Answer Posted / dileep kumar
emf induced in the rotor conductors is dynamically induced emfs.cndotion for dynamically induced emf is there z relative motion between flux and rotor conductors. if induction motor is rotating at shynchronous speed , then relative velocity is zero & no emf production & torque is proportional to the square of the induced voltage so no torque which can turn or twist the rotor is zefo thats why induction motor never rotate at synchronous speed
