Answer : The rotor of a hysteresis motor is made of chrome steel.

Answer : Locked rotor current of a shaded pole motor is slightly more than full load current.

Description : Describe with neat sketch working of hysteresis motor.

Answer : Working: When stator is energized with single phase ac supply, rotating magnetic field is produced because of starting (auxiliary) and main windings, which remain in circuit permanently. The ... the principle of magnetic locking this motor either rotates at synchronous speed or not at all.

Answer : A hysteresis motor works on the principle of hysteresis loss.

Answer : The direction of rotation of an hysteresis motor is determined by position of shaded pole with respect to main pole.
