Electrical generators and motors in which at steady-state the rotor and its electromagnetic field rotate at selectively different angular speeds

Patent number: 6047104

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.
