WebPermanent Split Capacitor (PSC) Motor In a capacitor start method, a capacitor has to be disconnected after the motor reaches to a specific speed of motor. But in this method, a run-type capacitor is placed in series with the start winding or auxiliary winding. WebMotor start capacitor is an electrolytic capacitor connected in series with auxiliary winding, which is switched off once motor picks up speed to near 70 percent of full rated speed. Value if the capacitor normally can vary from 30-40 mfd to 200-250 mfd for 230 V motors, and working voltage is 230 V AC.
