What Is a Start Capacitor?
Start capacitors are connected in series with the start winding of a single-phase motor and remain in the circuit only during the motor’s startup phase. By temporarily increasing the motor’s starting torque, they allow the motor to overcome initial inertia and reach operating speed efficiently. Once the motor reaches sufficient speed, the start capacitor is switched out of the circuit, protecting it from overheating.
