Working Principle
A motor run capacitor creates a phase shift between the motor’s main and auxiliary windings. This phase difference generates a rotating magnetic field that helps the motor start smoothly and continue running efficiently.
The 3.5µF capacitor remains connected while the motor is operating, improving torque, maintaining stable speed, reducing vibration, and enhancing overall motor performance.
