Electrical motor system

A plurality of motors (14, 16, 18) for use in driving accessories (15, 17, 19) on a vehicle, are each powered by three-phase current. A single controller (12) controls the supply three-phase current to the plurality of motors. In another aspect of the invention, pseudothree-phase current is created from a direct current voltage source (42). A chopping circuit (40) chops the voltage into a plurality of pulses, and a phase shift circuit (64) then creates phase-shifted power signals from those pulses. The present invention thus enables the use of three-phase alternating current motors on a vehicle to drive accessories. This reduces the cost and size of the required motors.
