The working principle is that when the car air conditioner switch is turned on, the current passes through the electromagnetic coil of the electromagnetic clutch, and the electromagnetic coil generates electromagnetic suction, which makes the driving disc of the compressor combine with the pulley, and transmits the torque of the engine to the compressor shaft to make the compressor shaft rotate. When the air conditioner switch is turned off, the suction force of the electromagnetic coil disappears, and under the action of the spring plate, the drive disc and the pulley are disengaged, and the compressor stops working.
