ABSTRACT:
An auxiliary system includes a plurality of devices that are driven by ac motors. A plurality of independently controllable isolators couple phase windings of the ac motors directly to phase windings of the electric generator. When an isolator connects the phase windings of its corresponding ac motor to the windings of the electric generator, the ac motor is operated directly on a high frequency unconverted output of the electric generator. Motor speed is determined by the number of poles on the ac motor relative to the number of poles of the electric generator. Pole-switching allows the speed of the motor to be varied.
