What happens when the air conditioner magnetic clutch is off?
As a result, the stator pulls the center piece with strong magnetic force so the compressor turns together with the pulley. When the magnetic clutch is off, current doesn’t pass through the stator, which causes the center piece not to be pulled and only the pulley turns idle.
Who are the manufacturers of air applied clutches?
Air-applied clutches manufactured by Eaton Airflex, WPT Power, Nexen, Goizper and many more leading brands. ICP offers all types of pneumatic clutches. Pneumatic drum clutches, tooth clutches, power take-off clutches, low inertia clutches, high torque clutches, and disc clutches available directly from stock.
Where is the stator on an air conditioner clutch?
The center piece is installed together with the compressor shaft and the stator is held on the front housing of the compressor. When the magnetic clutch turns on, current passes through the stator coil, which makes the stator a strong electromagnet.
How is torque transmitted in a magnetic clutch?
There is no mechanical contact between the rotating members of the magnetic drive. Thus, there is no wear. Torque is transmitted between the two rotating units by an electromagnetic reac tion created by an energized coil winding.
When to set a / C CLUTCH relay control circuit code p0645?
When the Powertrain Control Module (PCM) or one of the other supporting control modules has detected improper signals within the A/C clutch relay control electrical circuit, code P0645 will be set. Based on the vehicle and the specific malfunction this code may be set as many as eight times before the check engine light is illuminated.
What does the OBD code p0645 stand for?
Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration. The P0645 OBD-II trouble code is associated with the air conditioning (A/C) clutch relay control circuit.
When does the PCM set the code p0645?
Code P0645 is set by the PCM when it detects a general malfunction in the air conditioning relay control circuit.
Why do I have a p0645 code on my air conditioner?
The most common mistake when diagnosing the P0645 code is to misdiagnose the symptoms and codes. This is because of the complexity involved. Replacing air conditioning components when damaged wiring, ground straps or another component are the problem is very common with this code.
