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 the 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 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 motor shaft washing machine totally 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. 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 manufacturing process of electric emery. The device is ready to work.

Making a generator from a washing machine engine

From the engine of the machine, you can make a 12 V generator. To make it is not required great job and many 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.

A grinding machine made from a washing machine engine: detailed drawings and step-by-step photos of making a homemade machine.

When a washing machine breaks down beyond repair, the engine is usually left in full working order and can be used to make crafts, such as a homemade grinder. We will consider the manufacture of such a machine in this article.

Then you need to turn at the turner just such a part on the motor shaft. The figure shows the drawings.

Turned detail.

You will also need these details.

From sheet metal let's make a bed.

Vertical stand.

From the details we assemble the lever.

This screw adjusts the angle of the tape, for convenience, a bottle cap is put on the screw.

The base of the machine is made from a 40 mm corner.

To attach the lever to the frame, support bearings and a 12 mm bolt are used.

Let's make a base plate from a corner and a plate. You will also need a roller from the timing of the car, glue a piece of the timing belt on top so that the tape does not slip.

Additionally, you can make a few more rollers smaller, since the smaller the roller size, the lower the speed of the tape. At a slower speed, softer materials are processed; for hard materials, a large roller should be used.

Our homemade grinding machine is ready. The emery tape on it is used from a grinder, which is cut into several tapes. There are several holes drilled into the upright to accommodate different lengths of emery bands.

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 products from the engine from the washing machine.

What can be collected?

Homemade products from a washing machine engine are used in the 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 interesting ideas homemade 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 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. Fastened to the platform in front protective mesh. 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.

Old washing machine great material for the design of a large number of useful household appliances. From different parts of the unit, you can make a brazier, a smokehouse, a preservation sterilizer, a grinding wheel, and even a concrete mixer. Quite often, owners of Soviet-style washers assemble 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 method of attaching the emery wheel to the shaft, and prepared all the auxiliary parts, tools and fasteners.

In terms of power and configuration, an electric motor from old-style washing machines is ideal for portable homemade emery. As a rule, for this purpose, motors from units such as Siberia, Volga or Vyatka are used. 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 an emery from a more powerful type of engine, a significant number of revolutions can simply break the grindstone in the process.

The parameters of the engine 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 quite cope with household sharpening of repair equipment and kitchen utensils.

old engine

A faster grinder (for example, emery based on common engines with 2.8 thousand rpm) is appropriate to use for grinding or polishing parts. In this case, the emery stone should be stronger, and the main fastener, the flange, should be better and stronger.

Advice. To assemble emery from the engine with your own hands, you can use both a 1-phase and a 3-phase motor.

What materials and tools are needed for homemade emery

Take care of all the accessories in advance. You will need electrical equipment:

• capacitor and switch (can be removed from the same washing machine);
• wiring;
• plug with cable.

Materials for processing the engine for emery:

• flange;
• a small piece of galvanized sheet;
• grinding wheel (you can even have a set of stones with different grain sizes to change depending on your needs).

Elements for assembling the emery support frame:

• a pipe with a wide rectangular section;
• two pipe segments with a smaller section of the same shape;
• a couple of corners;
• rubber pads.

Accessories for the emery table:

• square pipe;
• metal plates - 2 pcs.;
• nuts and bolts.

Tools:

• 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 primer paint.

First of all, take care of fixing the stone on the motor shaft. For these purposes, a flange is used, but without a lathe, it is quite difficult to fasten both parts. It is better to resort to the services of a specialist. His tasks:

• prepare a flange for reliable connection with the shaft;
• secure the contact with a washer;
• make a thread on the flange that would fit the sleeve nut and not contradict the direction of rotation of the engine.

If the shaft rotates counter-clockwise, you will need a right-hand thread, and vice versa. Otherwise, the nut will unwind during operation. This is against safety precautions, as the whetstone may fly off. Make a sleeve from a pipe, for example, with a section of 32 mm. Put a circle of emery on it. The gap between the motor shaft and the pipe should be compensated by uniform twisting of electrical tape.

Assembling emery from a washing machine engine

The process of assembling the basis of the future grinding device takes place in a vice. After almost every action, fitting and fitting is required so that the device will work without failures in the future. During the layout of the emery, you can focus on auxiliary photo and video instructions.

1. Make a drawing based on the basic parameter - the dimensions of the engine. Consider the dimensions of the support and bed.
2. Make a pattern of elements of supporting and fastening structures.
3. Transfer the contours to the metal corner. Cut out the details with a grinder.
4. Make a support frame for the emery. Fix the blanks of the rectangular section pipe on the workbench with a clamp. Saw where necessary, 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 pipes of a smaller area.
5. Cut a window in the larger pipe, which will be a technological hole for the capacitors. They need two. Connect the terminals of the parts together with parallel wiring.
6. Insert the capacitors into the recess. If everything connects perfectly, disassemble the structure and carefully sand all metal surfaces.
7. All structural elements of the emery are welded to each other.
8. Make a table on which the part will be located during the turning process. Metal, 3 mm thick, will be strong enough for these purposes.
9. Paint the bed. Fasten the engine housing with the wheel to the machine, covering it from sparks and scales from getting inside. To do this, cut a round casing from galvanized sheet.

The work is completed by assembling the circuit and connecting it with capacitors. This is the easiest way to self-assemble emery from the washing machine motor. The tool is reliable. Provided correct operation it will last you more than one year.

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

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: they work with both variables 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 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 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:

1. We take out the activator from the car.
2. Cut out from sheets steel 4-5 mm thick blanks for the manufacture of blades.
3. We weld a pair of U-shaped blades, connected at right angles.
4. 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:

1. At the bottom of the body create a hole through which the finished feed will exit.
2. 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.
3. 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.
4. 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 homemade 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;
• hammer;
• drill, screwdriver, pliers;
• soldering iron.

Let's get to work:

1. At the center of the base cut holes for the motor shaft. Install it upside down.
2. We attach earlier bushing on the shaft, and we attach a disk (knife) to it.
3. From the corners we assemble the frame for the motor.
4. We weld the handle, fix the switch to it
5. 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:

1. Dismantling the motor housing. Using a lathe, we make a cut on its core with a depth of 2 mm.
2. In pre-prepared grooves on the core insert neodymium magnets.
3. 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 fit snugly 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:

1. We glue the template on the motor. We glue magnets on the template itself.
2. Please note that the distance and angle between the magnets do not change. Otherwise, voltage drops, power reduction or its complete inoperability are possible.
3. Free space between magnets filled with cold welding.
4. We proceed to grinding the surface of the engine.
5. 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.
