Abstract
The present invention relates to a field coil assembly of an electromagnetic clutch for a compressor. The present invention comprises a core, and a coilinstalled to the coreand formed by winding a unit wire. At this time, the unit wirewound on the coilis made of aluminum, and an area ratio R of an inner sectional area M of the coreto a cross-sectional area of the unit wireis 400 to 640. According to the present invention as above, since the unit wireused for the coilis made of aluminum with a small specific weight and low price rather than copper, the weight of the field coil assemblyis decreased to improve fuel efficiency of a vehicle and decrease a production cost of the field coil assembly
