Why is a Capacitor Needed for a Single-Phase Motor?
Without a capacitor, the motor will lack the necessary phase shift to create a rotating magnetic field. As a result, the motor will either not start at all or will start slowly and with reduced torque. This can cause the motor to overheat and eventually fail.
