The washing machine can be used two types of electric motors.The first - the brush commutator motor windings with additional stimulation.Such electrical machines are installed at the belt drive rotation of the motor to the drum.Smooth speed control is performed by applying a voltage of varying size to the additional stator winding.In washing machines with direct drive AC motors are used with the rotor permanent magnet and a multi-pole stator collector.They speed change is due to the inclusion in the work of more or less poles, or by changing the frequency of the current in the three-phase supply network.

Removing the engine from the washing machine

The washing machine motor is located at the bottom of the device from the rear.To gain access to the site of repair is necessary to
remove the auditing cover by unscrewing a few screws.In machines with a belt drive motor is mounted to a metal frame using pins or bolts.Electrical connection is made through a quick-terminals.Engines in cars direct drive have a more complex structure, as are themselves part of the washing tub.Their stator bolted to the frame of the washing machine, the rotor also has a rigid attachment to the basket, which is very often a one-piece.That is why the engine must be removed along with the tank.

Check multipolar phase motor

In most cases, checking the engine of a washing machine with direct drive can not be made without a special bench and laboratory equipment.The best way to find a fault in this case is the service menu of the machine or the frequency converter, the placement of which can vary depending on the model.According to the error code displayed on the screen can be diagnosed Coiled-circuit, open circuit supply, brush wear and other faults.

Check commutator motor

In most cases, the engine is disconnected group of several conductors, among them: the beginning and ends of stator and rotor windings and wire control circuit.To verify that the motor should be connected in series stator and the rotor, and the file on the ends of the mains voltage through the additional ballast, in which role can perform heater or other resistance in electrical capacity of at least 500 watts.If there is a rotation of the engine in the normal mode and there is no strong heating of the ballast, then the likelihood is high that the engine is all right and the winding are not violated.The reason may be in a strong brush wear or damage to the collector, broken wire or faulty control tacho.Such failure can be determined only with the full dismantling of the engine.
