Compressor Clutch: Description and Operation
OPERATIONThe clutch assembly consists of a stationary electromagnetic coil, hub bearing pulley assembly, and clutch plate.
The electromagnetic coil and pulley are retained on the compressor with snap rings. The clutch plate is mounted on the compressor shaft and secured with a nut.
When the compressor is not operating, the pulley free wheels on the hub bearing which is part of the pulley. When the coil is energized the plate is magnetically engaged with the pulley and turns the compressor shaft.
