How does an AC clutch work?
The A/C Clutch is an electromagnetic device that engages and disengages the AC compressor pulley from the compressor drive. The AC compressor is a pump that is driven by the engine crankshaft through a belt pulley. However, the compressor needs to run only when the air conditioner is turned on. The A/C clutch is fitted to the fan belt pulley. When the AC is turned on, the clutch is energized and it engages the armature plate of the compressor drive and the compressor belt, making the compressor drive rotate at the same speed as the engine. When the clutch is de-energized, the A/C clutch disengages the belt pulley and the compressor drive to stop the compressor.
