After just a few years, I want to replace them with newer and more sophisticated ones. But it is a pity to throw away the old equipment that is still working. Therefore, it can be given a "second life". Very often, a washing machine acts as a basis for homemade products. Absolutely all elements can be used from it: engine, wiring, housing, drum, legs. But the most common homemade products from the engine from the washing machine.
What can you collect?
Homemade products from the washing machine engine are used in households. They can greatly facilitate many types of work. In particular, the following devices are collected:
- Electric emery, which is essential for sharpening knives, drills, tools and so on.
- A lawn mower that allows you to mow grass in your summer cottage.
- A feed chopper that cuts greens into small pieces.
- Concrete mixer.
- Cleaver for firewood.
- Potter's wheel.
- Lathe.
- Generator.
This is not a complete list of what can be assembled from a washing machine engine. In fact, there can be a lot of ideas. Fans of tinkering with electronics come up with all new interesting ideas for homemade products from the engine from the washing machine. Therefore, we will dwell in detail on just a few examples.
Emery
One of the most popular homemade products from a washing machine engine (automatic or semi-automatic - not the point) is an electric foot.
The first step is to prepare the flange. Its need is due to the fact that the shaft from the motor has one diameter, and the grindstone hole has another. One side of the flange will be pressed onto the motor shaft. The second side needs a thread 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 the carving. Its length should be approximately 2 times greater than the thickness of the circle. It is also important to choose the right direction. The thread should be directed in the opposite direction from the direction of movement of the shaft. If the shaft rotates to the right, 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 other end of the flange (which is unthreaded) is pressed onto the motor shaft. To do this, it must be heated with a blowtorch. To obtain a stronger connection, the joint is bolted or welded.
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 mount must be very reliable and durable so that the structure does not move during operation. After that, the motor is connected to the network.
Lawn mower
Lawn mowers are popular homemade products from a washing machine engine.
As a basis, you can take a frame from a stroller or trolley. If there are none, you can make a frame from metal corners. A metal sheet is attached to the finished frame, which will act as a platform. A protective mesh is attached to the front of the platform. Handles are made of pipes. A rubber casing is put on top of it.
The engine is mounted on a platform. In the center of it, a hole for the shaft is being prepared, to which the knife will be attached. The motor is connected to a cable with a plug (or switch). For safety reasons, the plug and socket are placed on the handle.
Feed chopper
The popularity of homemade products only grows over time. Recently, feed cutters are increasingly being made. This will also require a drum.
4 bolt holes are made in the drum walls. 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 hand, for unloading the finished feed. Two knives are used. One is installed at the bottom of the drum. He has to toss feed. 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 the food from scattering to the sides, a cover is made. It is necessary to make a hole in it through which the raw material will be fed.
As you can see, homemade products from a washing machine engine are widely used in the household.
A variety of useful devices and fixtures can be made from parts from a washing machine, regardless of its condition and type.
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, housings, wiring and other spare parts will fit.
Fixture options
Here's what you can do with an old washing machine. These devices will be useful for household, construction, gardening and renovation.
The most common homemade product is emery.... Since the diameters of the motor shaft and the grinding stone are different, a matching adapter will need to be made. Its role will be played by a piece of a 20-centimeter pipe. At the end of the latter, a thread should be made so that it is twice as long as a whetstone. Its direction should be opposite to the rotation of the motor. This is necessary so that the grinding wheel does not unscrew and fall off.
The adapter must be fastened to 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 reliable basis.
The motor power from the washing machine is enough for a small lathe or drum grinder... In the first case, you can slowly machine the cylindrical workpiece. For more reliable fastening, a support should be used that protects the motor from excessive lateral loads. In the second case, a cylinder is put on the engine shaft, on which sanding paper is put on. A steel bar should also be installed inside it, with which you can fasten it to the motor shaft.
An old activator-type washing machine can turn into a small concrete mixer. To do this, you should:
- Make the blades, for which it is necessary to cut out blanks from 4-5 mm steel, connect at right angles (in the form of the letter P), and weld.
- Attach the part to the place of the activator.
- Connect the motor to the mains (see below).
- All that remains is to put the necessary building materials into the tank.
- In this case, the motor power will be sufficient for small volumes.
You can also make a feed cutter. In addition to the engine, you will need a drum from a washing machine. It is necessary to make two sharpened blades that play the role of knives. The drum is bolted to the base frame. 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 lid must be fitted to the opening in the front of the drum so that the feed does not scatter to the sides.
Another possible DIY is a lawn mower. It will work just as well as the factory one. To make it you will need:
First you need to weld a square frame with axles. In the base, which is attached from its bottom side, a hole should be made for the motor shaft, and then secured. A U-shaped handle should be made from longer pipes. A rubber casing is put on its horizontal part to make it easier to hold. A wire with a switch is connected to the motor. If it is planned to use it for cutting wet grass, then all conductive parts must be carefully insulated.
Finally, the last device that can be made from a washing machine is generator... The asynchronous motor will require improvement. It is necessary to disassemble it, cut grooves in the rotor into which neodymium magnets must be inserted and glued with cold welding. The working winding will need to be connected to a controller, which stabilizes and rectifies the current induced in it and provides a given voltage.
Such a generator will be able to power the lamp or charge the battery. The rotor can be driven by a drill, screwdriver, or pedal mechanism. Other options are also possible.
Types of motors
Older washing machines used induction motors. They consist of a wound stator and a cylindrical rotor that is driven by a rotating magnetic field. They are distinguished 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 function as a generator without rework.
The most common are two-phase induction motors... They have a working and starting winding. The first is connected directly, and the second is connected 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. Powered by AC and DC. 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 supplied to the winding through the brushes. Advantages - high torque and considerable rotation speed, which can be easily and smoothly adjusted. Brush motors are also capable of operating as an externally excited generator.
The inverter motor is directly connected to the drum. It has a rather complex design. This motor can work as an efficient generator if the manufacturer of the electric motor has installed magnets in the rotor, due to which a considerable current will be induced in the stator.
Connection and verification
Make sure the selected motor is running. To do this, determine the conclusions of the windings using a tester or multimeter. To check the operation 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 terminal. Free conductors are interconnected. If the engine is working properly, the rotor will start to rotate.
The asynchronous motor is connected in a different way. 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.
An old washing machine is an excellent material for constructing a large number of useful household appliances. From different parts of the unit, you can make a brazier, a smokehouse, a sterilizer for conservation, a grinding wheel and even a concrete mixer. Quite often, the owners of Soviet-style washers collect a grinding device or emery from an engine. It is not difficult if the motor is in good working order, you have thought out the way of attaching the emery wheel to the shaft, all auxiliary parts, tools and fasteners are prepared.
In terms of power and configuration, the electric motor from old-style washing machines is ideal for portable homemade emery. As a rule, motors from units such as Siberia, Volga or Vyatka are used for this purpose. Approximate characteristics should be as follows:
- mains voltage - 220 V;
- power - up to 370 W;
- rotation speed - no more than 3 thousand rpm.
Attention! If you construct emery from a more powerful engine, a significant number of revolutions can simply break the grindstone during operation.
The engine parameters are necessarily indicated on its body. For the manufacture of emery, a device with a power of 100-150 W and 1-1.5 thousand rpm is sufficient. He will perfectly cope with household sharpening of repair tools and kitchen utensils.
Old engine A faster grinder (for example, emery based on common engines with 2.8 thousand rpm) is appropriate for grinding or polishing parts. In this case, the emery stone should be stronger, and the main fastening element, the flange, should be of better quality and stronger.
Advice. To assemble emery from the engine with your own hands, it is allowed to use both 1-phase and 3-phase motors.
What materials and tools are needed for homemade emery
Take care of all the components in advance. You will need electrical equipment:
- capacitor and switch (can be removed from the same washing machine);
- wiring;
- plug with cable.
Materials for recycling the emery engine:
- flange;
- a small piece of galvanized sheet;
- grinding wheel (you can even a set of stones with different grain sizes to change depending on your needs).
Elements for assembling the emery support frame:
- pipe with a wide rectangular section;
- two pipe sections with a smaller section of the same shape;
- a pair of corners;
- rubber gaskets.
Emery table accessories:
- square tube;
- metal plates - 2 pcs.;
- nuts and bolts.
Instruments:
- welding machine;
- drill;
- hand files;
- Bulgarian;
- vise and clamp;
- locksmith and measuring devices;
- electrical tape with a fabric base;
- angle grinder.
Advice. At the end of the work, it is better to cover the metal parts of the emery with a primer paint.
First of all, take care of fixing the stone to the motor shaft. For these purposes, a flange is used, but without a lathe, it is rather difficult to fasten both parts together. It is better to resort to the services of a specialist. Its tasks:
- prepare a flange for a reliable connection to the shaft;
- fix the contact with a washer;
- make a thread on the flange that would be suitable for the nut-sleeve and does not contradict the direction of rotation of the engine.
If the shaft rotates counterclockwise, you need a right hand thread and vice versa. Otherwise, the nut will loosen during operation. This is against safety precautions, as the whetstone can fly off. Make the sleeve from a pipe, for example, with a cross section of 32 mm. Place a circle of emery on it. The gap between the motor shaft and the pipe should be compensated for with a uniform twist of electrical tape.
Assembling emery from a washing machine engine
The process of assembling the base of the future grinding device takes place in a vice. After almost every action, fitting and adjustment is required, so that in the future the device will work without failures. During the layout of the emery, you can focus on the auxiliary photo and video instructions.
- Make a drawing based on the basic parameter - the dimensions of the engine. Consider the dimensions of the support and bed.
- Make a pattern for the elements of the supporting and fastening structures.
- Transfer the outlines to a metal corner. Saw out the parts with a grinder.
- Make an emery support frame. Fix the blanks of the rectangular cross-section pipe on the workbench with a clamp. Saw where needed with a grinder. In a pipe with a larger cross-sectional area, grooves must be cut at the edges in order to connect to the side of the pipes of a smaller area.
- In the larger pipe, cut a window that will be the technological opening for the condensers. You need two of them. Connect the terminals of the parts with parallel wiring.
- Insert capacitors into the recess. If everything connects perfectly, disassemble the structure and carefully sand all metal surfaces.
- Weld all emery construction elements to each other.
- Make a table on which the part will be located during the turning process. Metal, 3 mm thick, will be strong enough for this purpose.
- Paint the bed. Secure the motor housing with the circle to the machine, shielding it from sparks and scale. To do this, cut out a round galvanized sheet cover.
The work ends with the assembly of the electrical circuit and its commutation with capacitors. This is the easiest way to self-assemble emery from a washing machine motor. The tool turns out to be reliable. Provided it is used correctly, it will serve you for more than one year.
How to make a sharpener: video
A situation often arises when it is necessary to sharpen a tool or sharpen knives. To perform these works, a sharpening machine is best suited - it is also called a sharpener or emery. This is the simplest power tool, which consists of electric motor and abrasive wheel... Many options are sold in the trade network, which differ from each other in price and manufacturer, but are designed to perform one function - sharpening the cutting tool. Do not rush to purchase a factory-made electric sharpener: any home craftsman can make it with his own hands if he has the necessary spare parts.
To make emery yourself, you first need to choose a suitable electric motor. Most often this is a motor from an old-style washing machine, for example, Malyutka - it is perfectly suited for this purpose. Such a motor meets certain requirements: its power is within 100-200 W, and the number of revolutions does not exceed 1500 rpm. If the speed is higher, then there is a danger of breaking the abrasive wheel.
High engine speeds are needed to polish parts, but they are not suitable for sharpening.
To make a homemade emery, you can use any another electric motor. It must meet certain parameters.
- Shaft rotation should be minimal. Motors with no more than 1,000 revolutions per minute are best suited.
- The motor power must be between 100 W and 1 kW. The most commonly used motors are 400 watts.
- It is desirable that he has paws for fastening.
- A single-phase or asynchronous motor is best suited, designed to be connected to a 220 volt network.
Algorithm for assembling emery from the engine from the Malyutka washing machine
First of all we do the frame of the future mechanism... It can be made from thick wood board, wood board, suitable plastic, but thick metal board works best. An electric motor is fixed to it using brackets, corners or clamps. The connection of the electric motor to the stone takes place by means of a flange.
Homemade Flanders
Flange making- one of the technically difficult operations in the assembly of homemade emery. It is usually done using a lathe. To do this, it is necessary to measure the diameter of the output shaft and the abrasive wheel, which will be used in the grinding machine. However, if a lathe is not at hand, you can do without it. In the video below, you can find out how to make an emery flange from improvised material yourself:
Flange fastening on the shaft by means of a nut with a bolt and a washer. In this case, the direction of rotation of the shaft must be taken into account: the thread on the nut must be in the opposite direction.
This is done for safety reasons so that during operation the nut does not unwind under the influence of the vibration of the machine, which is fraught with flying off the abrasive wheel and injury.
Finally, it remains to mount the electric grinder to a permanent place and supply electricity. Emery from the engine from the Baby is ready.
In the case of using an engine dismantled from an automatic washing machine, you can make a sharpening machine in the same way, the only difference is in connecting the electricity. The motor from an ordinary washing machine has four wires: two are connected to the working winding, and the other two are connected to the starting winding. To determine the working winding, it is enough to measure the resistance of both. The resistance of the starting winding is 30 ohms, and the working one has only 12 ohms. The motors of modern machines have six leads, two of which are the output of a tachometer with a resistance of 70 Ohm. Finding them will not be difficult. These wires must be insulated.
Connection diagram is as follows: both windings are connected in parallel and connected to the network, and a button is connected to the break of the starting winding. To do this, you can take the launcher or adapt the button from the doorbell.
How to adapt a drill and grinder for an electric grinder
You can make emery not only from a suitable electric motor that is available. To do this, you can adapt a power tool - it can be an electric drill or a screwdriver.
The latter is less suitable for these purposes: it has insufficient power and a short battery life.
Making a sharpener from a drill begins with purchasing a nozzle.
A sharpening stone is fixed in it, and then clamped into a cartridge. It remains to fix it on a fixed base using a special mount, which can be bought at a store that sells power tools. With the help of such an electric grinder, you can fix an ax, sharpen a kitchen knife or refill a drill.
In case of emergency, the sharpener can be made from the grinder... This does not require the purchase of special devices and mandrels necessary for attaching emery. You just need to fix it in a horizontal position on a solid base, install a standard cutting or sharpening disc, and the sharpener is ready to work.
Mini sharpening machine
An electric sharpener is necessary if the master is modeling: Small parts often need to be sharpened when working. A large sharpener is not suitable for doing small work, so they often make mini-emery with their own hands. The assembly algorithm is as follows:
- take a motor from a computer hard drive or a child's toy;
- the spokes tension sleeve from the moped is soldered to the engine axis;
- a small grinding wheel is screwed to the shaft with a screw and washer;
- connect the power supply;
- fix the device to the bed, and the emery is ready.
Electric motors from a faulty sewing machine are often used for these purposes. The advantage of this machine is that the motor has a speed regulator, and this expands the capabilities of the device. It can be successfully applied and like a polishing machine.
Safety when working with a homemade device
When making power tools yourself, you should strictly follow safety precautions. If industrial units are equipped with protective equipment, then in self-made devices you will have to make them yourself. You should be aware that the operation of the sharpener from the engine of the washing machine without protective cover prohibited. It can be made from sheet metal with a thickness of 2.5 mm.
The working wheel experiences strong vibration during sharpening. To prevent the destruction of emery during operation, when installing a stone, cardboard gaskets are placed under the metal washers. You should also make sure that the disc is not cracked.
During work, you should stand to the side of the circle so that if it breaks, fragments do not fly into the operator.
In some situations, it is cheaper to purchase a new product than to restore broken home appliances. However, the prudent person will receive additional benefits by using functional components as intended. This publication presents homemade products from an engine from a washing machine .. And video clips will help you more accurately reproduce homemade craftsmen and get useful products quickly and at no extra cost.

What is the engine from an old washing machine suitable for?
First, you need to clarify the real capabilities of the existing power unit. In household appliances of the Soviet period, fairly reliable asynchronous electric motors (180-220 W) were installed. They were connected to two-phase AC networks. Previously, structures were created in a collapsible design. Therefore, in the event of a breakdown, the repair does not cause excessive difficulties. The only exception is damage to the windings. Modern models are distinguished by increased power (up to 340 W).
Since the late 90s of the last century, such simple engines have not been used. Instead of asynchronous, collector units are more often used. They are more compact, weigh less. The corresponding modifications provide the following possibilities:
- DC power connections;
- smooth speed control.
To supply current to the rotor part, graphite rods with spring pushers are used. These parts must be replaced periodically. The power of electric motors of the collector type is from 340 to 780 W at a rotational speed of the working shaft in the range of 11400-15200 rpm.
The photo shows the power unit, which was first used by engineers of the famous South Korean brand LG. It is often called inverter, since it is assumed that it is possible to smoothly adjust the speed of revolutions (up to 2 thousand per minute) using an external control device. The power of such units exceeds 500 W, which allows it to be connected directly to the drum shaft without a special belt drive. The following parameters and features of the motor from the washing machine determine where this power unit can be used:
- power;
- working shaft rotation speed;
- sizes;
- power supply and control circuit.
For your information! More attentive people pay attention to maintainability, reliability, resistance to external influences. They study the opinion of experts in specialized forums, the official guarantees of manufacturers.
What can be done from an old washing machine: examples of work with comments
The information below will help you implement different projects based on the appropriate powertrain. Here are the current homemade products from the motor from the washing machine, which proved to be good in practical tests. Some projects come with step-by-step instructions with detailed explanations of the build process.
How to make a grinder or sharpener from a washing machine engine
| Illustration | Description of action |
 | First of all, we will determine which replaceable nozzles will be used in practice. The features of the processing processes are of great importance: the duration of the cycles, the hardness of the material of the workpieces, etc. |
 | In this version, the author uses 200 mm diameter sanding discs with an adhesive layer on the non-working side. He picked up an approximate size of the nozzle from the "grinder" (175 mm) with a threaded connection in the central part. |
 | To implement the plans, an old washing machine engine was found, which rotates the armature at a speed of up to 1500 rpm. In the photo, the arrow marks the starting relay fixed to the case. Power supply - from an alternating current 220 V. |
 | A special nozzle has been created on the lathe. It is attached to a 14mm shaft with a screw. A threaded rod is welded to the end face of the part, which corresponds to the connecting unit of the adapter. |
 | During practical tests, it became clear that the initial rotation did not correspond to the direction of the thread. This means that when performing working operations, the nozzle will be unscrewed. The author did not use a special electrical circuit, but changed the places of the housing covers together with the bearing. |
 | For reliable fastening of the power unit, a special frame is created from steel corners. Welded joints are cleaned. At the final stage, the product is sequentially coated with a metal primer and paint. |
 | Using screws, a table (1) equipped with a rotating frame is connected to the bed. A support rod (2) with height adjustment is installed in the center. With its help, the exact angle required for working with workpieces is set. |
 | The assembly has confirmed the accuracy of the calculation and individual parts. To exclude errors, it is necessary to prepare a set of drawings in advance. Compliance with engineering standards is optional. However, it is necessary to carefully understand the features of each component of the structure, note the dimensions and landing dimensions. |
 | A practical test shows the good functionality of the new machine. Power is enough for processing duralumin blanks. An additional plus is the quiet operation of the washing machine engine. |
 | To collect and remove waste, a special box was made with a branch pipe for connecting a vacuum cleaner. It is installed at the bottom of the bed under the working area. |
For your information! Using this algorithm, it is easy to create a high-quality grinding machine from a washing machine. To increase safety, personal protective equipment should be used during processing. Also useful is a transparent polymer shield that covers the work area.
