ABSTRACT:
A rotating field, synchronized electric generator or motor in which the magnetic field that the armature produces can rotate relative to the stator at a speed significantly different from that of the armature, under electronic or other control that obviates the need for a mechanical torque-carrying gearbox that can be used for a similar purpose in a synchronized generator or motor.
