why the no.of slots in stator in not equal to the no. of
stator in rotor in induction motor????

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.
