The single phase motors require capacitors for constant efficiency. A capacitor is a device that increases the efficiency of a single-phase motor. A capacitor provides the required phase difference; thus, the motor self-start and runs the winding current. A capacitor increases the power factor because a single winding cannot produce RMF itself.
A capacitor in series is connected to the auxiliary winding to provide a 90-degree phase difference to produce a rotating magnetic field. A single phase motor with a capacitor generates high starting torque. The auxiliary and running winding voltage provides 90-degree displacement, which upgrades the running condition of the motor.
