If you spin the stator of an AC induction motor than would the rotation of the rotor increase? Or would it have a different affect such as moving with a higher force?
A standard induction motor has to turn at the speed determined by the current frequency. If you attempt to apply external torque to drive it faster it will act as a brake resisting that torque. If you apply sufficient torque to force the rotor out of phase with the driving current it would effectively stall ( the "braking force" dropping way off and or becoming erratic )
