Compressor Clutch: Description and Operation

Magnet Clutch:

MAGNET CLUTCH
The magnet clutch serve to transmit engine power to the compressor module. It is built into the compressor shaft. When current flow through the magnet clutch coil, the drive plate is attracted so that the pulley and compressor shaft rotate as a module. When the compressor is not in use, the pulley alone rotates freely.








Compressor Clutch "ON" Delay System
When the A/C switch and fan switch are turned ON, a signal is sent to the engine control module. The engine control module then judges whether the engine is in operation. If the engine is operating, the engine control module activates the A/C relay. The maximum clutch "ON" delay times is 0.8 seconds after the A/C relay is activated.
