Engines from washing machines. Connecting the engine from the washing machine. What to make of the engine from an old washing machine?

The engines from the abandoned washing machines can become the basis of new devices, the work of which is built on rotation. For example, you can make an emery for sharpening knives, functioning from electricity, as well as a mixer and much more. This will be discussed in the article.

Types of engines

The shaft of the washing machine rotates by the motor. He has various design features. The motor can be a collector, asynchronous or electronic type.

Motors from washing machines are shot in different ways. First of all it is necessary to disconnect the washing machine from electric power, sewerage network and water supply. In this condition, the unit must be at least 10 hours. During this time, the capacitor will be discharged. Only after this you can proceed to remove the motor.

How do I remove an asynchronous motor?

Wires connecting the asynchronous motor and capacitor should not be cut off. The battery is pulled out with the engine. There are many kinds of batteries. It can look like a metal or plastic box. Typically, the battery is a sealed construction. It contains one or more capacitors, the connection between which is parallel.

The connection diagram of the unit is also different. The winding can be connected directly to the network. Another modification involves the passage of current through the capacitor. The existing scheme can not be changed. It needs to be connected to the power supply, and the induction motor starts its rotation.

Do not touch the engine parts until the capacitor is depleted.

How to dismantle the collector type of motor?

The motor from the washing machine of the collector circuit belongs to the category of low-voltage modifications. The stator contains permanent magnets connected to a constant voltage.

On the motor there is a sticker on which the required voltage is indicated. Connecting the engine from the washing machine collector configuration involves supplying this particular indicator.

Electronic motor

The electronic circuit is taken from the washing machine together with the control unit. On the body of the unit, the voltage is indicated, to which the motor should be connected. It is very important to observe the polarity, since this type of motor does not assume a reverse.

It happens that the connection of the engine from the washing machine is not carried out immediately. In this case, it is recommended to find other conclusions, to which the zero phase or logical unit is fed. After this, the unit starts to rotate.

How to connect the electric motor of a modern washing machine?

If you decide what to do with the old motor, then you probably will be interested in how to connect the electric motor to a voltage of 220 V.

Before proceeding to the direct connection, it is advisable to familiarize yourself with the electrical circuit. First of all pay attention to the wires coming from the engine. At first glance, there are a lot of them, but in fact not all of them will be needed. For work only rotor and stator wires will be needed.

How to deal with the wires?

If you look at the front of the shoe, then, as a rule, the first two wires on the left are related to the pick-up device. They are responsible for regulating the engine speed of the washing machine. These wires are not needed for work.

Then follow stator wires of red and brown color and rotor wires of gray and green color. These four wires are also needed to connect the motor.

In different modifications of washing machines, the wires will differ in color, but the principle of their connection remains unchanged. Just find the right ones by calling them with a multimeter. To this end, you must switch the device to measure the resistance force. One probe should touch the first wire, and the second one should look for the pair.

At the tacho-generator, which is in working condition, the resistance is 70 Ohm. These wires are noticeable, but they are not needed.

Washing machine

How to connect the engine from the washing machine? Once the necessary wires have been found, they must be connected.

For this purpose, connect one end of the stator winding to the rotor brush. It would be better to make a jumper and isolate it. After this, the end of the rotor winding and the wire that leads to the brush remain. These two ends are connected to the network. As soon as voltage is applied to these wires, the motor will start to rotate.

The engines from washing machines have a high level of power, so you should be careful not to injure yourself. It is advisable to mount the motor on a flat surface.

If you want the direction of rotation of the engine to change, you should throw the jumper on the other pins and change the wires of the rotor brushes in some places.

If everything is done correctly, the motor will start its rotation. If this does not happen, then you should check the working state of the engine and only after that make any conclusions.

To connect the motor of a modern washing machine is not difficult, which can not be said about the old models. Their scheme is different.

How to connect the motor of the old unit?

The engines from washing machines, which have served for many years, are harder to connect. To find the wires, you should ring all the motor windings. So you will find couples.

The multimeter is in the resistance measurement mode . One end should touch the first wire, and the second in turn to look for his pair. The resistance of the winding is advised to be recorded. They will be needed.

Then the second pair of wires is searched in the same way and the resistance index is fixed. There are two windings with different resistance values. It should be determined which of them is the working winding, and which is the starting winding. The tip is resistance. The winding, in which it is smaller, is working.

Many believe that the launch of such an engine is by means of a capacitor. This is a wrong opinion, since the capacitor is used in engines of another modification, in which there is no starting winding. In this case, it can help burn the motor during its operation.

To start an engine of this type, you need a button or relay to start. The button must be equipped with a non-latching contact. You can use the button from the doorbell.

The scheme of connecting the engine from the washing machine is as follows: 220 V is applied to the excitation winding (OB). The same voltage is applied to the starting circuit (PO), only to start the engine for a short period of time. To disable it, use the (SB) button.

After all the manipulations, it is enough to start the engine. For this purpose, the SB button is pressed and, as soon as the motor starts spinning, is released.

To ensure the reverse (rotation of the motor in the other direction), the contacts of the winding should be exchanged.

Is it possible to give a second life to the motor of an old washing machine?

Many are wondering what to make of the engine from the washing machine. The working motor of the collector circuit is suitable for the construction of various devices. Some of them will be discussed in this article.

Grinder

It can be made by any man if he has a motor from the washing machine "Indesit", "Ariston" and any other model.

When attaching the grinding stone to the engine, the manufacturer may encounter a problem: the diameter of the stone hole does not correspond to the diameter of the motor shaft. It is advisable to use an additional part, which is ground on a lathe. Making such an adapter is not difficult. The main thing is to know the diameter of the shaft. In the presence there should be not only an adapter. Also it is necessary to prepare a nut, a washer and a special bolt.

The thread on the nut is cut depending on the direction in which the rotation of the motor is directed. For clockwise rotation, the left-hand thread is made, and the right-hand thread is made counter-clockwise. If you do not adhere to this rule, then the stone will start to fly, as the process will go on unwinding.

If there is a nut with a thread that is not suitable in the direction, you can change the direction of rotation. For this purpose, the winding wires change places.

You can set the motor to the opposite rotation without using a capacitor. After the working winding is connected to a voltage of 220 V, the stone abruptly scrolls to the desired direction.

The speed indicator of the grindstone should not exceed 3000 per minute. Otherwise, the stone will break.

When using such an aggregate at home, experts recommend using a motor whose frequency is 1000 rpm.

The grinding machine made by own hands, it is necessary to equip with additional elements. They will serve as protection against dust and stone fragments during work.

A piece of metal with a thickness of about 2 mm can be used as a casing.

How to make a vibrating table?

Using the engine from the washing machine machine "Ariston", "Ardo", etc., you can make a vibrating table. It is needed for the production of tiles for laying out garden paths.

The construction of the vibrating table is not difficult. It includes a flat plate, fastened to the base by movable joints. The operation of the collector motor causes the plate to move. As a result, air is pumped out of the concrete, which makes the quality of the tile higher.

The position of the collector motor is set according to the scheme. If you install it in the wrong place, the table will not be able to function properly, and the production of quality tiles will not work.

How to make a concrete mixer?

The engine from the old washing machine can also be used to create a concrete mixer. This product is not intended for industrial volumes, but it is quite suitable for household needs.

To make a concrete mixer from an old washing machine, you need not only a motor, but also a tank. In the capacity of the tank with the activator inserted a pair of blades, which are similar to the letter "P". From the tank, the standard activator should be removed first. It is not difficult to make details. For this purpose, a strip of steel with a thickness of about 5 mm is taken. It cuts off the right amount of material that bends. Two blades are arranged so that they make a right angle. They are connected to the tank through the hole where the activator was located.

The hole in the tank, through which the water is drained, must be closed. With the correct assembly of the structure, you can connect the motor.

Depending on how much concrete you are going to mix, the engine's power rating is selected. With a small volume, you can mount a motor with one phase. If mixing of large volumes of concrete is expected, a more powerful unit is installed

It should be remembered about the temporary transfer. It must be replaced with a reducer. It will reduce the engine speed.
