WebApr 29, 2014 · An induction motor never spins at synchronous speed. A motor spinning at constant speed must be producing enough accelerating torque to overcome the decelerating torque of the load. Since an induction motor must slip to provide torque, the full-load speed will always be less than synchronous speed. Web⇒ A 3-phase synchronous motor is running clockwise. If the direction of its field current is reversed the motor will stop the motor continue to run in the same direction the winding of the motor will burn the motor will run in the reverse direction ⇒ Synchronous motor always runs at the synchronous speed less than synchronous speed
