Answer Posted / gundra chakrababu
if the stator and rotor have same umber of poles,the harmonics produced in them are also of the same order.as these harmonics slip past each other, pulsating torques are produced,if the speed of these harmonics coincide,the stator & rotor poles would lock each other.this condition is called "cogging".under this condition,the motor would crawl at a subsynchronous speed and develops a synchronous torque.
