WebHow capacitor is used in motor? Some single-phase AC electric motors require a "run capacitor" to energize the second-phase winding (auxiliary coil) to create a rotating magnetic field while the motor is running. Start capacitors briefly increase motor starting torque and allow a motor to be cycled on and off rapidly. WebTo do so, we add a capacitor in series with the staring wind. The following happens when we switch on the circuit due to the inductors and capacitors in this circuit: Current leads by 45° from voltage (or voltage lags 45 degree behind the current) in …
