From the time of starting until it reaches synchronous speed, the motor produces a synchronizing. The torque in a hysteresis motor is produced due to hysteresis and eddy current induced in the rotor by the action of the rotating flux of the stator windings. It is a singlephase motor whose operation depends upon the hysteresis effect i. In its simplest form, the rotor of a hysteresis motor is a smooth cylindrical tube of high hysteresis loss permanent magnet material without windings or slots. To develop synchronising revolving field from single phase supply, the stator of hysteresis motor is designed accordingly. The stator is wounded with main and auxiliary windings so as to produce rotating magnetic field.
