ABSTRACT:
A permanent magnet, alternating current motor having a variable hysteresis output coupling has an annular permanent magnet rotor caused to rotate within a stator structure. This permanent magnet rotor is capable of being shifted laterally to engage or disengage a hysteresis drag cup output device. With this arrangement either an off-on output torque can be provided, or the output torque can be modulated.
