How Motor Run Capacitors Work
Motor run capacitors play a critical role in the operation of single-phase AC motors. The capacitor creates a phase shift between the main winding and auxiliary winding of the motor, generating a rotating magnetic field essential for motor startup and continuous operation. This phase difference enables the motor to start efficiently and maintain smooth, consistent performance.
During operation, the 3.5µF motor run capacitor remains connected in the circuit, continuously improving motor torque, reducing vibration and noise, maintaining stable rotational speed, and increasing overall system efficiency. This results in quieter fan operation, better energy efficiency, and extended motor lifespan.
