Simplified Guide: Wiring a Baldor Single Phase Motor with Capacitor
Capacitor: In some single phase motors, a capacitor is used to provide an additional phase shift to the motor windings. This helps to improve the starting torque and efficiency of the motor. The capacitor is connected in series with the start winding of the motor and is controlled by a centrifugal switch, which disconnects the capacitor once the motor reaches a certain speed.
