Scrap metal collectors will be just happy to pick up your old washing machine. But do not rush to please them. You will get a little money for scrap, but if you approach this issue wisely, you can get a lot of useful things for the household. Homemade products from a washing machine engine will help you quickly clean a bird from a feather, cut pet food, mow a lawn, smoke fish and meat. And this is not a complete list of what can be made from a washing machine. Today, in the editorial review of the site, detailed instructions on how to give the “iron heart” from the washing machine a new life.

Parts from a washing machine - material for many useful homemade products

If you are going to make homemade products from a used engine, you need to figure out what it is and what it is capable of. In you can find three types of motors: asynchronous, brushless and collector. Let's take a closer look at them:

• Asynchronous– can be two-phase or three-phase. Two-phase engines are found in older models of Soviet production. More modern machines are equipped with three-phase. The design of such an engine is extremely simple, it can reach speeds of up to 2800 rpm. The working engine removed from the machine just needs to be lubricated - and it is ready for new exploits.

• Collector- you will find this type of motor in the design of most household appliances. Such devices can operate on direct and alternating current, are compact in size and have a controlled speed. The only drawback of such an engine is the washable brushes, but these parts can be replaced if necessary.

• Brushless direct drive- the most modern engine from a Korean manufacturer. You will find it in modern washing machines from LG and Samsung.

Now that you can determine the type of motor, it remains to decide where you can apply the motor from the washing machine.

We correctly disassemble and decide what can be made from the parts of an old washing machine

Dismantling a washing machine is a slow process. After working with water, salt build-up may remain on the parts, it must be carefully removed so as not to damage the parts during removal. What can be done from an old washing machine? A motor is useful for homemade products - it will become the basis for many devices. The drum will also come into play. It is usually made from stainless steel. All pipes must be disconnected from the drum. A loading hatch may also be useful. In addition to these parts, do not rush to throw away springs, counterweights and body parts.

How to make a grinder or grinder from a washing machine motor

A sharpener is one of the most popular tools for the home. With it, you can sharpen garden tools, household knives and scissors. If you don't already have one, buy one at any hardware store or make a grinder out of a washing machine. The most difficult moment is how to fix the emery wheel on the motor. The easiest way is to buy a ready-made flange. It looks like this.

You can carve a flange from a metal pipe of a suitable diameter, most often a tube with a cross section of 32 mm is suitable. From it you need to cut off a piece 15 centimeters long, this is quite enough to fix the emery. The flange is fixed to the motor shaft by welding or a through bolt. The video describes in detail how a do-it-yourself sharpener from a washing machine works:

We make a lathe for wood from a washing machine

What else can be done with the engine from the washer? One of the popular ideas is a wood lathe. Let's look at the step by step process.

Illustration	Action Description
	To firmly fix the engine on the workbench, make fasteners from a metal corner. To do this, drill holes for fixing to the motor legs and the table.
	To fasten a wooden part, you will need a flange fixed on the motor shaft, and these are the studs made from ordinary bolts with cut heads. Screw these pins into the base. You will need 3 pins.
	The motor is fixed to the table with self-tapping screws, to the metal part - with bolts.
	The opposite end of the wooden part is attached with such a device. It consists of a screw with a loop, two wooden stands perpendicularly fixed to the corners.
	This wooden part must be movable so that different blanks can be used. For mobility, it is mounted on a threaded stud with bolts.
	To control the motor, you need a power supply. You can use one of the computer blocks. You will need to install switches to adjust the rotation speed.
	How to connect the motor to the power supply in animation.
	To guide the tools, make a tooltip. It consists of two wooden parts and a metal corner. All parts are movable due to fastening with one bolt.
	The lower part of the handrest is rigidly fixed on the workbench using self-tapping screws and corners.
	The workpiece is fixed on the machine from two sides: on the left - on studs, on the right - on a bolt with a handle. For fixing in the workpiece, you need to drill the appropriate holes.
	To work, you will need sharpened tools - cutters.
	The final polishing of the workpiece is done with a strip of sandpaper.

How to make a simple removable machine for home use from a washing machine

The time of slaughtering a bird is a troublesome stage. This is usually done in the fall, when ducks and broilers have reached the desired weight, and it is no longer profitable to keep them in winter. You need to pluck several tens or even hundreds of carcasses very quickly. You can get rid of hard labor with the help of a removable machine, and it’s easy to make everything from the same washing machine parts.

For the device, you can not disassemble the washer. It is especially convenient to use machines with vertical loading. You just need to fix the beaters in the drum so that they look inward. Before plucking, the chicken carcass must be scalded with boiling water, and then simply thrown into a rotating drum. Here's what happens:

Important! To prevent water from getting on the engine of the pickup machine, you need to protect it with a plastic casing.

And the last point - the pen-removal device must be firmly fixed, since the vibration when loading the carcass will be very strong.

Used lawn mower

We continue to look for the answer to the question of where you can use the motor from the washing machine. Another original idea is manufacturing. For a small area, an electric model tied to a power source with a cord is enough. The device of such a unit is very simple. You will need to make a platform on four wheels with a small diameter.

The engine is fixed on top of the platform, the shaft is threaded into the hole below, and a knife is attached to it. It remains only to attach handles and a lever to turn the power on and off. If you have an asynchronous motor lying around, you will be surprised how silent the unit will turn out, even in comparison with factory models.

Advice! To prevent grass from wrapping around the knives, you need to slightly bend their cutting edges down.

Animal feed cutter

For a villager, a feed cutter is a very important device in the household. And this unit is easy to make from. What can be used: a drum and a motor.

For a feed cutter, you will need to make a housing in which a drum with holes sharpened for cutting and a lid for pressing will be attached. The connection of the rotating drum and the motor is carried out through the drive. The finished model looks like this:

How to assemble a generator from an old washing machine

We continue to consider homemade products from the motor from the washing machine, and the turn has come to the generator. You won’t be able to assemble a powerful device, but you can prepare well for the event of an emergency shutdown. To turn the engine into a generator, you will have to disassemble it and partially cut off the core. In the rest of the core, you need to make grooves for neodymium magnets.

The gaps between the magnets are filled with cold welding. For the device to work, the kit must include a motorcycle battery, a rectifier and a charge controller. Details of the work in the video:

Homemade concrete mixer

If you started a small repair, requiring, for example, plastering the walls, a concrete mixer will come in handy. And again, the parts of the washing machine come in handy.

As a container for concrete, you can use the same drum with pre-sealed holes for draining water. It is best to use parts from a front-loading machine, there is almost nothing to be redone. To strengthen the body, use a metal corner, and for convenient movement of the concrete mixer, equip it with wheels. The main difficulty in the design is the manufacture of a "swing" for the correct tilt and subsequent draining of the concrete. How to do it right in the video:

Homemade products from the engine from the washing machine: a circular saw

You will be surprised, but a circular can also be built on the basis of a washing machine motor. An important point in this matter is the additional equipment of the motor with a speed control device. Without this additional module, the circular will work unevenly and simply will not cope with the task. Device Assembly Diagram:

The principle of operation of the device is simple: the engine drives a shaft on which a small pulley is dressed. From the small pulley there is a drive belt to a large pulley with a circular saw.

Important! When working with a homemade circular, take care of your hands. All parts of the structure must be firmly fixed.

The resulting unit will not be very powerful, so it can only be used to dissolve boards up to 5 cm thick. How such a homemade circular works:

What else can be done from a washing machine drum: original decor ideas

The drum with its correct perforation is a material for making decorative items. Here are some interesting ideas.

Bedside tables and tables. In drums with a door from machines with vertical loading, you can hide the necessary little things.

We make a brazier from a drum from a washing machine, photo examples

- The item is temporary. Sooner or later it burns out and needs to be replaced. You can buy a new one every time or use improvised material, for example, a drum from a washer. Make this craft from a drum from a washing machine - a couple of minutes. The beauty is that oxygen easily enters the perforated container, which causes active combustion.

The metal of the drum will be able to withstand a couple of seasons. Make a comfortable stand for him so that you can not bend over, and you're done. Skewers of standard length will fit comfortably on a small brazier. If necessary, you can lightly weld a pair of guides by welding.

How to make a good smokehouse from a washing machine drum

Cherry on the cake in our question -. Fragrant smoked meat, bacon and fish - what could be better for the table? If you have a tank from a top-loading machine lying around in your barn or garage, consider it a hat.

In the bottom of the tank, it is necessary to cut a hole for the firebox, weld fasteners for hanging products inside. It remains only to install the tank on the hearth, hang fish or lard, cover the tank with a lid on top and set fire to the sawdust.

It is important that the fuel under the smoker smolder, not burn. Such a device is best located away from home.

Important! You will have to look after such a smokehouse. It cannot be left for a long time, the fire may flare up, and instead of smoked, you will get a burnt product.

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 loved ones 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.

It is not easy to acquire such a generator, since the work requires patience and some turning work. For it, they use a conventional asynchronous electric motor, which is available for automatic washing machines. It has a power of 170 ... 180 W; a generator made on the basis of such an electric motor will have 1.5 kW of power.

In addition to the engine itself, 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 remade in order to subsequently install magnets on it. The cores are removed and, placing them in a lathe, they are cut to a depth of 2 mm. Also arrange grooves of 5 mm depth.

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

The magnets are placed with equal gaps between each pair. If this is not done, then in the future they will stick together and the power of the generator will be lost. Placement of magnets is carried out on a strip of tin, which is first glued to the core with superglue. Do it evenly, excluding any slopes of the elements.

After the template with glued magnets is placed on the rotor, all the gaps that exist between the parts are filled with epoxy, cold welding. Next, the rotor surfaces are cleaned with sandpaper until smooth.

At the stator, they find wires that lead to the working winding. They are searched for with a multimeter. They have the same resistance. The rest of the wires are not needed 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 terminals of the multimeter are connected to the latter in voltmeter mode.

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

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

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.

The electric motor from the washing machine is very easy to find in view of the fact that it rarely fails compared to other components, and the machines themselves are thrown into the landfill all the time. The thing for do-it-yourselfers is very valuable, I take into account how many simple machines can be built on its basis.
This motor can also work as a generator. But unfortunately, just like that, it 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 engine from the washer has a classic structure of a collector electric motor. And it can work on both direct and alternating current. It's all about managing it.
Typically, the motor from the washing machine has 6 pins on the connection block: the first pair on top are the pins of the tachometer sensor, we won't need them to control the speed. The second two in the middle are the stator winding leads. The third lowest pair are the rotor leads.

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

We connect the wires to the stator. To the ends of the wires - a multimeter to measure the voltage at the output.

To show, 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 source. A 3.7 V lithium-ion battery will serve as it. Again, turn the shaft by hand.

The multimeter gave a certain value, which means that energy is being generated.
We change the 3.7 V battery to a 12 V battery. We rotate it by hand.

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

Drag, creating 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 instantaneous bursts of electricity.
For clarity, we will connect an incandescent lamp to 220 V. We will also wind the winch and pull it.

The lamp 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: gives out direct current, requires high speeds, requires additional power for operation, and if it stops, this power must be turned off somehow.
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.
