Vehicle air conditioner compressor - has flywheel coupled to shaft by electromagnetic clutch and providing permanent magnet field to induce voltage in stator

摘要

The vehicle air conditioning compressor has a compressor shaft, a continuously driven flywheel and an electromagnetic clutch for selectively coupling the flywheel to the shaft to operate the pump. The flywheel also provides a permanent magnetic 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.
