Electro-mechanical device

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