AC-Magnetic Clutch and Parts

Explanation of operation Magnetic coupling
The magnetic coupling, also called clutch, is the circuit between a compressor that is in operation and a compressor that is not in operation. By supplying the magnet with voltage, the front plate is attracted from the magnetic coupling to this front plate, also called hub, which is mounted on the crankshaft of the compressor, the compressor starts working.
So when the motor to which the AC Compressor is mounted, the air conditioning can be switched on by operating the on/off switch or it is switched on by automatic setting. The operation can also be stopped if no blower or fan is switched on yet, so it must also be switched on or it will switch on automatically if it is activated as an auto setting.
If the temperature is reached that has been set manually or automatically, the magnetic coupling will be switched off, if the temperature rises in the room, the magnetic coupling will be switched on again, so that the compressor works.
Check operation of magnetic clutch after disassembly of compressor from vehicle:
1. Check that the bearing runs smoothly and without noise.
2. Check whether there is play on the bearing and the pulley.
3. Check whether there is any play or contact surfaces at the faceplate/hub and pulley.
4. Apply voltage to the magnetic clutch, knowing what the power supply is 12V or 24V. The front plate is pulled in, the pulley and front plate have become one and the crankshaft now turns with it. If not magnet defective.
Replace complete clutch at any of these points from 1. to 3. (Play/Noise/Guns)
Replace if necessary complete AC compressor with new magnetic coupling at a mileage above 200,000 km or at 100,000 km in active operation for refrigerated/freezer transports.
