From parts from washing machine, regardless of its condition and type, you can make a variety of useful devices and adaptations.

They can perform various mechanical work and also 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 in order 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 them 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 to prevent feed scattering 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 revision. 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

In older washing machines applied asynchronous 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 asynchronous 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 washing machines... Powered by constant 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 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.

When a washing machine breaks down and it is no longer expedient to repair it, then it becomes necessary to purchase a new one. Don't rush to throw away your old washing machine. If, then why should the good be lost. You can make many useful things from it that will be useful to you around the house. Let's look at what can be done from an engine from an old washing machine.

Electric emery from a washing machine engine

One of the options for using an engine from a typewriter is the manufacture of electric emery... This device will be very useful in household... Thanks to him, you can quickly sharpen a knife, drill, scissors and any other cutting tool. Of course, the task is not an easy one, but with a skillful approach, everything can be done quickly enough.

The first and foremost task- this is to attach a whetstone 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 motor shaft washing machine totally different. This problem is being addressed. You need to prepare a special flange that 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 need a small piece of steel pipe with a diameter of 32 millimeters.


Flange making process:

  • We take the necessary pipe (32 mm). The pipe length should not exceed 20 centimeters.
  • Now you need to thread one end of the pipe. To securely fix the flange on the shaft, it is necessary that the thickness of the emery wheel is 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 as it rotates.
  • The other end of the shaft must be heated with a blowtorch and pressed onto the shaft. After cooling down, the pipe will be securely fastened 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 the emery wheel, then another washer and tighten it all with the second nut. You need to tighten everything tightly, and at the end also fix it with a third nut.

The main task is completed, now you need to secure the engine in a reliable way. The mounting stand is made depending on the presence of holes for mounting itself. After making the stand, we fix the engine on the workbench. The motor brackets on some washing machines are great 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 process of making electric emery. The device is now ready for use.

Feed cutter manufacturing technology


The feeder is ready for use. Thanks to such a device, in just one hour, you can process up to 100 kilograms of raw materials in various cities.

Making a concrete mixer from a washing machine engine

If you are planning a construction site, then do not rush to throw away your old washing machine. You can make a full-fledged concrete mixer from it, which will greatly facilitate the construction process for you.

The process of performing work on the manufacture of a concrete mixer

We make a generator from a washing machine engine

A 12 V generator can be made from a car engine. To do it, you do not need a lot of work and a lot of additional materials. All that is needed are 32 custom-sized magnets (20 x 10 x 5 millimeters).

The whole alteration process consists in removing the core layer and installing special magnets. The rotor has four poles, with eight magnets per pole. On a lathe, you need to remove a small layer of the core and install magnets in these grooves. Then the poles must be filled with epoxy resin, having previously wrapped them with paper. Now you need to install new bearings. Find the working winding, and cut off the old wires. The generator is now ready for operation.

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 of the fundamental principles are outlined in the examples above. The analogy of production in most cases will be the same, with the exception of the characteristic nuances.


A neighbor at the entrance put an automatic washing machine on the landing for further removal to the trash, as a repairman told him, a kirdyk came to the motor. Not only Samodelkin, not when in life, will pass by the thrown out unit without taking it for parts or at least not looking inside at the contents. I am sick of the same, I decided to save my neighbor from hard physical work, taking the unit to the trash can and took it for spare parts to my village.

In the photo: One of the most useful parts of the inside of a washing machine.

Everything was dismantled into useful bells and whistles and it was time to check the condition of the engine.

Paragraph 1. Checking the motor.

To check the motor and upgrade the Lighting Dimmer, we need tools.
* Instrument (tester)
* Electrician's side cutters
*Dimmer
* Soldering iron

Inside there was such a collector universal motor MCA 52 \ 64 -148 \ KT11 390W. 13000 RPM






In the picture we see a seven-pin large connector, on the left all monochrome blue wires come out (to make it more difficult for the layman to understand) and one yellow-green (ground), on the right there are wires that go directly into the motor, if you look from the top, then two red (on the travel sensor ), blue for brush 1, purple for another brush 2, black (midpoint of the motor windings), orange (two stator windings).


We will strip all the outgoing blue wires for continuity with their device.


Disconnect the connector and call the tester which of the blue wires to which motor wire comes, so as not to forget, you need to write down, sketch.




For a simple start of the motor, we only need two orange, blue and purple wires, the rest can be bitten off or isolated for future homemade products.

According to this scheme, you need to connect the motor.


You can check the operation of the motor, everything works (as in most cases it does), only the bearings should be replaced.

This is how the repair specialists carry out the diagnostics, the price of such a new motor is 6000 rubles + installation work.

Point 2. Reverse.

This type of motor can be reversed, which is what the washing machine does during washing, for this you need to change the connection of the brush from one winding to another, only to do this after a complete stop and the motor is de-energized.

Scheme. Reverse with a toggle switch.

The toggle switch itself.

Point 3. Regulation of revolutions by a light dimmer.

You can also adjust the speed by decreasing - increasing the current, for example, using a wire rheostat of the required power or using a triac with a PWM controller.

As the simplest and most affordable, this is a dimmer for lighting (photo below), only before the first connection it is necessary to look at what maximum current the regulator is designed for, we need a tenfold overlap of the rated motor power, because starting current our motor jumps from 8-10A and above, even without load.

The cheapest dimmer.


If the dimmer turned out to be like mine at 3A, then it can be modified by finding the necessary triac directly on the control board of the washing machine itself, where all the parameters are just calculated for this motor.




To do this, we will trace the path from the place where the motor terminal is connected to the board and along the widest paths, one of which will definitely fit on one of the legs of the part we need (in my case, this is a BTB16 triac with three legs).


Disconnect the radiator mount and solder the part being careful not to overheat.


We solder the resulting triac together with the radiator to replace the old part in the regulator, now you can safely connect a load of 10 A and at the time of start-up even up to 16A.

No matter how good the thing in the house is, it eventually falls into disrepair. People throw them away so that these things do not gather dust at home and do not take up space. From old furniture or various electrical appliances, you can make many different crafts that will always come in handy on the farm. This can be attributed to the washing machine as well. And if the washing machine is old, then do not rush to send it to the landfill. It is better to disassemble this car in detail. Any detail will fit for creating a homemade product. And if the electric motor is in order, then a pretty decent sharpener will come out of it for sharpening the tool.

Removing electrical equipment from the washing machine

So, for the manufacture of a sharpening machine we use electric motor AD-180-4 / 71S1U4 from the washing machine. Its power is 180 watts. We remove this engine very carefully. We remember how the electrical wiring is connected. After all, the motors used in them are single-phase. They have a working and starting winding and are started through a capacitor. So, the recommendation to remember the connection of the wires is not at all superfluous, it would be even better to mark them so that you know how to connect later. Otherwise, it will be a pity for the stupidly burned electric motor.

Dismantling the engine and adding grease to the bearings

We also disassemble the engine. When disassembling, it is advisable to use pullers. After the rotor has been removed, it is advisable to remove and check the condition of the bearings. If they are unsuitable, then we simply replace them with new ones. And if their condition is normal, then we rinse them, and put fresh lubricant there. Lubricants work well Tsiatim 221, Tsiatim 201 and Litol 24.

Shaft shank rework

Before assembly, it is necessary to cut the M12 thread on the shaft shank with a pitch of 1.25. It is advisable to do this on a lathe in order to avoid unwanted beating of working tools. This is necessary for screwing and fixing on the shank of a standard chuck used for a drill. And he just has such landing parameters. The chuck clamp is designed for a diameter of 12 mm. Having such a chuck, we provide an easy replacement of tools used during work.

Assembling the motor

The assembly is carried out in the reverse order to how it was disassembled. We assemble the motor itself carefully so as not to damage the windings and housing covers.

Install on the engine special connector block for a secure connection of wires.

Working on a sharpener, we get dust and dirt. To prevent it from getting into the engine, it is necessary to install a protective washer on the engine from the side of the working tool. We leave a small gap between the motor and the washer. It is necessary for the free passage of air, which cools the motor windings.

Installing the engine on the bed

Now, the electric motor needs to be secured to the bed. To do this, take corners measuring 50 by 50 mm. We fix them to the bed with M6 bolted connections. And to the corners we attach the engine to the native M10 bolts. The axis of the shaft from the bed is at a height of 140 mm. This allows you to use a variety of tools for processing and sharpening products. Such as sharpening stones, discs.

All homemade covered with a casing... It is made of sheet metal. It is going on rivets. For access to homemade parts, the rear wall of the casing is removable. For good ventilation, which is needed to cool the homemade motor, holes are drilled in the back wall. The homemade casing is attached to the bed with self-tapping screws. Mount the switch on the side of the casing.

To expand the possibilities of the sharpener, we independently manufacture some tool attachments or buy from the retail network.

So, the very mechanics sharpened, ready.

Connecting an electric motor to a 220 V network

Now it is necessary to carry out the correct connection of the motor from the washing machine. It's very good if wires are marked... Then there should be no problem. Everything is connected as it was connected before disassembly. We fix the capacitor on the frame with clamps and fix them with M5 bolts. It would be nice to bring the conclusions from the engine directly to the block. But if the marking of the wires was not done and while they were engaged in mechanics, they forgot all the connections, then you have to work a little and remember electromechanics.

So, we know the engine. This is AD-180-4 / 71S1U4, 180 watts. He has four conclusions. It is a single phase motor that has two windings. One is working and the other is launcher. In order to find out where we have a working and starting winding, we take a tester. We install it on an ohmmeter and measure the resistance of these two windings. In which the winding resistance is greater, then the starting one, and less - then the working one.

Let's designate the conclusions of the windings of our electric motor. The beginning of the working winding is denoted by C1, and the end by C2. The beginning of the starting motor winding is P1, and the end is P2. Now, you need to check insulation quality winding wires. A 500V megohmmeter is required to do this job. We measure the insulation resistance, it should be 0.5 mΩ or more.

We draw up a circuit where the working winding, through a toggle switch, is connected directly to the network. The starting winding is connected through a capacitor (not an electrolyte). Since our sharpener has a small starting torque, then additional installation a capacitor is not required at the time of start-up. Having completed the marking of the terminals, we proceed to the assembly of the engine starting circuit. We also mark the terminals on the block. The upper row of terminals is designated from left to right, 1,2,3,4. We mark the bottom row from right to left, 5,6,7,8. We connect the leads from the windings to the terminals of the block as follows:

  • The leads from the working winding C1 and C2 are connected respectively to the terminals marked 1 and 2.
  • Conclusions from the starting winding P1 and P2, respectively, to terminals 3 and 4.
  • We connect with a wire from terminal 8 of the block to one of the toggle switch terminals.

Now we take a two-core network wire. On one side of the cable, we connect one end to terminal 7, and the other to the toggle switch terminal. On the other hand, the cable ends are connected with an electrical plug.

Now, it is necessary to connect a capacitor installed on the frame in series to the starting winding of the motor. To do this, we connect the soldered wires from the capacitor to the terminals pads 4 and 5... To complete the connection process, do the following.

Connect with jumpers among themselves the following terminal blocks:

The connection is complete.

The sharpener is ready for use.

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 the 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 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 ones interesting ideas homemade 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 semiautomatic - it doesn't matter) 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 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). For safety precautions, the plug and socket are placed on the handle.

Feed chopper

The popularity of homemade products from over time only grows. Recently, feed cutters are increasingly being made. This will also require a drum.

4 bolt holes 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 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 lid 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.
