<p>In an electromagnetic clutch, for a refrigerant compressor for an automotive air-conditioning system, there are at least two electromagnetic coils (501,502) located axially adjacent and connected in series between a battery (205) and earth. The junction (208) of the coils is connected to a control circuit (200) arranged to disconnect the coils from the battery when a thermal difference between the coils (501,502) is detected due to excessive slipping of the clutch friction surfaces (331,71). <IMAGE></p> |
