[0002] In automotive air conditioning systems, electromagnetic clutches play a key role in power transmission.

[0003] When the air conditioning system needs to work, the electromagnetic clutch will connect the current, generate magnetic force, attract the pulley friction disc and the compressor main shaft to combine tightly, thereby transmitting the power of the engine to the compressor and driving it to perform refrigeration work.
