Abstract: Disclosed is a field coil assembly of an electromagnetic clutch including a bobbin from which lead wires, which are both ends of a coil made of an aluminum-based material, protrude outward, a core that surrounds the bobbin such that the lead wires are exposed, a bobbin terminal installed at the bobbin while being adjacent to the lead wire of the coil, and a connector coupled to the core and including a lead wire terminal. The lead wires of the coil are connected to the bobbin terminal through heating and pressing.

Abstract: A disk and hub assembly for an electromagnetic clutch, comprising: a plate including a stopper, which is projected from a face thereof and having a bolt through hole, and an inner ring portion folded from the outer periphery of the plate; a hub including a hub body, which is perforated through both ends and has a coupling hole to be coupled to a drive shaft of a compressor, a seating space for receiving and seating the stopper and a flange outwardly extended from an end of the hub body to be coupled to the plate; an outer including an outer ring portion surrounding the inner ring portion at a predetermined interval and a flange outwardly and angularly folded from the outer ring portion; a damper rubber received between the inner ring portion and the outer ring portion; and a disk coupled to the flange of the outer.

Abstract: A clutch for a compressor includes a pulley rotatably installed on a main body of the compressor to be coaxial with a rotary shaft of the compressor, a hub member fixed at the rotary shaft and having a flange through which a plurality of recesses are formed at its outer peripheral surface at intervals of a predetermined distance, elastic members, parts of which are received to the respective recesses to be supported, and other parts of which protrude from the recesses, an outer ring member for supporting the protruding parts of the elastic members, a stopper member for supporting the protruding parts of the elastic members together with the outer ring member to prevent the elastic members from moving, and a disk fixed on the outer ring member, for transmitting power by selectively being tightly coupled to or separated from a frictional surface of the pulley.
