  • Motor start and run capacitor - Electrical Engineering Centre

    Mar 21, 2011 · The motor working voltage ( Vc ) is about 1,5-2 times the mains supply and decrease with the increase of the load.With capacitive reactive power of about 75% of the nominal power of the motor, the comparison of power is slightly lower than that of a three-phase motor of equal size. For running capacitor are rated in a range of 3-70 microfarad.
