Mazda CX-5 Service & Repair Manual: Magnet Clutch [Manual Air Conditioner]

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

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.
