What is the principle of the single-phase AC motor in the washing machine?
The motor of the washing machine should be called: capacitance type single-phase asynchronous motor. The principle is a series capacitor in the amount of the starting winding, the voltage and current of capacitor lags behind its 90 degree, it will produce a magnetic field in the stator, the motor rotating motor! Static centrifugal switch is turned on when the electric starting capacitor in after starting work, when the rotor speed reaches the rated value of 70% to 80% when the centrifugal switch will automatically jump, starting capacitor to complete the task, and disconnected. The running capacitor is connected to the starting winding to participate in the operation. This method is generally used in air compressors, cutting machines, woodworking machines and other heavy load and unstable place.

Single-phase AC motor principle: with single-phase capacitor type motor: single-phase motor has two windings, namely starting winding and running winding. The two windings are 90 degrees apart in space. A capacitor with large capacity is connected in series on the starting windingWhen the running winding and the starting winding pass through the single-phase alternating current, the current in the starting winding is 90 times higher than the current of the running winding in time by the action of the capacitor, and the maximum value is reached first. Two of the same pulse magnetic field is formed in time and space, so that a rotating magnetic field produces the air gap between the stator and the rotor, the rotating magnetic field, the induced current in the rotor current, and rotating magnetic field interact to produce electromagnetic torque, the motor rotation.
