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

Not all "washer" motors will work with a capacitor.

There are 2 main types of engines:
- with capacitor start (constantly switched on capacitor)
- with starting relay.
As a rule, "capacitor" motors have three winding outputs, power 100 -120 W and revolutions 2700 - 2850 (motors of centrifuges of washing machines).

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

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

Today we will talk about the conversion of an asynchronous electric motor from a washing machine into a generator. In general, I have been interested in this issue for a long time, but there was no particular desire to remake 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. Having your own lift is a good thing, but riding with music is much more fun, so I quickly got the idea to make such a generator so that I can use it on the slope in winter to charge the battery.

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

Looking ahead a little, 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.

The electric motor of a washing machine with a capacity of 180 watts, manufactured in China in the early 90s of the last century, was taken as a basis.

I ordered magnets from NPK Magnets and Systems LLC, before I had already bought magnets during the construction of a wind farm. Neodymium magnets, magnet 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). Neodymium magnets will be installed in the resulting recess. At the beginning, 2 mm of the core was removed on a lathe - a protrusion above the side cheeks. Then a 5 mm recess was made for neodymium magnets. The result of the alteration of the rotor 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 from tin. Using a template, the rotor was divided into equal parts. Neodymium magnets will then be glued between the risks.

8 magnets were used per pole. In total, 4 poles turned out on the rotor. With the help of a compass and a marker, all the magnets were marked for convenience. Magnets were glued to the rotor with “Superglue”. Let me tell you, it's hard work. The magnets are very strong, I had to hold them tightly when gluing. There were moments when the magnets came off, pinched fingers, and glue flew into the eyes. Therefore, you need to glue magnets with the use of goggles.

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

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

There are 4 wires coming out of the motor. I found a working winding, and cut off the wires from the starting winding. I installed new bearings, because the old ones rotated a little tight. The bolts tightening the body are also new.

The rectifier is assembled on D242 diodes, the SOLAR controller, bought a few years ago on Ebay, is used as a charging controller.

Tests of the generator can be viewed on the video.

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

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

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 improvised means (washing machine, scrap metal, broken household appliances) with your own hands.

A wind generator is a complex of mechanical devices related to an alternative source of electricity that converts the kinetic energy of the wind into mechanical energy using blades, and then into electricity.

Modern models have three blades, this provides a greater efficiency of the installation. The minimum wind speed at which the windmill starts is 2-3 m / s. Also, the technical specifications always indicate the nominal speed - the wind indicator at which the installation gives the maximum efficiency indicator, usually 9-10 m / s. At wind speeds closer to 25 m/s, the blades take on a perpendicular position relative to the wind, due to which energy production drops significantly.

In order to provide a private house with electricity, with 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 basic electrical appliances (refrigerator, washing machine, computer, iron, etc.) and lighting;
• 20 kW will provide energy for the whole house, including heating.

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

The main parts of the wind generator

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

• Rotor - 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 drill generator).
• Blades. They are usually made of wood, light metal (aluminum), or plastic. They can be sail type (like a windmill) and winged.

Advice! Vane profile blades are more efficient.

• A generator is a device that converts wind power 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 to orient the windmill in relation to the wind. It is made of wood, light metal, plexiglass or plastic.

• Horizontal yard to support the generator, wind turbine and tail.
• A mast on which a yard with a generator is movably attached. It reaches a length of 5 m to 20 m and is made of durable wood or a plastic/iron tube hollow inside with a box for the outlet of the electrical wire. It is fixed with steel cables for additional reliability.

Advice! The higher the matcha of the windmill, the more energy it will generate.

• 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 windmill generator from a washing machine

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

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

We make the holder, axis and blades

How to install a wind generator

• We install a generator, blades, rotor and tail on the carrier rail. At the same time, it is necessary
  close the generator and the windmill rotor with a special casing for weather protection.

Advice! To protect against cold, the unit can be coated with a silicone-based lubricant.

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

• 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, charging for your 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 homes in the absence of light. In order to make it yourself, you need to have basic knowledge in electrical and electronics. It is advisable to watch the video instruction for more information.

Wind turbine from a washing machine motor: video

An old washing machine is a real Klondike of spare parts for a home craftsman. And the desire to give them a second life is quite understandable - for example, to design a wind generator. A simple and useful device will partially solve the problem of power supply for a small object: a country house, an outbuilding for tools or a workshop. Especially since:

• The cost of the cheapest Asian-made wind turbine model from Aliexpress is several tens of thousands of rubles. And no one can guarantee that you will be sent a serviceable and powerful device.
• A do-it-yourself wind generator from a washing machine will cost no more than 5000 rubles. The price includes all the necessary consumables, provided that you already have a faulty machine that you want to find a worthy use.

Please note that some mechanical and electrical knowledge is required to successfully assemble the device. But the output will be quite 2 - 2.5 kW, completely ready for long-term operation in the Russian climate. A couple of rooms, a small PC or a TV - the power of the device is quite enough to supply them with energy, moreover - completely free.

We select materials

The basis of the future design is the electric motor of the washing machine with a power of at least 1.5 kW. We are talking about a serviceable design, and not a burnt motor. You will also need:

• A rotor with blades that will rotate due to the force of the wind. The design of the blades is easy to make with your own hands from improvised materials: plywood, sheet metal, etc.
• A set of neodymium magnets - 32 pcs. 0.5, 1 or 2 cm.
• Reducer, "responsible" for the speed of rotation of the generator.
• A protective cover that excludes any climatic influence on external structural elements.
• A battery that carefully collects and accumulates energy for the operation of household appliances in a calm period.
• Inverter for transforming direct current into alternating current.
• Mast for installation of a structure in an open space.

If you decide to surprise your relatives with a wind generator made from a motor from a washing machine, do not rush to the nearest market for shopping. Most of the listed devices and materials are easy to find in old household appliances that are out of use and gathering dust in the basement or on the balcony. This saves you time and further reduces the cost of the future generator. The exception is neodymium magnets, which are better to order on Aliexpress or in ordinary stores selling electrical equipment and radio products. Tools that should be at hand during work: a screwdriver, scissors and pliers, as well as a drill or screwdriver, which will play the role of wind during testing of the device.

Cores are removed from the motor rotor, on which grooves are cut 5 mm deep. Then the cores are covered with a tin coating and proceed to the laying of neodymium magnets. First, they must be marked and then - sequentially laid out on a strip of tin, taking into account the mutual attraction of neighboring magnets. Fastening is carried out using a suitable superglue, which guarantees a reliable connection of metal elements.

Please note: when constructing a windmill from a washing machine engine, it is important to observe the distance between adjacent magnetic elements. The attractive force of neodymium magnets is so strong that even fastening with superglue will not be able to hold them in place. And the adhesion of elements will negatively affect the working capacity of the new generator.

You will have to work hard to create an impeller with a shank and blades. The main thing is that they rotate easily under the influence of the wind. An excellent solution would be fiberglass - a dense and lightweight material that is durable and not afraid of the climatic difficulties of the Russian weather.

After laying and gluing, the tin sheet with magnets is placed on the rotor, filling the gaps with cold welding or epoxy. The final grinding of the surface with sandpaper - and the generator frame is completely ready.

For a wind generator from a pump from a washing machine, a vertical gearbox is recommended. Its main advantage is the ability to rotate freely on the mast along with the paddle design. Of course, the weight of the additional device will slow down the rotation speed somewhat. On the other hand, the gearbox, which limits the number of revolutions of the blades, will “take care” that the propeller does not fail during a hurricane.

According to the diagram below:

• the main gear 5 is put on the mast 7;
• reinforcing segments C are welded in a circle;
• bearings with gears B are put on fittings;
• small gear A is in contact with gears B;
• gear B is in contact with the teeth of the gearbox housing 11.

Checking device performance

The two wires leading to the motor winding are connected to the rectifier, and the rectifier is connected to the controller to which the battery is connected. Using a drill or screwdriver, the device is put into operation at a speed of about 1000 rpm. The voltmeter probes are connected to the battery and the resulting voltage is measured. An indicator of 200-300 V indicates the excellent performance of the device.

Please note: if the voltage level is low, a mistake was probably made when installing the magnets. If you are determined to achieve the goal and assemble a working generator, the device will have to be redone or made in a new way.

Making a mast for installing a wind turbine

A high mast will help to securely install a wind generator from a pump from a washing machine. The optimal solution is steel pipes with a diameter of about 32 mm, relatively light and durable. Several segments connected in series by welding will easily turn into a high mast about 10 m long. It is painted white or another light color and fasteners are mounted from the corners, which securely hold the structure in a vertical position. The finished mast can be placed on an “unnecessary” lighting pole or other free pole that was once installed, but has not yet found a worthy use for it. In the absence of a pole, you will have to independently think over and make a support for the mast that can withstand the weight of the working structure.

Electricity is an expensive resource, and its environmental safety is in doubt, because. hydrocarbons are used to generate electricity. This depletes the subsoil and poisons the environment. It turns out that you can provide the house with wind energy. Agree, it would be nice to have a backup source of electricity, especially in areas where power outages are common.

The conversion plants are too expensive, but with some effort you can assemble them yourself. Let's try to figure out how to assemble a wind generator with your own hands from a washing machine.

Next, we will tell you what materials and tools will be required for the job. In the article you will find diagrams of a wind generator device from a washing machine, expert advice on assembly and operation, as well as videos that clearly demonstrate the assembly of the device.

Wind turbines are rarely used as the main sources of electricity, but as an additional or alternative they are ideal.

This is a good solution for cottages, private houses located in areas where there are often problems with electricity.

Assembling a windmill from old household appliances and scrap metal is a real action to protect the planet. Garbage is just as urgent an environmental problem as environmental pollution by products of combustion of hydrocarbons.

A home-made wind generator from a screwdriver or a washing machine engine will literally cost a penny, but it will help save decent amounts on energy bills.

This is a good option for zealous hosts who do not want to overpay and are willing to make some efforts to reduce costs.

Often, car generators are used to make windmills with their own hands. They do not look as attractive as industrial production structures, but they are quite functional and cover part of the electricity needs.

A standard wind generator consists of several mechanical devices, the function of which is to convert wind kinetic energy into mechanical energy, and then into electrical energy. We recommend that you look at the article about and its principle of operation.

For the most part, modern models are equipped with three blades to increase efficiency and start working when the wind speed reaches at least 2-3 m / s.

Wind speed is a fundamentally important indicator on which the power of the installation directly depends.

The technical documentation for industrial wind turbines always indicates the nominal wind speed parameters at which the installation operates with maximum efficiency. Most often, this figure is 9-10 m / s.

What energy costs can the installation cover?

Installing a wind turbine is cost-effective if the wind speed reaches 4 m/s.

In this case, almost all needs can be met:

• A device with a power of 0.15-0.2 kW will allow you to switch room lighting to eco-energy. You can also connect a computer or TV.
• A wind turbine with a capacity of 1-5 kW is enough to ensure the operation of basic household appliances, including a refrigerator and a washing machine.
• For autonomous operation of all devices and systems, including heating, you need a 20 kW wind generator.

When designing and assembling a windmill from a washing machine engine, wind speed instability must be taken into account. Electricity can disappear at any second, so the equipment cannot be connected directly to the generator.

Electricity is a rather expensive source, whose environmental safety is in doubt. This is due to the fact that hydrocarbons are used to produce electricity. These processes not only consume subsoil, but also poison the environment. You can provide the room with wind energy. Such installations are not cheap, but you can make a wind generator from a washing machine engine with your own hands.

Such devices are rarely used as the main sources of electricity, but as additional ones they are quite optimal. This is ideal for summer cottages, country houses, which are located in places where power outages often occur. A home-made design from the engine of a washing machine or a screwdriver will be very cheap and will help save significant amounts on energy costs.

This is a great solution for thrifty hosts who do not want to overpay and are willing to work hard to reduce costs. The classical design includes mechanical devices, the main purpose of which is the conversion of the kinetic energy of the wind into mechanical, and then into electrical. The majority of modern models are equipped with three blades. This is necessary to increase the efficiency. They begin to function at a wind speed of 2–3 m/s.

Wind speed is the most important indicator, because the performance of the unit depends on it. In the technical documents for industrial windmills, indicators are always indicated at which the product operates with maximum efficiency parameters. In most cases, this value is 9−10 m/s.

There are also maximum allowable wind speeds. They vary between 23−25 m/s. With such indicators, the efficiency of the wind generator is significantly reduced, because the blades of the unit change position. If we talk about a self-made installation, it is extremely difficult to calculate the technical characteristics in it.

It is necessary to focus on average values, and then calculate the right amount of electricity for basic needs.

Unit profitability

Installing a wind turbine is justified if the wind speed exceeds 4 m/s. In such a situation almost all needs can be met:

1. A product with a capacity of 0.15-0.2 kW will be able to convert the lighting of the premises to environmentally friendly energy. In addition, it will be possible to connect a TV or PC.
2. A design with a power of 1-5 kW will be able to ensure the functioning of appliances, including a washing machine and a refrigerator.
3. For the operation of all systems and equipment on environmentally friendly energy, including heating, a unit with a capacity of 20 kW is required.

When making a wind generator from a washing machine with your own hands, you should take into account the instability of the wind speed.

Electricity can disappear at any time, so household appliances should not be connected directly to the appliance. This requires batteries and a device to control the charge, since electrical equipment requires a voltage of 220 V.

To make the unit with your own hands, you will need to buy a few parts. Many of them can probably be found in old household appliances, but some will need to be purchased. Main elements:

If you purchase a ready-made station, along with the installation you need to pay 70-80 thousand rubles. A home-made wind generator will cost no more than 3.5-4 thousand rubles.

The difference in cost is significant, so it is quite advisable to make and install the structure on your own. The result is a unit with a power rating of about 2.5 kW. This is quite enough for the functioning of household appliances.

Principle of operation and types of products

All wind turbines are different, regardless of whether they are industrial or do-it-yourself. Their classification is carried out on several grounds:

With the independent production of a windmill, you first need to decide on the design. In addition, it is necessary to calculate the required power taking into account the operating conditions.

Horizontal structures are more preferable because their production does not require high-precision calculations. Such a windmill is much easier to make, it starts to work even with a small wind. The disadvantage is the bulkiness of the product and noise during operation.

The vertical unit is suitable for those who have time to assemble and install a complex but compact system. The windmill operates by moving the blades that are attached to the rotor. The latter is fixed on the generator shaft, which generates a flow of electricity. Further, the energy is supplied to the battery devices, where it accumulates, and then supplies power to household appliances.

Advantages and disadvantages

Windmills have been popular for a very long time. Designs are constantly being improved, and the wind is an easily accessible energy source. Devices powered by it are environmentally safe and convenient, because they are placed on masts without occupying usable space. The units are easy to maintain and repair.

Structures emit sound during operation. The noise may be louder or quieter, but it is always present. Often this aspect interferes with the owners of the house and neighbors. There are other disadvantages as well.

Wind is an extremely unpredictable element. Because of this, the activity of the generator is unstable, so you need to accumulate energy so that in calm weather you will not be left without electricity.

Manufacturing instructions

For the production of a wind generator, you will need an engine from a washing machine with a capacity of 1.5 kW. Besides, you will need:

• neodymium magnets 0.5-1.2 cm in size - 32 pcs.;
• sandpaper;
• epoxy resin;
• glue.

Magnets can be bought in online stores or retail chains. They need to be installed on the rotor. From the latter, it is necessary to remove the cores or cut off part of them on a lathe. Then they make grooves with a depth of 5 mm.

When the design is ready, it is necessary to install the magnets in the places provided. First of all, a tin coating is made for the core, and then the magnets are installed at the same distance from each other. It is important to observe the distance, otherwise the magnets will stick together during operation, and the performance of the device will be significantly reduced.

The finished magnetic template is placed on the rotor, and the gaps are filled with epoxy. When the procedure is over, clamp the rotor in a vise and carefully sand the surface with sandpaper. After that, the condition of the bolts on the bearing and housing should be checked. If the elements are worn out, it is recommended to replace them.

Health check

To check the operation of the assembled wind generator, you will need additional devices. Among them:

• rectifier;
• tester;
• battery;
• controller.

First of all, you need to determine which wires come from the working winding, and remove all the rest.

These conductors must be connected to the rectifier. The latter is connected to the controller, which is connected to the battery. The system is ready for testing.

The power of the windmill is checked as follows: a voltmeter is brought to the battery, and the assembled unit is spun with an ordinary drill or screwdriver. It should be noted that the speed of the latter should be at least 800 rpm, the best option is 1000. 200-300 V is considered normal.

When assembling a wind turbine from a washing machine, it may be difficult to manufacture an impeller. You need to choose a lightweight, but at the same time durable material. A good solution is fiberglass blades. They are light in weight, but very reliable and durable. For the mast, steel pipes with a diameter of 32 mm are sufficient.

Installation process

The first step is to choose a suitable place for the wind generator. It is desirable to install the support in an open area, the top of the hill is best suited for this. Many experienced craftsmen believe that the higher the supporting structure, the better. Step by step:

To protect the wind turbine from various weather conditions, you can make a canopy over it. Such designs significantly increase the operational life of the product.

Experts do not advise immediately connecting expensive and powerful household appliances to the windmill. First you need to test the design on a phone charger or other simple devices.

A wind generator is the best option as an alternative source of energy, but it can also become the main one for small buildings or country houses. A homemade device will work for more than one year. In addition, a hand-made product will significantly save the family budget. The main thing is to carefully study the information and not be afraid of experiments.
