ABSTRACT:
An adjustable speed drive system is provided which employs a unique induction machine which includes a rotor assembly mounted on a shaft, and associated cooperative first and second stators. The two stators are angularly adjustable, relative to each other, about the axis of the shaft. The net excitation of the rotor and thus the operating point of the machine on the torque-speed curve of a load on the shaft of the machine is a function of the relative angular displacement of the two stators. A third stator may be employed to enhance the efficiency of the machine by feeding excess rotor power back into the power line.
