Purpose
The magnetic clutch transmits the rotation force from the engine to the shaft in the A/C compressor.
Function
The magnetic clutch engages or disengages the magnetic clutch and the A/C turns on or off by switching the power transmission from the engine.
Construction
The magnetic clutch is installed to the A/C compressor.
The magnetic clutch consists of the following parts:
Pressure plate
A/C compressor pulley
Stator
Snap ring
Shim
Operation
Magnetic clutch disengagement
1. If there is no energization in the magnetic clutch stator from the A/C relay, the pressure plate cannot be engaged with the A/C compressor pulley because the magnetic clutch stator does not operate.
2. The rotation force from the drive belt is only transmitted to the A/C compressor pulley and the pulley spins.
Magnetic clutch engagement
1. If there is energization in the magnetic clutch stator from the A/C relay, the magnetic clutch stator operates and the pressure plate is engaged with the A/C compressor pulley.
2. The rotation force from the drive belt is transmitted to the compressor shaft through the pressure plate from the A/C compressor pulley.
Fail-safe
Function not equipped.
PCM
Purpose/Function
High-level driveability and lower fuel consumption have been realized by
controlling the appropriate engine conditions (fuel injection/ignition timing)
according to operation conditions.
Controls each output part based on the signal from each input part.
