Tips: Working principle of air conditioner capacitor

The single-phase compressor of an air conditioner needs a capacitor to split the phase in the process of starting. The capacitor is easy to overload when it runs under a higher voltage of 220V in the household. Whether the capacitor is good or bad directly affects the start of the compressor, so the air conditioner can not start normally should first check the capacitor, capacitor damage is also often seen.

A capacitor induction motor has two windings, respectively, for a start winding and run winding. In the start winding in series with a large-capacity capacitor. When the running winding and the starting winding pass through a single-phase alternating current, the starting winding makes the starting winding current 90 degrees ahead of the running winding in time due to the capacitor, and the motor generates induction current when the magnetic field rotates, and the current interacts with the rotating magnetic field to make the motor rotate. The above is the explanation of the principle of the air conditioner capacitors.
