Connection diagram for the motor from the washing machine

Good motors are in washing machines, even when the latter breaks down and is thrown away - the motors are left and later used in the household (for example, for a mini-machine). Here we will consider a typical motor from an automatic washing machine (new and old type) and a diagram of its separate connection to 220 V. But first, let me lay out a little boring theory, which you can skip by moving on to the second, practical, part of the article.

Theory of operation of a 220 V electric motor

Asynchronous motors for single-phase networks are mainly motors with two-phase windings and an auxiliary phase taken from a capacitor. Such motors are used in household appliances. A similar motor is used, in particular, to drive a washing machine. In addition to two-phase winding motors, three-phase winding motors are sometimes used in some other household appliances.

During direct starting, the motor can receive a current from the network that significantly exceeds its rated value. This current is called the motor starting current, and its value varies in the region Ir = 5-7In .

One way to reduce the inrush current is to use a star-delta switch. A motor designed to operate the stator in a triangular connection at a given mains voltage is connected to the star system at the time of start-up:

Due to the reduced voltage supplied to the stator winding phase and the change in connections from delta to star, the current taken from the network will be reduced by three times compared to the starting current in a delta circuit. However, when connected to a star, the motor has three times less starting torque, which makes it impossible to use this method during heavy starting (with a heavy load).

What can be done from a washing machine

You can always find a use for an old washing machine, even if you don’t need any machines, mowers, or concrete mixers. By disassembling the machine into its component parts, it becomes possible to create even several things at the same time.

Tank door from a washing machine

The drum cover itself is already worth a lot. Cut with part of the front wall, the door will fit perfectly somewhere in a bathhouse, cellar or even in a doghouse.

DIY barbecue from a washing machine

History is silent about who came up with the idea of using the drum as a device for preparing barbecue. But today the most common and simplest thing you can make with your own hands from a washing machine is a barbecue. It happens like this:

the tank is pulled out of the body;
metal legs are screwed to it, for which any tubes, angles, or channels are used;
We put firewood (coal) inside the new grill, and put skewers or a barbecue grill on top.

Take note of the grill from the washing machine drum. A good kebab maker in a store is expensive. And here there is an opportunity to make it from already unnecessary things. By the way, if the tank is divided into two parts, you will even get two kebabs. These can be taken with you into nature for those who don’t have a summer house.

The second easiest thing is to make a lampshade or pouf. For the pouf, a circle is cut out of chipboard for the lid, and a pillow is attached to it. Wheels are screwed to the bottom. The lampshade has the opposite: the bottom is cut out and a textolite circle with a hole for attaching the socket is screwed into its place. The tank is suspended from the ceiling by three or four cables.

DIY smokehouse from a washing machine

Making a smokehouse from a tank is not difficult. The main element in this case is a large old saucepan, into which the tank completely fits.

If you don’t have a saucepan, but you really want to start production, you’ll have to buy a suitable one. A homemade grill with legs is installed at the bottom of the pan. The tank is placed on the grill.

Alder (birch, beech) sawdust is poured into the gap between the tank and the bottom of the pan. We also cover the top of the tank with a grate on which smoked products are hung on hooks. The smokehouse is installed away from residential premises and flammable materials.

Feather removal machine

The body of a washing machine is suitable for such a homemade product. This device will be needed by those who raise birds on their farm. Removing feathers from carcasses by hand is tedious, which is why people come up with all sorts of devices to help them.

To make a feather removal machine with your own hands, you will need a tank with a metal disk installed at the bottom.

The disk should be slightly smaller in diameter than the tank and at least three millimeters thick. Holes are drilled in the disk into which so-called rubber fingers are placed.

The disk must rotate, so it is connected to the motor shaft.

You'll have to buy fingers. If there are several species of birds, then the diameter of the fingers will be different. Fingers are stuck into the holes of the disk and into the walls of the tank. You need about 130 fingers, calculated every three centimeters. We leave the motor the same way it was connected to the tank. The scalded bird is held by the legs and lowered into the turned on machine.

A video on the Internet will tell you what else you can do with your own hands using a drum, housing or motor. There are enough crafts for every taste.

Capacitor for electric motor

For small motors (<1 kW), the value of the starting capacitor can be determined from the relationship:

C [uF] = (1800 x Pn) / U2

where Pn [W] – rated motor power, U [V] – supply voltage.

This formula is also suitable for calculating the starting capacitor value for single-phase start-phase motors.

For larger motors (>1kW) a capacitance of around 70uF/1kW is suggested. It is necessary to use starting capacitors with operating voltages of 400..630 V AC.

You can omit the calculations and simply connect a standard motor from the washing machine to 1 phase 220 V through a 7 microfarad capacitor connected between the required terminals. Connect the first power wire to the middle, and the second, depending on the direction of rotation, to one of the capacitor wires. The power drop will be 30% - this is in theory.

The issue of choosing a capacitor is easily resolved. Here are examples of capacitance values for different engine powers.

Pn [W] 90 120 180 250 370 550 750 1100 S [µF] 4 5 6 8 12 16 20 30

Useful: Screw, sliding and spring terminal blocks

The rotation power in the washing machine is the same in both directions. These are motors with a typical connection for a single-phase motor. The main winding is connected directly to 220 V and a phase winding is connected in parallel with it along with a series-connected capacitor. If you reverse the phase winding wires, the motor will rotate in the other direction, but the power will be slightly less. This circuit works during the spin cycle. The same for slow and fast rotations - the capacitance switches inside the washer from 7 µF to 16 µF. Read more about the capacitor here

Possible breakdowns

Now you know how to connect an electric motor to give it a whole new life, but a small incident may occur: the motor will not start. It is necessary to understand the reasons and find a way to solve the problem.

Check engine heating after running for 1 minute. In such a short period, the heat does not have time to transfer to all components and the place of active heating can be clearly fixed: the stator, bearing assembly, or something else.

The main factors for rapid heating are:

wear or contamination of the bearing;
increased capacitor capacity (only for asynchronous motor type).

Then we examine every 5 minutes of work; it is enough to do this 3 times. If the reason is the bearing, then it needs to be disassembled, lubricated or replaced. During further operation, we regularly monitor the heating of the motor. Avoid excessive overheating, as repairs can cause huge damage to your home budget.

Connecting the motor from the SMA

This motor contains two independent windings:

for synchronous speed 3000 rpm - two-phase winding.

for synchronous speed 500 rpm - symmetrical three-phase winding . The three-phase connection system allows you to change the rotation speed by switching the power supply to the winding.

An older type motor usually has 5 wires, black, blue, white, red and green. A series of measurements were carried out to determine the windings and the resistance between them:

Blue-black 85 Ohm
Blue-green 85 Ohm
Black-green 80 Ohm
White-blue 15 Ohm
White-red 30 Ohm

Connecting an old electric motor requires finding the starting winding using a multimeter.

ON - initial winding . It is designed to start the engine only and starts at the very beginning until the engine begins to rotate.
OB – field winding . This is the work winding that runs constantly and constantly turns the motor.
SB – button from which voltage is supplied to the starting coil and turned off when the engine starts.

Assembling a barbecue from a washing machine drum

A homemade barbecue from a washing machine drum can be used in the courtyard of a private house, at a dacha or on an outdoor picnic. Manufacturing is possible due to the fact that the drum body is made of durable stainless material, which has high properties to withstand high temperatures. Making a barbecue from a drum is quite easy and simple; all you need is a welding machine and a little time.

To make a barbecue, a washing machine drum of any size will do.

To start:

It is necessary to make a supporting part of the future barbecue, it is best that this part can be removed, this will allow you to move the barbecue to any convenient place.
To make the support, only non-flammable and durable material can be used.
The height of the leg under the barbecue can be done at your own discretion, as long as it is comfortable.

Many craftsmen use old metal flower stands for support. To make this device, drums from front-facing machines are suitable. If the machine is top-loading, you will have to use a grinder to cut off one of the sides.

A mobile smoker is made from a drum that is removed from a top-loading machine. All side openings of the drum must be closed with a steel sheet. This is necessary so that the smoke does not disperse in different directions. A chimney must be installed on top. This can be done after cutting a hole of the required diameter. The grate must be secured inside the drum. You can weld the grate yourself or take it from the stove. You can always use such a smokehouse. Such devices for cooking delicious meat and fish will be a godsend for people who like to save money without sacrificing their comfort.

Connecting the electric motor from a new washing machine

If you look at the terminal block with the wires on the front, usually the first two wires on the left are the tach wires, which measure and regulate the rotation speed of the washing machine motor. We don’t need them - they are crossed out with a cross.

In different models of washing machines, the wires differ in color, but the connection principle remains the same. You just need to find the necessary wires by testing them with a multimeter.

A working tachogenerator in a quiet state usually has a resistance of 50-100 Ohms. You will immediately find these wires and disconnect them.

If you need to change the engine speed in the opposite direction, simply drag the jumper to the other pins. Look at the diagrams to see what it looks like.

Two contacts go through the brushes to the rotor windings, and the other two contacts go to the stator winding. The remaining contacts are a sensor for measuring the motor rotation speed. The rotor and stator windings are connected in series and by changing the ends of one of the windings, you change the direction of rotation. Without an electronic regulator, the engine will accelerate to several thousand revolutions per minute (as at maximum spin).

How to use the engine

The electric motors that modern units, such as those from Indesit, are equipped with are quite reliable and durable. And even a part from an old washing machine of a brand like Vyatka can last long after the equipment itself has become hopelessly outdated.

Based on the engine from a washing machine, you can make a grinding machine

In a washing machine, an electric motor rotates the shaft, which drives the drum. If the part is removed from the unit, a wide variety of attachments can be attached to the shaft, resulting in new tools and accessories. The most common ways to use an electric motor are:

Sharpening apparatus (sharpening machine). It is considered the simplest option for using a motor. The engine is mounted on a flat surface, and a round sharpening stone is attached to the shaft. The machine can be used for sharpening knives, scissors or tools.
Concrete mixer. To make it, we use a motor and a tank from an old washing machine.
Special vibrator or vibrating table for the production of concrete products. The vibrations created by the motor can contribute to the shrinkage of concrete, and it is this property that is used in the manufacture of these tools.
Device for grinding pet food. To do this, it is enough to secure the knives on the shaft. This device can also be used to chop large volumes of feed, such as grass for cattle.

We have listed only a small part of the devices that can be obtained from a washing machine motor. In order to make one of them, or come up with your own application, you need to know how to connect the motor so that the winding does not burn out.

A circular saw

Using a circular saw, you can easily cut boards, plywood and much more.

A circular saw

Manufacturing process:

For the base you need to use a metal table. You need to attach several corners to it. The engine will be screwed to them later.
For convenience and safety of using the machine, a toggle switch is installed in a convenient place. If the motor jams, you can turn it off immediately.
Plywood plates are screwed over the engine. Thanks to this, chips will not fall on it. Small parts are cut out of plywood and fixed with self-tapping screws. The circular saw is ready.

Assembling a barbecue from a washing machine drum

To make a barbecue, a washing machine drum of any size will do.

To start:

It is necessary to make a supporting part of the future barbecue, it is best that this part can be removed, this will allow you to move the barbecue to any convenient place.
To make the support, only non-flammable and durable material can be used.
The height of the leg under the barbecue can be done at your own discretion, as long as it is comfortable.

Call the master

If you are unable to repair and replace the Indesit washing machine motor on your own, you need to seek help from a specialist. There are several ways to find a master:

According to the advertisement . Repairers place information about their services in newspapers, post them on poles, and deliver business cards to mailboxes.
Contact the service center . The main thing is that this organization establishes itself well in the locality.
By word of mouth . It is possible that relatives or friends have used a similar service in the recent past. If they recommend a professional, you can trust them.
Internet message boards . There are a lot of them on the Internet, so you can find a master in every city.

Most craftsmen do not charge money for a visit if the person agrees to pay for the repairs. This information needs to be clarified at the stage of calling a specialist. Before choosing a repairman, you need to study reviews of his work. Moreover, it is better to do this on a site other than the one on which he placed an advertisement about his services.

Approximate prices:

replacement of brushes – from 1400 rubles;
engine replacement or repair – from 2000 rubles.

As a rule, the brushes are guaranteed for 6 months, and the motor is 1 year. Prices do not include the cost of parts (if they need to be replaced).

Before agreeing to repair the engine, you need to clarify its final cost with a specialist. An honest master will immediately name the price. If there is a need for repairs, he can announce the estimated cost, but there will be no significant deviations from it.

A lot of important and useful information about repairing Indesit washing machines is presented in this section.

The first officially patented washing machine was made of wood and was a box with a frame, half filled with wooden balls. Laundry for washing and detergent were loaded inside and the frame was moved using a lever, which, in turn, made the balls move and grind the laundry.

The expression “soap opera” (“soap”) did not arise by chance. The very first series and shows that had a female audience were broadcast on television at a time when housewives did cleaning, ironing and laundry. In addition, to attract female viewers to the screens, commercials for detergents: soaps and powders were often played on air.

There is a washing machine “for bachelors”. Linen washed in such a unit does not need to be ironed at all! The thing is that the device does not have a drum: some things can be placed inside the container directly on hangers (for example, jackets and shirts), and smaller things (for example, underwear and socks) can be placed on special shelves.

History knows the fact that a kitten fell into the drum of a washing machine and, after going through a full wash cycle on the “Wool” program, got out of the unit unharmed. The only trouble for the pet was an allergy to washing powder.

In the 19th century, washing ladies' toilets took a lot of time. The dresses were first ripped open, and then each part was washed and dried separately so that the fabric did not become deformed. After washing, the clothes were sewn again.

Astronauts, while in Earth orbit, solve the problem of dirty things using an original method. Clothes are dropped from the spacecraft and burn up in the upper atmosphere.

Washing machines equipped with the “No Iron” or “Easy Iron” functions can wash clothes with little to no wrinkling. This effect is achieved through a special approach to spinning - it is performed at low speeds, with long pauses, and a small amount of water is retained in the tank.

For washing small items on the road or in a hotel, it is convenient to use a regular plastic bag. Socks or tights are kneaded inside a tied bag along with water and a small amount of detergent. This method allows you to pre-soak things and wash them without damaging the fabric or wasting a lot of powder and water.

There are a variety of balls that are used in the washing machine. Antistatic ones will prevent the fabric from sticking to the body after washing, balls with special loops will “comb” the lint and prevent the appearance of pills, and silicone ones with pimples will prevent fluff from matting when washing outerwear.
