Replacing and connecting the motor from the washing machine, wiring diagram

An electric motor is often called almost a heart, which is installed in household appliances. And this is not in vain, because it is thanks to the electric motor that the drum installed in the washing machine rotates. Many people doubt whether it is possible to connect the engine from the washer to another device with your own hands?

Electric motor from a broken washer

What can be done with the washing machine engine

To fulfill this is quite realistic, even if you practically do not understand such issues. For example, your Indesit brand washing machine has failed, while the engine (its power is 430 watts, and the developing speed reaches 11500 rpm) is still in working condition, and its engine life is still normal. In this case, it can be useful on the farm.

Here are some ideas that will help you apply or connect a new motor installed in a washing machine that has failed:

1. An elementary option will be the creation of a grinding machine. In each house, knives and scissors that need to be sharpened periodically grind and dull. To do this, carefully attach the electric motor to a stable surface, attach a special grinding stone or grinding wheel to the shaft and turn it on.
2. A good option is the manufacture of paving slabs. You can also make cinder blocks, and if there is a private sector, then a great idea is a vibrating table.
3. For residents of the villages that are engaged in the cultivation of birds, you can design a grinder and a grass mill from the engine from the washing machine.

Features of the motor - the key to success

Today, there are more than enough different options for how to give a new life to an old motor from a washing machine, if it still starts. And all these ideas are based on the features of the motor to rotate a variety of nozzles or provide movement of additional mechanisms. You can come up with an even more original version of using a removed engine, but in order to bring your idea to life, you need to understand how the engine is connected from the washing machine.

Some useful tips

When connecting the engine that was left from your old washing machine to another device, you need to keep in mind several important nuances of this process:

• motors are not connected using a capacitor;
  no starting winding required.

On the transfer case there are wires of various colors, which you just need to deal with:

• 2 white wires - when connected, they will not be useful, as they are responsible for the tachogenerator working normally;
• red and brown are intended to enable winding of the stator and rotor;
• green and gray - for connecting to special brushes made of graphite (most often the same can be said about the brushes of the engine of the Indesit washing machine, in case they need to be replaced).

Correct wiring is the key to the success of the motor

Keep in mind that different models of engines can have wires of different colors, but the principle of their connection is the same in all cases.To detect the pairs, it is necessary to ring the wires in turn (those: those that are designed for the tachogenerator must have a resistance of 60 to 70 Ohms). It is better to glue these wires with electrical tape aside from others, so as not to get confused. The remaining wires also need to ring to identify the pairs.

Wiring diagram

To continue work, you need to carefully study all the nuances of the electrical wiring diagram. Basically, it was made in great detail and understandable even for the most distant from the world of electrical tools of the home master.

Connecting the engine from the washer

Connecting or replacing the washing machine motor is actually quite simple. First of all, it is necessary to prepare the wires that will be used for the rotor, as well as for the stator. Make a special jumper, which should be limited with tape. Those two wires that remain connected directly to the network.

Remember! When you connect the motor, which remained from the old washing machine to 220, the device immediately begins to actively rotate. Therefore, before starting work, make sure that the motor stands firmly on one or another surface.

If you need to change the direction of revolutions, it will be enough that you throw the jumper on those contacts that remain. To turn the device on and off, you need to connect special buttons to the circuit. In order to do this, you need to use the appropriate schemes, which can easily be found on special sites.

Now we know how exactly you can connect the engine so that it can still be used long enough. But how can you improve the resulting device?

Speed ​​control

For proper operation, you need a speed control

The engine of the washing machine is characterized by a rather high rotation speed, so it is advisable to make a special regulator so that the hammer motor works in different speed modes without overheating. For this purpose, you can use the usual light intensity relay, but slightly modified.

It is necessary to remove the triac from the “washer” together with the radiator - the so-called semiconductor device (in electron control, it functions as a controlled switch).
Then you need to solder this device into the relay chip, replacing parts with low power. If you do not know all the nuances of this procedure, it is better to ask the help of a specialist (electronic engineer or computer specialist).

There are times when the engine does a new job without the help of a speed control.

Types of engines

Varieties of engines from washing machines

Asynchronous. You can remove it only with a capacitor, which are completely different for each model of a washing machine. It is not recommended to break the connection of such an engine with a battery if its case is sealed and formed of various metal or plastic.

Attention! An asynchronous motor can only be removed from the washing machine when the capacitor is completely discharged, as this can prevent electric shock.

Induction motor

Low voltage commutator type motor. It is characterized by the presence of regular magnets on the stator, which are alternately connected to a constant voltage current. On the case of such an engine there is a sticker on which the figure of the maximum allowable voltage is placed.
Electronic engine. This type of device must be disconnected only together with the electronic power supply unit (ECU), a sticker with the maximum permissible connection voltage is placed on its body. Pay attention to the polarity, because engines with this principle of operation do not have the necessary reverse.

Frequent breakdowns: what you can face

How to connect an electric motor from an old washing machine is now known. But there are situations when the engine does not start. What are the causes and solutions to such a nuisance?

Try to check what condition the motor is in after three minutes of operation. In such a short time, all the parts cannot heat up the same way, so you have the opportunity to identify the place of the malfunction, which will be too hot. This may be a bearing assembly, stator, etc.

Miscellaneous engine failures

The main reasons why this or that part is too hot can be the following:

• a clogged or failed bearing;
• excessively expanded capacitance of the capacitor.

Correct engine connection

For the correct connection of the engine, which remained from the old washer, a minimum amount of knowledge and a little effort is enough. Also for this purpose, a winding using a multimer is used. To detect the necessary wires, it is necessary to ring the winding. This will allow you to choose the right pair for the connection. Everything is done very simply. The multimeter is connected to one wire, and the second end of the device should take turns touching the other wires to find the right pair. It is also worth fixing in advance what is the magnitude of the resistance of the winding. In the future, this information will come in handy. After the end of the dialing procedure, you should get 2 windings that would have different resistance indicators.

These windings are divided into two completely different types. One has an indicator of working resistance. The second type of winding is one of the starting parts. It is known that the value of the resistance of the working winding should be less than the starting one. In order for the motor from the washing machine to work fully, you need to use either the button or a special starting relay. As a button, you can even take the one that is installed for the doorbell. The main thing is that she does not have a fixed contact.

New life of the old motor - other uses

The process of connecting the engine, which remained from the old washer is incredibly simple and easy. It is enough to find him the correct and useful application. Then he can serve you some more time. You can experiment and make really useful equipment that will simplify your life in other areas. A little imagination and skills are enough to make it work.
