How the 3.5µF Capacitor Works
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. This continuous operation ensures your fan or motor runs at peak efficiency throughout its service life.
