Calculate the rated required capacitance value for the single-phase, 220V, 1 HP, 50Hz, 80% of the motor. 1 HP = 746 Watts. Use our capacitance calculation formula. C (µF) = 746 x 80 x 1000 / (220 x 220 x 50) = 24.66 µF. Hence 1 HP Motor required 24.66 µF capacitance to start the motor smoothly. But in the market, you can get 25 µF.
