At the flea market, engines from Soviet-era washing machines or even from modern products often come across. Such an engine is usually not expensive, but there can be a lot of benefits from it.
The idea is to make a grinder out of it, the performance of which can be even better than that of the Chinese counterpart. However, before buying, it is advisable to check the performance.
First, we measure the resistance of the working and starting windings. The starting winding is of the greatest importance. We begin the production of a frame for our future machine. It must be stable and durable.
To form the frame, a metal corner and a profile pipe are used. Pieces are cut. The engine is installed on a part of the frame, and then the body is assembled around it completely by welding. Next, we make a table to the frame from the same profile pipe, cutting it in half.
Main stages of work
We weld a pair of pieces of round timber, forming a uniform gap between them and the nuts along the edges. Under the table you need to make an emphasis. Then we make an additional part to fix the required angle, which can be adjusted.
We take a disc from an old pneumatic grinder with a diameter of 150 mm. We cut the threads on the motor shaft and on the disk itself under the adapter from the elongated nut. If the motor is capacitor, and its power is 180-200 W, we connect a starting capacitor of 12 microfarads (at the rate of 7 microfarads per 100 W).
We fasten one end to the motor wire, the other to one of the wires of the network cable. We place the capacitor near the engine with the help of screeds. Soundly isolate all contacts and fix the network cable to avoid displacement.
For the convenience of moving the machine, you can make a handle from a polypropylene pipe, inside of which there is a metal rod. It is attached to the engine itself. We assemble the entire structure, install the disk and start our machine into operation.
After just a few years, I want to replace them with newer and “fancy” ones. But it’s a pity to throw away old equipment that is still working. Therefore, it can be given a "second life". Very often, a washing machine acts as the basis for homemade products. Absolutely all elements can be used from it: engine, wiring, body, drum, legs. But the most common homemade from the engine from washing machine.
What can be collected?
Homemade products from a washing machine engine are used in household. They greatly facilitate many types of work. In particular, the following devices are assembled:
- Electric emery, which is necessary for sharpening knives, drills, tools and so on.
- A lawn mower that allows you to mow the grass in your summer cottage.
- Feed chopper that cuts greens into small pieces.
- Concrete mixer.
- Wood splitter.
- Potter's wheel.
- Lathe.
- Generator.
This is far from full list what can be collected from the engine from the washing machine. In fact, there can be a lot of ideas. Fans of tinkering with electronics come up with new and interesting homemade ideas from the engine from the washing machine. Therefore, we will dwell on only a few examples in detail.
Emery
One of the most popular homemade products from a washing machine engine (automatic or semi-automatic - it doesn’t matter) is an electric knife.
The first step is to prepare the flange. Its necessity is due to the fact that the shaft from the motor has one diameter, and the hole of the grindstone has another. One side of the flange will be pressed onto the motor shaft. On the second side, a thread is needed to secure the circle. Most often, a metal pipe 15-20 cm long and 32 mm in diameter is used to make a flange.
Particular attention must be paid to carving. Its length should be more than the thickness of the circle, about 2 times. It is also important to choose the right direction. The thread must be directed in the opposite direction from the direction of movement of the shaft. If the shaft rotates right side, then the thread is cut to the left. And vice versa. This is done so that the circle does not fly off during operation. Moving in opposite directions, the circle will twist.
The second end of the flange (which is not threaded) is pressed onto the motor shaft. To do this, it must be heated with a blowtorch. To obtain a stronger connection, the junction is connected by bolts or welding.
A nut is screwed onto the edge of the threaded flange until it stops. Next, a washer and a circle are put on, which is fixed with a washer and a nut on the other side. When everything is tightly tightened, the lock nut is screwed on.
The whole structure is fixed on a stand. Moreover, the fastening must be very reliable and durable so that the structure does not move during operation. After that, the engine is connected to the network.
lawn mower
Popular homemade products from the washing machine engine are lawn mowers.
As a basis, you can take a frame from a stroller or cart. If there are none, you can make a frame from metal corners. A metal sheet is attached to the finished frame, which will play the role of a platform. A protective mesh is attached to the platform in front. Handles are made from pipes. A rubber casing is put on top of it.
The engine is mounted on a platform. In the center of it, a hole is being prepared for the shaft to which the knife will be attached. The motor is connected to a cable with a plug (or switch). To comply with safety regulations, the plug with a socket is placed on the handle.
Feed chopper
The popularity of homemade products from over time only grows. Recently, more and more feed cutters are being made. This also requires a drum.
4 holes for bolts are made in the walls of the drum. With their help, the structure will be attached to the support frame. On one side of the drum, a hole is made for the shaft. On the other - for unloading the finished feed. Two knives are used. One is installed at the bottom of the drum. He has to throw up food. Therefore, its shape should resemble a propeller. The second knife, sharpened on both sides, will be the main one. It is tilted towards the bottom.
To prevent food from flying around, a lid is made. It is necessary to make a hole in it through which the feedstock will be fed.
As you can see, homemade products from the engine from the washing machine are widely used in the household.
Your favorite washing machine has already lived its life, and you decide to send it to the trash? Do not rush, because you can create various homemade from the engine from the washing machine.

Spare parts
The automatic washing machine has a rather complex design. Even in the event of a breakdown, it will contain the spare parts necessary for the manufacture of some homemade products. Let's see what can be done from the parts of an old washing machine.
The main part, of course, is the engine (motor). If it is serviceable, then it can be used to make a generator, sharpener, lawn mower and other appliances. Carefully disconnect the wires, remove the motor from the body of the washing machine and save it.
The manhole cover can be turned into an unusual window or into a beautiful bowl for feeding pets. You can also make a case for counters from durable glass.
Legs, springs and other small details are useful for the construction of various homemade products. The case itself can become a cabinet or a unique table.
Let's take a closer look, what can be done with the engine.
Washing machine motor prices
washing machine motor
Types of motors
Asynchronous
The oldest type of engines, consisting of stationary stator and rotating rotor. The first serves as the basis and magnetic circuit for the structure, and the second creates the driving force of the drum. The entire motor is driven by an alternating magnetic field of the component parts.
Asynchronous motors have low torque, therefore, the drum often wobbles during operation. Other disadvantages - dimensions and modest efficiency. At the same time, they are silent, are cheap, have a simple design.
The induction motor is often found in cheap, low power appliances.
There are two- and three-phase asynchronous motors. The former are long out of production and can only be found in very old structures.
Collector
The most common type of engine. Works great under both AC and DC voltages. under the body with hidden rotor, stator, generator providing rotation speed. Special brushes are located on the collector terminals, with the help of which the rotor contacts the engine.
Note: If you connect the rotor and stator directly, the motor shaft will rotate clockwise. For the opposite direction, you need to change the connection diagram of the electric motor of the washing machine - connect the brushes towards the rotor.
Unlike their oversized predecessor, brushed motors are quite compact and have a high rotational speed. They are universal: it works with both alternating and direct current. Main disadvantage commutator motor - low wear resistance: due to the constant contact of the brushes with the commutator, both the brushes and the commutator wear out quickly. If the former can be easily replaced with new ones, then replacing the collector will cost a lot of effort.
inverter
Most modern look motors washing machine consists of a rotor and a stator. Unlike other types, the rotor of the inverter motor is directly connected to the drum. They are distinguished by high wear resistance, the absence of unnecessary parts, simple design, noiselessness, small size.
However, all this in one motor is not a cheap pleasure: the development, production, and, consequently, the purchase of an inverter motor requires large financial costs.
Connection
To connect the engine to a 220-volt network, you must have a tester at hand: it will help us break the wires into pairs, and also measure the resistance in the windings.
Before connecting new models, you need to determine with a tester the wires that out of the tachogenerator and will not be needed during operation. Finding them is quite easy - just measure their resistance: it should be about 70 ohms.
Using the same device, we find pairs of other contacts. Now we connect one of brushes to one of the wires, and the second brush and the other wire are connected to the outputs of the winding. After connecting the motor from the washing machine to the mains, the appliance will begin to rotate. To change the direction of rotation, just swap the brushes.
With older models, the situation is a little different: after determining the paired outputs, you need to determine the working and exciting windings. The first has more resistance than the second.
We figured out how to connect the motor from the washing machine to the network. Now let's see what machines and devices you can create yourself with it.
Homemade
Homemade products from the motor are quite diverse: with it you can create t sharpener, lawn mower, concrete mixer, juicer, potter's wheel and much more. Consider the manufacturing process of some of these devices.
Emery
One of the most common uses for an old engine. Assembling the machine does not require much effort. The hardest part of the job is attaching the grindstone to the motor. The fact is that the diameters of the shaft and the stone are different from each other, therefore to connect them you need a third item. A piece of a metal pipe about 20 cm long is perfect. A thread is cut at its end, the length of which is 2 times greater than the thickness of the grindstone.
It is necessary to cut the thread in the opposite direction of movement of the motor shaft. At the other end we attach the shaft with a soldering iron.
For greater reliability, you can drill at the connection point hole and screw in the bolt. and a nut. We alternately screw two pairs of nuts and washers onto the flange threads, and finally we tighten the lock nut.
We fix the engine on the stand. Both an old table and a piece of thick board can serve as a stand. For fixing, you can use fasteners from the same washing machine from which the engine was removed.
Wood lathe
The power of the old engine is enough for slow processing of a cylindrical workpiece . To save the motor from side loads, you can attach a support to it.
drum sander
It is made using a large wooden cylinder with a steel bar in the center. The ends of the bar are connected to the motor chuck and bearing stand.
Concrete mixer
Old washers, or "barrels", easily turn into a compact and practical concrete mixer. For this:
- We take out the activator from the car.
- Cut out from sheets steel 4-5 mm thick blanks for the manufacture of blades.
- We weld a pair of U-shaped blades, connected at right angles.
- We weld them in place activator.
Homemade concrete mixer will work after you connect the engine from the washing machine to the mains. If the machine will be used to work with small volumes of building materials, then the power of the old engine is quite enough. For larger volumes, it is recommended to connect a more powerful motor.
feed cutter
For the manufacture of a feed cutter-grain crusher, you will need a “barrel” body and an engine from an automatic machine:
- At the bottom of the case create a hole through which the finished feed will exit.
- Similar to a concrete mixer create blades with knives. Need to pick for them suitable size: there should be a small distance between them and the edges of the case.
- Installing the blades: one at the bottom of the case, and the other at a distance of 0.5 meters from its top. To achieve greater homemade performance, it is recommended to use a separate shaft for each blade so that they rotate in opposite directions.
- Remains only cut holes in the lid, through which we will fall asleep raw materials.
lawn mower
Let's move on to more complex and extravagant designs. First on our list is a lawn mower. By making a homemade lawn mower, you will save a huge amount of money, because these simple machines are quite expensive. If you do it right, then a home-made lawn mower from an engine from a washing machine will not be inferior to appliances on store shelves.
First, let's figure out what materials and tools we need:
- commutator motor;
- compact but strong wheels. These can be removed from strollers, toy cars. If these are not available, cut the wheels out of the plastic profile;
- for the base you will need a thick piece of steel or plain saucepan lid;
- knives, disks;
- metal pipe;
- steel corners;
- copper wire, plug;
- switch;
- fixing materials;
- open-end, end, keys;
- welding machine, grinder;
- a hammer;
- drill, screwdriver, pliers;
- soldering iron.
Let's get to work:
- At the center of the base cut holes for the motor shaft. Install it upside down.
- We attach earlier bushing on the shaft, and we attach a disk (knife) to it.
- From the corners we assemble the frame for the motor.
- We weld the handle, fix the switch to it
- We connect the engine to the power supply.
be careful: Unlike factory appliances, the wires of our homemade lawn mower are not insulated. It is strictly not recommended to use such a device during rain or for cutting wet grass.
If you still want your machine to be operated in any weather, then securely insulate the wires, and for the device assemble a small casing made of waterproof material. A metal bowl is suitable as a casing.
Generator
Tired of unexpected power outages? Do you want to create redundant power supply who will help you out at the right time? So why not create a generator from an engine from a washing machine with your own hands? The assembly process is quite complicated, but the result is worth it.
The basis for the future generator will be an asynchronous motor. Before creating the generator, let's do some preparatory steps:
- Dismantling the motor housing. Using a lathe, we make a cut on its core with a depth of 2 mm.
- In pre-prepared grooves on the core insert neodymium magnets.
- We create a template for attaching magnets from a tin strip. We mark on it the placement of two rows of magnets.
The dimensions of the strip must exactly match the dimensions of the core: the tin must lie tightly on it.
The preparation is completed, we proceed to the assembly itself. We will need:
- sandpaper;
- cold welding;
- glue;
- rectifier;
- tester;
- battery;
- charge controller.
The build sequence is:
- We glue the template on the motor. We glue magnets on the template itself.
- Please note that the distance and angle between the magnets do not change. Otherwise, voltage drops, power reduction or its complete inoperability are possible.
- Free space between magnets filled with cold welding.
- We proceed to grinding the surface of the engine.
- We use the tester to find the working winding. We leave its wires, and delete all the rest. We pass the wires through the rectifier. We connect their ends to the controller. The controller is connected to the battery.
A homemade generator from a washing machine engine is ready to use. To unwind the device, an electric drill, screwdriver, or other similar tools are suitable. Such a generator, of course, will not be able to provide electricity to your residential area, but it is quite suitable for lighting a couple of rooms or operating several devices such as TV, refrigerator, computer.
Useful video
As you can see, the range of use of spare parts for an old washing machine is quite large. So what are you waiting for? Breathe a second life into served its term washing machine.
From parts from a washing machine, regardless of its condition and type, you can make a variety of useful devices and devices.
They can perform various mechanical work, as well as play the role of generators of free reserve energy. For the manufacture of homemade products with an electric motor, cases, wiring and other spare parts will fit.
Attachment options
The following describes what can be done from an old washing machine. These devices will be useful for housekeeping, construction, gardening and repair.
The most common homemade is emery. Since the diameters of the motor shaft and the grindstone are different, you will need to make a matching adapter. His role will be played by a piece of a 20-centimeter pipe. At the end of the latter, a carving should be made so that it is twice as long as the grindstone. Its direction must be opposite to the rotation of the motor. This is necessary so that the grinding wheel does not unscrew and fly off.
The adapter should be fixed on the motor shaft. Then you will need to drill a hole there, and screw in the bolt and nut to finally fix the emery wheel with the adapter. It remains to strengthen the homemade product on a solid foundation.
The motor power from the washing machine is enough for a small lathe or drum grinder. In the first case, you can slowly process a cylindrical workpiece. For more reliable fastening, a support should be used that will protect the motor from excessive lateral loads. In the second case, a cylinder is put on the motor shaft, on which sanding paper is put on. Inside it should also be installed a steel bar, with which you can fix it on the motor shaft.
An old activator-type washing machine can turn into a small concrete mixer. For this you should:
- To make blades, for which it is necessary to cut blanks from 4-5 mm steel, connect at a right angle (in the form of the letter P), and weld.
- Attach the part in place of the activator.
- Connect the motor to the mains (see below).
- It remains only to put the necessary building materials in the tank.
- The motor power in this case will be sufficient for small volumes.
You can also make a feed cutter. In addition to the engine, you will need a drum from the washing machine. It is necessary to make two sharpened blades that play the role of knives. The drum is attached to the support frame with bolts. An outlet hole should be made in its lower part. One blade with a knife is installed at the bottom, and the other is closer to the top. A cover must be attached to the opening in front of the drum so that the feed does not scatter around.
Another possible homemade product is a lawn mower. It will work no worse than the factory one. For its manufacture you will need:
First you need to weld a square frame with axes. In the base, which is attached from its lower side, a hole should be made for the motor shaft, and then fixed. From longer pipes, a U-shaped handle should be made. A rubber casing is put on its horizontal part to make it more convenient to hold. A wire with a switch is connected to the motor. If you plan to use wet grass for cutting, then you must carefully insulate all conductive parts.
Finally, last device what can be done from washing machine, - This generator. Asynchronous motor will require further development. It is necessary to disassemble it, cut grooves in the rotor, into which neodymium magnets must be inserted and glued by cold welding. The working winding will need to be connected to the controller, which stabilizes and rectifies the current induced in it and provides the specified voltage.
Such a generator will be able to power the lamp or charge the battery. The rotor can be driven by a drill, a screwdriver, or a pedal mechanism. Other options are also possible.
Types of motors
Older washing machines used asynchronous electric motors. They consist of a wound stator and a cylindrical rotor driven by a rotating magnetic field. They are characterized by low noise, simple design, and sufficiently high power. But there are also disadvantages - these are large dimensions and weight, the complexity of smooth speed control, and low efficiency and torque. They also cannot work as a generator without modification.
The most common are two-phase asynchronous motors
. They have a working and starting winding. The first is connected directly, and the second - through a phase-shifting capacitor. Currently, asynchronous motors are not used in washing machines.
The collector motor is used in all modern automatic washing machines. Works from direct and alternating current. It consists of a stator and a rotor, the magnetic fields of which interact, as a result of which the latter rotates. It is equipped with a collector through which voltage is applied to the winding through the brushes. Advantages - high torque and considerable speed, which can be easily and smoothly adjusted. Collector motors are also capable of operating in the generator mode with external excitation.
The inverter motor is connected directly to the drum. It has a rather complex structure. This motor can work as an efficient generator if the motor manufacturer has installed magnets in the rotor, due to which a considerable current will be induced in the stator.
Connection and verification
You need to make sure that the selected motor is working. To do this, determine the conclusions of the windings using a tester or multimeter. To check the operability of the collector motor, you need to connect one wire of the cable with a plug to one brush, and the other to the winding output. Free conductors are connected to each other. If the engine is working, the rotor will start to rotate.
An asynchronous motor is connected differently. First you need to determine the working and exciting windings. The first will have more resistance. Power is supplied to it directly, and to the exciting one - through a phase-shifting capacitor.
When the washing machine breaks down and it is no longer practical to repair it, it becomes necessary to purchase a new one. Do not rush to throw away the old washing machine. If, then why good disappear. From it you can make many useful things that will be useful to you around the house. Let's look at what can be done from the engine from an old washing machine.
Electric emery from the engine of a washing machine
One of the options for using the engine from the machine is the manufacture of electric emery. This device will be very useful in the household. Thanks to him, you can quickly sharpen a knife, drill, scissors and any other cutting tool. Of course, the task is not one of the easiest, but with a skillful approach, everything can be done quickly enough.
The first and most important task is to attach a grindstone to the engine itself, or rather, to the engine shaft. The problem is that the main diameter of the hole in the grindstone and the diameter of the washing machine motor shaft are completely different. This problem is being solved. It is necessary to prepare a special flange, which will have two different sides. On the one hand, there will be the necessary thread to securely fasten the emery wheel, and on the other hand, the motor shaft will be pressed in. To make the flange, you will need a small piece of steel pipe with a diameter of 32 millimeters.
Flange manufacturing process:
- We take the necessary pipe (by 32 millimeters). The length of the pipe should not exceed 20 centimeters.
- Now you need to cut the thread on one end of the pipe. For reliable fixation of the flange on the shaft, it is necessary that the thickness of the emery wheel be half the length of the thread. It is very important to consider the direction of the thread. It should be cut in the opposite direction of rotation of the motor shaft. Otherwise, the whetstone will simply fly off the shaft during rotation.
- The other end of the shaft must be heated with a blowtorch and pressed onto the shaft. After cooling, the pipe will securely fasten to the shaft. For a stronger connection, you can weld the pipe to the shaft. If there is no welding, then you can simply drill a hole and connect with a bolt and nut.
- Now you need to pick up three nuts and two washers of the required size. At the end of the threaded pipe, we screw one nut all the way, put on the appropriate washer, then an emery wheel, then another washer and tighten it all with the second nut. You need to tighten everything tightly, and at the end also secure it with a third nut.
The main task is completed, now you need to secure the engine in a secure way. The mounting stand is made depending on the availability of mounting holes on the . After making the stand, we fix the engine on the workbench. Engine brackets on some washing machines perfect for mounting on a workbench.
Electrical connection
After the engine with emery is fixed on the workbench, you need to connect it to the power supply.
This completes the manufacturing process of electric emery. The device is ready to work.

Feed cutting technology
The feed cutter is ready to go. Thanks to such a device, in just one hour, up to 100 kilograms of raw materials can be processed in various cities.
Making a concrete mixer from a washing machine engine
If you are planning a construction project, then do not rush to throw away your old washing machine. From it you can make a full-fledged concrete mixer, which will greatly facilitate your construction process.
The process of performing work on the manufacture of concrete mixers
Making a generator from a washing machine engine
From the engine of the machine, you can make a 12 V generator. To make it does not require a lot of work and a lot of additional materials. All that is needed is 32 specially sized magnets (20 x 10 x 5 millimeters). 
The whole process of alteration is that you need to remove the core layer and install special magnets. The rotor has four poles, each pole has eight magnets. On a lathe, you need to remove a small layer of the core and install magnets in these recesses. Then the poles must be filled with epoxy resin, after wrapping them with paper. Now you need to install new bearings. Find the working winding, and cut off the old wires. The generator is ready to work.
If you have imagination, working hands and the necessary knowledge, then on the basis of the above examples, you can assemble other devices and devices for various purposes. All the fundamental principles are set out in the examples above. The analogy of production in most cases will be the same, with the exception of characteristic nuances.
