4.7.6 Clutch
●
The electromagnetic clutch is used to
transmit moment of torsion. When the en-
gine is operating, the compressor may not
be working. The clutch controls the opera-
tion of the compressor only when the air
conditioner is under refrigerating mode.
●
Operating principle
When the A/C switch is turned on, the
clutch coil with an electromagnet gener-
ates a magnetic
fi
eld and attracts the metal
piece. The stator and rotor of the clutch are
engaged and drives the main shaft of the
compressor into rotation.
