Electromagnetic coupling for motor vehicle air conditioning system compressor has rotor and coil arranged so that when coil is stimulated, armature is pulled towards rotor to make coupling

摘要

The coupling has a hub (6), a spring plate element (61) connected to the hub and an elastic element (63), an armature (5) coupled to the spring plate element by the elastic element, a rotor (4) and an electromagnetic coil (3) positioned relative to the armature. When the coil is stimulated, the armature is pulled towards the rotor so that the armature and rotor surfaces come into contact, connecting them with the armature and rotor and transferring forces between the rotor and hub.
