How do I check the motor of the washing machine?

In the washing machine, the most important role is played by the motor, in fact, as in all other devices. But what to do in the event that you have a suspicion that the engine has broken down - how to check the motor of the washing machine? This will be discussed in this article.

Determine what happened to the

engine It can be said with certainty that this is the most unpleasant failure that entails a complete failure of household appliances and large expenses for its repair or for the purchase of new equipment. In order to check the motor of the washing machine for an open or short circuit of the rotor winding, in order to prove or disprove the breakdown, you will have to use the multimeter:

1. Turn your multimeter to the resistance measurement state.
2. Then measure the resistance between absolutely all adjacent lamellae. The landmark is simple - it should be everywhere equal, namely within 20-200 ohms.

Important! In the event that a breakage occurs, the resistance will be maximum. During the interturn closure, the total resistance of the entire winding will be much less.

Check the rotor of the engine

To check the electric motor of the washing machine for the iron package:

1. Switch the multimeter to the buzzer mode.
2. After this, connect one end together with the iron of the rotor, and the second one alternately move along the lamellae.

Important! The multimeter should not emit any signal.

Now you have to check the stator winding to find or not find the interturn closure. To do this:

1. With a multimeter in a special buzzer mode, alternately close each other absolutely all the ends of the wiring.
2. The multimeter must be "silent".

Important! In case you saw or heard the multimeter signal, it means that you have found the inter-turn short circuit.

When you find a short circuit in order to check the wire breakdown on the case:

• , close one end of the multimeter;
• the second one in turn, short-circuit to the wiring.

The signal should be absent.

Important! If it is, it means that the wires are broken insulation integrity and that it is punched on the body. In this case, your washing machine can sometimes be electrocuted.

We check the entire stator winding of your engine

If you find an open or short circuit of the windings, then starting to repair such a motor makes no sense. Naturally, there are options to rewind the winding, but this action will cost a little more than buying a new one. That's why with such a malfunction your motor needs to be replaced completely or the part that is faulty. The latter option is available, provided that it is possible to purchase such, for example, only a rotor or only a stator.

Overview of

Engine Varieties In any automatic washing machine, the drum rotates. For this, an engine is used.

What they are:

• Collector - used by equipment manufacturers Ariston, Indesit, Electrolux, Kandy, Zanussi, Samsung, Veko;
• Asynchronous single-phase - used in Siemens, Bosch, Mile washers, as well as some of Ardo models;
• Direct current - Aeg, as well as Asko;
• Brushless, that is, with direct drive - modern Lg, as well as some models of the company Samsung.

Malfunctions of the collector and asynchronous motor

Since these motors are used by most manufacturers, respectively - the need to check the motor of the washing machine occurs more often, we will consider possible causes of faults and types of malfunctions.

Frequent phenomena:

1. Damage, as well as brush wear. Characteristic indicators - loss of power during a large load of laundry, during the sparking burnt odor.
2. Closure, as well as breaks in the rotor and stator windings. Decrease in power, increase in temperature, well, and as a consequence - the thermostat is protected.
3. Wear as well as delamination of the collector sipes. In this case there is heating of the case, the appearance of sparks. We check the resistance of neighboring lamellas with a tester. It should be the same approximately 0.2 ohms. During winding, the winding may break.

Important! Various faults in the collector motors are caused by the following reasons:

• inter-turn closure or breaks in the rotor windings or stator;
• wear of brushes;
• defects of the collector sipes, for example their detachment.

In fact, there can be much more reasons, but we will dwell only on the above, as the most characteristic, and often encountered.

Wear of collector brushes

Wear brushes on the surface of the collector motor must be replaced immediately, ideally - on the original. But what if they do not exist?

Wear of brushes in most cases can be determined by an external inspection or by how much the engine's collector sparkles intensively - as under load, that is.in the tank of the machine there is linen, and without this load - in this case there are abundant sparking, but not along the perimeter of the collector.

Important! You should definitely take into account the fact that a similar phenomenon occurs when new brushes are not yet attached to the collector itself.

Slot failure

Due to the fact that lamellas are broken, they can lose contact with the section of the entire rotor winding. They can too quickly and strongly heat up, and in some cases also exfoliate. The lamellas are fixed by means of an adhesive on the manifold. And the electrical connection together with the sections of the rotor winding produce special hooks.

Important! The most frequent variant of the failure of this engine part is the breaking of the cord in the rotary section itself in those places where it joins the lamella.

It will be much worse if, due to excessive overheating, the lamella has peeled off. This failure occurs due to the winding closure in the section, between the lamellas, and also the rotor jamming.

Important! Such a defect is due to the fact that the electricity passes through the lamellas, which is much higher than the working level.

This defect can occur at the moment when the bearings are knocked down or when washing started inside the vertical washing machine and the drum shutter was not locked in the closed position.

Important! Most often, a similar defect in the lamellas says that there may be some other breakdown of the electric motor, or the machine is not operated for its intended purpose.

Can this be fixed?

1. A small detachment, which does not exceed half a millimeter, is retracted with the aid of a recess of the collector by means of a special machine.
2. After that, carefully inspect and clean absolutely all parts of the part from dust, chips, eliminate burrs.

Important! To determine the presence of such a malfunction, you can slowly rotate the rotor with your own hands. In the event that you hear a characteristic crack, this means that most likely, this breakage is present.

Interturning faults, breakage in rotor windings or stator

In the case of breaks or alternating windings of windings, characteristic defects may appear - the engine does not work, that is, the breakage occurred in the stator windings.

This defect is also possible by the factor of engine case overheating due to inter-turn faults inside the windings. During a significant temperature of the shell, as a rule it is more than 90 ° C, a special mechanism must necessarily work - a safety thermostat. It destroys the engine power circuit.

Important! Normal is the temperature of the engine casing, which does not exceed 70-80 ° C.This temperature reaches during the long washing cycles of your washing machine.

Now you know how to check the motor of the washing machine and what can be detected as a result of this testing technique. We hope that your suspicions were reckless, and the reason for the malfunction of the expensive washing machine was covered in more banal malfunctions, cheap in repair.
