ABSTRACT:
A lightweight electromagnetic clutch adaptable for use with an air conditioning compressor including a rotatable electromagnetic coil and pulley assembly and an armature plate forming part of a magnetic flux circuit. An annular dish-shaped member is joined in back-to-back relation with a rotatable coil housing to provide a unitary flux carrying driven structure with the radially outer portion of each defining a driven pulley belt receiving groove. The radially inner portion of the dish-shaped member together with the coil housing inner wall and a support casing fixed tubular extension define a bearing cavity wherein the dish-shaped member and the bearing provide, with the housing, composite flux paths for the magnetic circuit.
