The torque produced by the motor drops to zero at 0% slip and thus, for all practical purposes, an induction motor cannot actually achieve synchronous speed. Conversely, if the rotor is turned in the opposite direction with respect to the stator field, but at synchronous frequency, the induced voltages will have twice the magnitude and ...
