ABSTRACT:
A pump such as a vehicle air conditioner compressor has a compressor shaft, a continuously engine-driven flywheel and means such as an electromagnetic clutch for selectively coupling the flywheel to the shaft to operate the pump. The flywheel also provides a permanent magnet field which field rotates with the flywheel and induces in the windings of a relatively stationary annular stator assembly an electric voltage in response to the rotating magnetic field. The pump shaft, annular clutch actuating coil, annular stator assembly, and permanent magnet flywheel are all generally concentrically disposed and in the order stated. The flywheel is driven any time that the engine is running thereby inducing a voltage in the stator windings and that flywheel also drives the exemplary compressor when the clutch is actuated.
