A morally outdated or outdated household washing machine contains a lot of structural elements that, having been in the hands of craftsmen, can be useful in the household. Such assemblies include various switches and relays, pulleys, stainless steel drum, etc. However, most often there are homemade products using a washing machine engine.

Types of engines from washing machines

Washing machines are equipped with different types of motors depending on the design option. Among them are asynchronous, collector and inverter motors.

Asynchronous motors

Structurally, asynchronous electric motors consist of two main parts - a stationary stator and a rotor, the rotation speed of which can exceed 2500 rpm. Such a motor is easy to maintain, has a low noise level and low cost. However, due to significant disadvantages (large dimensions, low efficiency (efficiency), the complexity of the electrical control circuit, etc.), they are not used in washing machines now. They can be found only in old models such as SM-1.5 "TsNA" (Tambov plant "Revtrud"), "Donbass", "OKA" (Nizhny Novgorod plant named after Y. Sverdlov), "Riga", etc., manufactured before 2000 year.

Collector motors

Collector electric motors are motors that are currently installed on about 80% of washing machines (Vyatka-automatic machine, semi-automatic models of the Eureka series, etc.). Structurally, they are somewhat more complicated than induction motors, since, in addition to the stator and the collector rotor, they require a tachogenerator and current-conducting brushes. Collector motors have:

• small overall dimensions;
• significant starting moment;
• simple control scheme;
• high rotor speed, etc.

Important! At the same time, the collector electric motor requires regular maintenance due to the wear of the collector-brush assembly, and has a high noise level.

Inverter motors

Structurally, inverter (brushless) electric motors, as well as induction motors, consist of a stator and a rotor. However, thanks to the use of direct drive technology and a three-phase inverter type control circuit (the speed is controlled by a frequency converter), the developers managed to eliminate a number of connecting elements, which improved their operational characteristics. They differ from other types of engines:

• high efficiency;
• high power;
• long service life;
• low noise level, etc.

Of the shortcomings, experts note a more complex control scheme, which somewhat increases the cost of automatic washing machines (Indesit, LG, Ardo and their analogues).

Dismantling and connecting electric motors

When removing a used electric motor from the body of the washing machine, it is necessary to take into account some nuances.

removed with a capacitor... In this case, the capacitor must be discharged, otherwise you can get an electric shock.
1. On the stator of a low-voltage collector motor installed permanent magnets, alternately connected to the current source... On the body of such a motor there must be an information plate indicating the magnitude and polarity of the connected voltage.
2. Inverter motors dismantled together with the electronic control unit... On the body of the latter there is also a plate (sticker), which indicates the value of the supply voltage and its polarity.

Before starting the engine from the washing machine, you need to understand the purpose of its wires and connect them correctly. They have different colors from different manufacturers, so you must first "ring" them with a tester.

In homemade products, collector motors from washing machines are most often used. They usually have 6 wires. Wherein pins from the tachogenerator are practically not used... Their resistance to ringing is about 60-70 ohms. Having identified these wires, they are taken to the side and fastened with electrical tape (so as not to interfere).

The remaining conductors go to the stator and rotor (2 wires) and to the conductive brushes (2 wires). On the wiring diagrams, they are indicated by colored or numbered arrows. For example, "arrows 1" mark the wires leading to the brushes, and "arrows 2" - to the stator windings. The easiest way determine the conclusions coming from the brushes... They are called from the side of the contacts, after removing the graphite rods. The resistance of the stator winding wires is in the range of 12-35 ohms.

There are also motors with 3, 4 or 5 wires. In this case, a three-wire circuit is used in single-phase motors, where the starting winding (with a lower resistance) connected via a capacitor... In addition, one of the wires can be ground. Outputs that are not ringed can go to various sensors (for example, a temperature sensor, etc.). The circuit for switching on the electric motor is also important - a star or a triangle.

Having determined the pairs of wires coming from the rotor and stator, connect one by one from the stator winding and from the rotor brush. The remaining two wires are connected to the mains and test the performance of the electric motor.

Advice! For safety reasons, before connecting to the 220 volt mains, the engine must be securely fixed on a fixed base. This will avoid unintentional movement when power is applied.

Homemade products from the engine from the washing machine

The electric motor from the washing machine can be adapted as the main power unit in a variety of designs. Getting started, you must first of all decide on the parts that will be mounted on the shaft of this motor, and ensure their reliable fastening. To do this, it is necessary to equip the motor shaft with a suitable attachment.

Modification of the electric motor

The main problem that has to be solved when modifying the electric motor is the inconsistency of the bore holes of the parts that will be attached to the shaft with the diameter of the latter. To mate these parts, it is necessary to make a special adapter (flange). On the one hand, it must have a thread to install the part, and on the other, an element that allows the flange to be securely fixed to the motor shaft.

Most often, for the manufacture of such a flange, a piece of steel pipe with a length of no more than 20 mm and a diameter of 32 mm is used. A thread is cut at one of the ends of this pipe, the length of which must be at least twice the thickness of the nozzle to be installed.

Important! The thread must be cut in the opposite direction to the rotation of the motor shaft. Otherwise, the installed part will fly off, which is unsafe for the user.

The opposite end of the pipe is heated with a blowtorch and pressed onto the motor shaft. After cooling, the flange will be securely fixed. To strengthen it, it is advisable to drill a hole across the joint and additionally tighten the shaft and flange with a bolt and nut. Such revision will allow you to securely fix any nozzle on the motor shaft (a pulley for a belt drive to a compressor, grinding or cutting wheels, cutting blades, etc.). You can use an electric motor modified in this way when creating various homemade products.

To sharpen scissors, knives, drills and other cutting tools, the motor must be fixed to the workbench or other suitable surface. To do this, it is best to make an intermediate frame (stand), on which, using the standard mounting holes, install the engine. The design of the frame must ensure reliable fastening of the assembly to the workplace.

The next operation is setting the grindstone... To do this, you need to prepare three nuts with the appropriate thread and two suitable washers. One nut is screwed onto the flange until it stops, then a washer is put on, then an emery wheel and another washer. This whole "sandwich" is tightened with the second nut. The third nut is used to lock the threaded connection. On this, the creation of emery can be considered complete.

Advice! Such a device can be assembled using even a small electric motor from "Baby" type washing machines.

Other simple devices are made in a similar way, for example, a circular, a grinder (grinder), etc. But if the emery can be started simply by twisting it by hand (being careful), then when using more complex mechanisms made using an electric motor from old washing machine, a starting device is required. How to make such homemade products with your own hands will be discussed below.

By securely fixing the frame with the electric motor to the workbench, you can make a multifunctional lathe designed for processing wood blanks. It includes:

• headstock mounted directly on the shaft of the electric motor;
• tailstock, designed for reliable fastening of the workpiece being processed;
• a handyman providing convenient use of the tool (cutter, chisel, etc.).

The construction of a stationary sawmill begins with the manufacture of a special bed with a technological slot for a saw blade. An electric motor from a washing machine is then installed on it, having previously secured a small pulley for a drive belt on it. The large disc is mounted on the saw blade shaft. The pulleys are connected to each other by a V-shaped or grooved belt.

To make a feed cutter, in addition to the engine from the washing machine, you will also need its drum, in the back wall of which you need to make a hole for the electric motor shaft. Then, having installed the motor on the drum, the cutting elements (2 knives) are fixed on the shaft. The drum should be covered with a lid on top, otherwise the cut raw materials will fly out of it.

Conclusion

When purchasing a new washing machine, you should not throw the old unit in a landfill. Its constituent parts, and especially the engine, can be used to make handicrafts useful in the household, saving a certain amount of material resources on this.

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 on 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, 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.

1. Shaft rotation should be minimal. Motors with no more than 1,000 rpm are best suited.
2. The motor power must be between 100 W and 1 kW. The most commonly used motors are 400 watts.
3. It is desirable that he has paws for fastening.
4. 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 frame of the future mechanism... It can be made from thick wood board, wood board, suitable plastic, but thick metal board works best. The electric motor is fixed to it with the help of brackets, corners or clamps. The connection of the electric motor to the stone takes place through 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 that will be used in the grinding machine. However, if a lathe is not at hand, you can do without one. In the video below, you can find out how to make a flange for emery 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 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

Emery can be made 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 to 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 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 controller, which 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 grinder from the engine of the washing machine without protective cover is prohibited. It can be made from sheet metal 2.5 mm thick.

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 when it breaks, fragments do not fly into the operator.

Your favorite washing machine has already lived its life and you decided to send it to the trash heap? Take your time, because you can create different homemade products from the engine from the washing machine.

Spare parts

An automatic washing machine has a rather complex design. Even in the event of a breakdown, it contains the parts needed to make some homemade products. Let's see what can be made from the spare parts of an old washing machine.

The main spare part, of course, is the engine (motor)... If it works, then it can be used to make a generator, sharpener, lawn mower and other appliances. Disconnect the wires carefully, remove the motor from the body of the washing machine and save it.

The manhole cover can turn into a fancy window or a beautiful pet feeding bowl. You can also make a case for meters from durable glass.

For the construction of various homemade products, legs, springs and other small parts are useful. The body itself can become a wardrobe or a unique table.

Let's consider in more detail, what can be done with the motor.

Washing machine motor prices

washing machine motor

Types of motors

Asynchronous

The oldest type of engine, consisting of stationary stator and rotating rotor. The first serves as the basis and magnetic core for the structure, and the second creates the driving force of the drum. The entire motor is driven by the alternating magnetic field of the component parts.

Asynchronous motors have low torque, therefore, the drum often wiggles during operation. Other disadvantages are overall dimensions and modest efficiency. At the same time, they are noiseless, are cheap, and have a simple design.

An asynchronous motor is often found in low-power, low-power appliances.

There are two- and three-phase asynchronous motors. The first ones went out of production long ago, and they can only be found in very old designs.

Collector

The most common type of engine. They work well under both AC and DC voltage. Under the body with hidden rotor, stator, generatorthat provides rotation speed. On the collector terminals there are special brushes with which the rotor contacts the engine.

Note:If the rotor and stator are connected directly, the motor shaft will rotate clockwise. For the opposite direction, you need to change the connection diagram of the washing machine electric motor - connect the brushes towards the rotor.

Unlike their oversized predecessor, brushed motors are quite compact and high speed... They are universal: they work with both alternating and direct current. The main disadvantage of the collector motor is low wear resistance: due to the constant contact of the brushes with the collector, the brushes and the collector wear out quickly. If the former can be easily replaced with new ones, then replacing the collector will be costly.

Inverter

Most modern look of 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, simplicity of design, noiselessness, small dimensions.

However, all this in one motor is not a cheap pleasure: development, production, and therefore 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 on 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 come out of the tachogenerator and we will not need it during work. Finding them is quite easy - just measure their resistance: it should be about 70 ohms.

Using the same device, we find the pairs of the remaining contacts. Now we connect one of brushes to one of the wires, and we connect the second brush and another wire to the outputs of the winding. After connecting the motor from the washing machine to the mains, the appliance will start to rotate. To change the direction of rotation, just swap the brushes.

With older models, the situation is slightly different: after defining paired outputs, you need 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 using it.

Homemade

Homemade products from the motor are quite diverse: with it you can create t grinder, lawn mower, concrete mixer, juicer, potter's wheel and much more. Consider the manufacturing process of some of the listed devices.

Emery

One of the most common uses for an old engine. The assembly of the machine requires little 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 differ from each other, therefore you will need a third item to connect them... 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 whetstone.

It is necessary to cut the threads in the opposite direction of the movement of the motor shaft. We attach the shaft to the other end using a soldering iron.

Can be drilled at the connection point for greater reliability hole and screw a bolt there and a nut. We screw two pairs of nuts and washers onto the flange thread one by one, and finally we tighten the lock nut.

We fix the engine on the stand. The stand can be either an old table or a piece of thick board, or you can use hardware from the same washing machine from which the engine was removed to secure it.

Wood lathe

The power of the old engine is enough for slow processing of a cylindrical workpiece . To relieve the motor from side loads, you can attach a support to it.

Drum Grinder

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 pedestal.

Concrete mixer

Old washing machines, or "barrels", are easily converted into compact and practical concrete mixer... For this:

1. We take out the activator from the car.
2. Cut 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.

The homemade concrete mixer will work after you connect the motor from the washing machine to the mains. If the machine will be used to work with small volumes of building material, then the power of the old engine is sufficient. For larger volumes, it is recommended to connect a more powerful motor.

Feed cutter

To manufacture a feed cutter-grain crusher, you will need a barrel body and an engine from an automatic machine:

1. At the bottom of the case create a hole through which the finished feed will come out.
2. Similar to a concrete mixer create blades with knives. You need to choose the right size for them: there should be a small distance between them and the edges of the case.
3. Install the blades: one at the bottom of the body, and the other at a distance of 0.5 meters from its top. In order to achieve better performance of the DIY it is recommended to use a separate shaft for each blade so that they rotate in opposite directions.
4. Remains only cut holes on the cover, through which we will fill the 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 financial resources, because these simple machines are quite expensive. If done right, then a homemade lawn mower from the engine from a washing machine will be in no way inferior to the appliances on the shelves.

First, let's figure out what materials and tools we need:

• collector motor;
• compact yet durable wheels. These can be removed from strollers, toy cars. If there are none at hand, cut out wheels from a plastic profile;
• the base will require a thick piece of steel or regular saucepan lid;
• knives, discs;
• metal pipe;
• steel corners;
• copper wire, plug;
• switch;
• fastening materials;
• open-end, socket, keys;
• welding machine, grinder;
• a hammer;
• drill, screwdriver, pliers;
• soldering iron.

Getting started:

1. In the center of the base cut holes for the motor shaft. We install it with the shaft down.
2. We attach earlier manufactured sleeve 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, our homemade lawn mower's wires are not insulated. It is strictly not recommended to use such a device in the rain or for cutting off wet grass.

If you still want your machine to be operated in any weather, then reliably insulate the wires, and for the device assemble the small casing made of waterproof material. A metal bowl is suitable as a cover.

Generator

Tired of unexpected power outages? Want to create backup power supplywho will help you out at the right time? So why not create a generator from a washing machine engine with your own hands? The assembly process is quite complex, but the result is worth it.

An asynchronous motor will serve as the basis for the future generator. Before creating the generator, let's do some preparatory steps:

1. We disassemble the motor case... 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. Create a template for attaching magnets from a tin strip. We mark on it the places for placing 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 complete, we proceed to the assembly itself. We will need:

• sandpaper;
• cold welding;
• glue;
• rectifier;
• tester;
• battery;
• charge controller.

The assembly sequence is as follows:

1. We glue the template on the motor... We glue the magnets onto the template itself.
2. Make sure that the distance and angle between the magnets do not change. In the opposite case, voltage drops, a decrease in power or its complete inoperability are possible.
3. Free space between magnets filled with cold welding.
4. Moving on to grinding the engine surface.
5. We find a working winding with a tester. We leave its wires, and delete all the rest. We pass the wires through the rectifier. We connect their ends to the controller. We connect the controller to the battery.

A homemade generator from a washing machine engine is ready to use. An electric drill, screwdriver, or other similar tools are suitable for untwisting the device. 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 the operation of 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 time washing machine.

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 making 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. A piece of a 20-centimeter pipe will play its role. 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. Inside it, a steel bar should also be installed, 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. You need 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 no worse than 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 lower 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 you plan to use it for cutting wet grass, then carefully insulate all conductive parts.

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 by 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 luminaire 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 rather 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 working and starting windings. 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 applied 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 complicated design. 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

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 in good working order, the rotor will start rotating.

The 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.

Homemade products from the engine from the washing machine (video selection, photos, diagrams)

1. How to connect a motor from an old washing machine with or without a condenser

Not all "washing" motors will operate with a capacitor.

There are 2 main types of engines:
- with capacitor start (permanently switched on capacitor)
- with a starting relay.
As a rule, "capacitor" motors have three winding leads, power 100-120 W and rpm 2700 - 2850 (washing machine centrifuge motors).

And motors with a "start relay" have 4 outputs, power 180 W and revolutions 1370 - 1450 (washing machine activator drive)

Connecting a "capacitor" motor via the start button may result in a loss of power.
And the use of a permanently switched capacitor in a motor designed for a starting relay can lead to burnout of the windings!

2. Homemade emery from the washing machine engine

Today we will focus on converting an induction motor from a washing machine to a generator. In general, I have been interested in this issue for a long time, but there was no particular desire for reworking the electric motor, since at that time I did not see the scope of the generator. Since the beginning of the year, work has been going on on a new model of the ski lift. It's a good thing to own a lift, but it's much more fun to ride with music, so I quickly got the idea to make such a generator so that I could use it to charge the battery on the slope in winter.

I had three electric motors from the washing machine in store, and two of them are absolutely serviceable. Here is one of these asynchronous electric motors, and I decided to convert it into a generator.

Running a little ahead, I will say that the idea is neither mine nor new. I will only describe the process of converting an induction motor into a generator.

It was based on the 180-watt electric motor of a washing machine made in China in the early 90s of the last century.

I ordered magnets from NPK Magnets and Systems LLC, before I had already bought magnets when building a wind farm. Neodymium magnets, magnet size 20x10x5. The cost of 32 pieces of magnets with delivery is 1240 rubles.

Alteration of the rotor consisted in removing the core layer (deepening). Neodymium magnets will be installed in the resulting recess. At the beginning, a 2 mm core was removed on a lathe - a protrusion above the side cheeks. Then a 5 mm recess was made for neodymium magnets. The result of the rotor rework can be seen in the photo.

Having measured the circumference of the resulting rotor, the necessary calculations were made, after which a strip template was made of tin. Using a template, the rotor was divided into equal parts. Then neodymium magnets will be glued between the risks.

8 magnets were used per pole. In total, there are 4 poles on the rotor. With a compass and a marker, all magnets have been marked for convenience. The magnets were glued to the rotor with “Superglue”. I will say that this is a painstaking business. The magnets are very strong and had to be held tight when gluing. There were moments when the magnets came off, pinched fingers, and glue flew into the eyes. Therefore, you need to glue the magnets using protective glasses.

I decided to fill the cavity between the magnets with epoxy resin. For this, the rotor with magnets was wrapped in several layers of paper. The paper is secured with tape. The ends are plastered with plasticine for additional sealing. A hole has been cut in the shell. A neck is made around the hole made of plasticine. Epoxy resin was poured into the shell hole.

After the epoxy cured, the shell was removed. The rotor is clamped into a drill chuck for further processing. Sanding was carried out with medium grit sandpaper.

4 wires came out of the electric motor. I found a working winding, and cut the wires from the starting winding. I installed new bearings, since the old ones were spinning a little. The bolts tightening the body are also installed new.

The rectifier is assembled on D242 diodes; the “SOLAR” controller purchased several years ago on Ebay is used as a charging controller.

You can watch the generator tests in the video.

To charge the battery, 3-5 turns of the generator are enough. At maximum speed of the drill, 273 Volts were squeezed out of the generator. Alas, the sticking is decent, so it makes no sense to put such a generator on a wind turbine. Unless the wind turbine will be with a large propeller or gearbox.

The generator will stand on the ski lift. Field tests already this winter.
