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 from the engine from washing machine 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 review of the editorial site detailed instructions 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. It can be used to sharpen gardening Tools, homemade 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. Most difficult moment- how to fix the emery wheel on the motor. The easiest way is to buy a ready-made flange. It looks like this.
The flange can be machined metal pipe 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 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. Important point in this matter - optional equipment 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 washing machine. 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.
Clean energy derived from natural resources, is one of the most popular topics today. Imagine that in your country house or country house there is a generator that feeds all the resources of your household with free electricity. It can be a wind turbine or a hydro 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.
One of these options based on a brushless DC motor, we want to present today. The author proposes to remount such an engine from a washing machine into a generator, soldering the leading stator coils in a special way. After such alteration, the engine can be used for a wind turbine. And if it is equipped with a water intake device like a Pelton turbine, then it is possible to build a hydroelectric generator.
Necessary materials and tools
As you probably already understood, today we only need the engine itself from the washing machine. The author used a DC inverter motor from the American Fisher & Paykel washing machine. Such engines are used in their products by LG, which is present in our domestic market.We will also need:
- Soldering iron, flux and solder;
- Hot glue;
- Fine-grained sandpaper - zero.
Starting to rebuild the engine
To work, it will be necessary to dismantle the engine from the machine body. It consists of three main parts:- Stator - a round platform with driving winding coils located along the outer edge of the circle;
- The rotor is a plastic or metal cover with a plastic core. Permanent magnets are placed along the perimeter of its inner wall;
- Shaft - central part motor, equipped with bearings to transfer kinetic energy to the drum of the washing machine.
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 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. We cut each of the 6 coil outputs with wire cutters according to the diagram.
The cut edges must be bent with a screwdriver or by hand, so that it will be more convenient to work with them later.
We clean each contact with fine-grained sandpaper to improve soldering.
When everything is ready and cleared of debris, we connect together every second group of three contacts. Strengthen hand twisting with pliers.
With a soldering iron, we tin the twist with the help of a flux, and solder it with tin solder. We open the twist, and solder it from the back. We do the same with the rest of the contacts. As a result, we should get seven twists.
Phase loop
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 multicore cable. We mark and cut it to the size of the inner circumference of the platform.
We expose the insulation at the junctions with free contacts, and clean them with sandpaper. We begin to solder the ring from the contact group, passing each of the seven, ending with the last contact. For a reliable 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 to each other.
Homemade products from the engine from the washing machine (video selection, photos, diagrams)
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!
2. Homemade emery from the engine of a washing machine
Today we are going to talk about transformation. asynchronous motor from the washing machine to the 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.
By measuring the circumference of the resulting rotor, were produced necessary calculations, 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. Poured into the hole in the shell epoxy resin.
After the epoxy cured, the casing was removed. The rotor is clamped in the chuck drilling machine 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.

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.
it good decision 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 important an environmental problem as pollution. environment combustion products 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, and then into electrical. We recommend that you look at the article about and its principle of operation.
Largely modern models equipped with three blades to increase efficiency and start working when the wind speed reaches at least 2-3 m/s.
Wind speed - 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 wind generator power of 20 kW.
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.
Problems with electrical energy, which usually arise unexpectedly, force many consumers to think about the device of an autonomous power supply. Moreover, exorbitant bills for the use of the industrial network are also pushing for this. Installing an autonomous power source in the house is considered a profitable business. This device is able to come to the rescue when the industrial power supply is switched off.
Its power indicator is relatively small, but this is quite enough to act as a backup power source. Purchasing a generator on purpose is an expensive pleasure, but making it yourself is quite realistic. Today we will consider how to make a generator from a washing machine engine with your own hands.
Preparatory work
It seems to many that to make homemade electric generator from is a simple matter. Drop all illusions, because you will not be able to quickly cope with such a task. First of all, three main problematic issues should be dealt with:
- how to remove part of the core of the electric motor from the washing machine, arrange special grooves on it designed for magnets;
- where to get neodymium magnets in the generator rotor;
- what material to use to make a template to secure the magnets.
- The first question is answered in the following way: induction motor the spent washing machine, the core is removed, which is cut two millimeters deep using a lathe. After such refinement, we put the engine aside - we will have to look for neodymium magnets, and it is best to use the help of the Internet. Having found the store, you should apply for the purchase and wait until the right product is delivered, since the device cannot be made without magnets.
- On the machine, we prepare grooves in the motor core for magnets, their depth must be at least five millimeters. You will need good lathe skills, or seek help from a specialist.
- After spending preparatory work on the core, we prepare mounting templates for magnets. You can use a piece of tin, other materials with similar properties will do. The strip is cut to the appropriate length and width so that it can fit exactly on the core.
- The mounting strip will also have to be prepared, for which markings are arranged along its entire length in order to place the magnets in two rows in such a way that the distance between these magnets will be the same.
- As additional materials for the conversion into a generator device, we need superglue, epoxy or cold welding, sandpaper.
Having prepared everything you need, we can begin to work. We immediately warn you that it will take a lot of patience to make the desired element from the washing machine engine. Magnets will constantly jump off and stick to each other, you will smear everything with glue, so we recommend that you use caution and safety requirements when working with potentially harmful chemical compounds.
The algorithm of actions is as follows:
- we make a magnetic rotor of an electric motor in order to convert it into a generator. We glue tin templates across the engine for placing magnets;
- according to the previously applied markings with the help of superglue, we fasten two rows of magnets;
- all the free space remaining between the magnets is carefully filled with cold welding, previously kneaded by hands to a plasticine consistency;
- grind the device with sandpaper. To make it more convenient to work, it is recommended to fix the case in a drilling machine.
The process of manufacturing a generator from an engine is completed, it remains to test it in action. To perform the check you will need:
- rectifier;
- multimeter;
- charging controller;
- motorcycle battery;
- homemade electric generator.
Think about how the rotation will be carried out. You won’t be able to do this with your fingers, because you won’t be able to create the required number of revolutions. We recommend using an electric drill or screwdriver.
We determine a pair of working wires on the prepared device, cut off the rest. We connect the wires through the rectifier to the charge controller, and then to the battery. We fix the fasteners of the multimeter on the battery terminals - the generator is ready for testing.
We charge the generator pulley into the cartridge of the power tool, with the help of which the promotion will be performed, and give revolutions in the range of 800 - 1000 rotations. As a result, with moderate sticking of the magnets, 270 volts should be obtained, which will turn out to be quite an acceptable indicator.
What is the best way to use such a device? If you install a generator on a chainsaw, you get a small power plant, the energy of which will be enough to light two small rooms, start your computer and even watch TV.
It is possible to connect the generator to a hydro turbine installed in a domestic waterfall or fast-flowing stream.
Some install wind turbines and generate electrical energy from the mechanical energy received. For this, generators are suitable not only from an asynchronous, but also a collector motor. An alternative power source is quite safe, able to start at a wind speed of two to three meters per second. But with ten-meter gusts of wind, such a generator will reach its maximum efficiency, although four meters will be enough for home consumption, allowing it to generate 0.15 - 0.20 kW, which will be quite enough to light the room and watch TV.
At 1 - 5 kW, feel free to turn on the computer, refrigerator and even the washing machine. But 20 kW will already be enough to supply heat to the heating system.
It is best if the windmill you install turns out to be three-bladed - as it is the most efficient in operation. Use a steel bar as its basis, on which you attach the generator, blades and rotor. Consider protection for the generator so that it does not suffer from adverse weather conditions. For the moving part of the wind turbine, provide a hinged mount. We lay a wire from the generator along the length of the mast, bring it to the shield, connect the controller, inverter and battery device. As you can see, the connection diagram is simple.
Conclusion
With patience, you can independently make an electric power generator from the electric motor of an old washing machine, which will come to your aid in difficult times. Besides, with such a home-made installation, you can start saving money on utility bills.
