Answer Posted / shankar
Have you ever heard about cogging in induction motors. When the number of stator slots is equal to the number of rotor slots, forces due to reluctance are produced which dominates the accelerating starting torque of induction motor and hence reduces it. So the motor wont rotate when the no of stator slots is equal to number of rotor slots. This phenomenon in induction motor is called Cogging.
This does not occur in slip ring induction motors. you know why?? because of high starting torque.
