Beschreibung
Zusammenfassung:	An electromagnetic clutch for a compressor in an air conditioning system, having a rotor 2 for receiving a rotating movement from its source, a hub 12 in connection with a rotating shaft of the compressor, a coil housing 4 for storing a coil spool 14 on which an electromagnetic coil is wound, and an armature 8 which is attracted to a frictional surface 2a of the rotor 2 under the effect of an electromagnetic attracting force generated by the electromagnetic coil 5. The coil spool 14 has an inclined surface at an inner corner location which is located adjacent the frictional surface 2a of the rotor 2. The coil spool has a recess at a location where the inclined surface is formed, in which recess a temperature fuse is arranged. The temperature fuse is broken under a condition that the temperature is higher than a predetermined value, thereby de-energizing the electromagnetic coil 5.
