  • What is working principle of washing machine?

    A motor causes the drum to rotate in half revolutions, causing the clothes to be tossed from side to side. A thermostat heats the water to a temperature suitable for the fabric and the degree of soiling, i.e., 40°C for normal washing and 90°C for heavy soiled cotton. The soiled water is drained out of the machine through the perforated drum and empties into the waste pipe. The drum is filled ...

  • Washing machine drain motor structure and working

    Let's take a look at the structure and working principle of the drain motor of the washing machine. Drainage motor The drainage motor is mainly composed of a miniature synchronous motor, a variable speed gear, a traction wire rope, and a stroke switch. When draining, the computer board (or programmable controller) supplies power to the miniature synchronous motor of the drainage motor.

  • AC motor - Wikipedia

    Operating principles. The two main types of AC motors are induction motors and synchronous motors. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding. As a result, the induction motor cannot produce torque near synchronous speed ...
