest of the contacts. As a result, we should have seven twists.

Loopback of phases

We clean the contact group used to supply power to the engine.

Now you need to loop the remaining 3 phases. We select the ring for the first phase. We make it from a piece of copper stranded cable. Mark and cut it to fit the inner circumference of the platform.

We strip the insulation at the junction with free contacts, and clean them with sandpaper. We begin to solder the ring from the contact group, going through each of the seven, we finish with the last contact. For the reliability of the connection, we tie the end of the contact on the ring.

We loop the second and third phases by analogy with the first. Care must be taken not to solder adjacent contacts together.

Insulation application

Our engine conversion for a generator is ready. It remains only to isolate the spikes on the ring and coils. An alternative method was used by the inventor, using hot glue as an insulator.

According to him, such isolation has never failed. However, for those who are not sure about this method, it is worth using electrical tape. At the end of the work, the engine is assembled and can be used in a prefabricated generator set.

Homemade products from the engine from the washing machine (video selection, photos, diagrams)

1. How to connect a motor from an old washing machine with or without a condenser

Not all "washing" motors will operate with a capacitor.

There are 2 main types of engines:
- with capacitor start (permanently switched on capacitor)
- with a starting relay.
As a rule, "capacitor" motors have three winding leads, power 100 -120 W and speed 2700 - 2850 (washing machine centrifuge motors).

And motors with a "start relay" have 4 outputs, power 180 W and revolutions 1370 - 1450 (washing machine activator drive)

Connecting a "capacitor" motor via the start button may result in a loss of power.
And the use of a permanently switched capacitor in a motor designed for a starting relay can lead to burnout of the windings!

2. Homemade emery from the washing machine engine

Today we will talk about converting an asynchronous electric motor from a washing machine to a generator. In general, I have been interested in this issue for a long time, but there was no particular desire for reworking the electric motor, since at that time I did not see the scope of the generator. Since the beginning of the year, work has been going on on a new model of the ski lift. It's a good thing to have your own lift, but it's much more fun to ride with music, so I quickly got the idea to make such a generator so that I could use it to charge the battery on the slope in winter.

I had three electric motors from the washing machine in store, and two of them are absolutely serviceable. I decided to convert one of these asynchronous electric motors into a generator.

Running a little ahead, I will say that the idea is not mine and not new. I will only describe the process of converting an induction motor into a generator.

It was based on the 180-watt electric motor of a washing machine made in China in the early 90s of the last century.

I ordered magnets from NPK Magnets and Systems LLC, before I had already bought magnets during the construction of a wind farm. Neodymium magnets, magnets size 20x10x5. The cost of 32 pieces of magnets with delivery is 1240 rubles.

Alteration of the rotor consisted in removing the core layer (deepening). In the resulting recess, neodymium magnets will be installed. At the beginning, a 2 mm core was removed on a lathe - a protrusion above the side cheeks. Then a 5 mm recess was made for the neodymium magnets. The result of the rotor rework can be seen in the photo.

Having measured the circumference of the resulting rotor, the necessary calculations were made, after which a strip template was made of tin. Using a template, the rotor was divided into equal parts. Then neodymium magnets will be glued between the risks.

8 magnets were used per pole. In total, there are 4 poles on the rotor. With a compass and a marker, all magnets have been marked for convenience. The magnets were glued to the rotor with “Superglue”. I will say that this is a painstaking business. The magnets are very strong, you had to hold them tight when gluing them. There were moments when the magnets came off, pinched fingers, and glue flew into the eyes. Therefore, you need to glue the magnets using protective glasses.

I decided to fill the cavity between the magnets with epoxy resin. For this, the rotor with magnets was wrapped in several layers of paper. The paper is secured with tape. The ends are plastered with plasticine for additional sealing. A hole has been cut in the shell. A neck is made around the hole made of plasticine. Epoxy resin was poured into the shell hole.

After the epoxy cured, the sheathing was removed. The rotor is clamped into a drill chuck for further processing. Sanding was carried out with medium grit sandpaper.

4 wires came out of the electric motor. I found a working winding, and cut the wires from the starting winding. I installed new bearings, since the old ones were spinning a little. The bolts tightening the body are also installed new.

The rectifier is assembled on D242 diodes, the “SOLAR” controller purchased several years ago on Ebay is used as a charging controller.

You can watch the tests of the generator in the video.

To charge the battery, 3-5 turns of the generator are enough. At maximum speed of the drill, 273 Volts were squeezed out of the generator. Alas, the sticking is decent, so it makes no sense to put such a generator on a windmill. Unless the wind turbine will be with a large propeller or gearbox.

The generator will stand on the ski lift. Field tests already this winter.
