 this is a cct to start a three phase motor with a single phase supply and using a capacitor... to charge the cap with 220V AC at 50 HZ, which is my supply, I have done the following calculations... C = 1 / 2 * PI * F * XC VC = 220 V XC = 220 / 2 * PI * F C = 4.55 mF is all this correct? I just want to know how to calculate the capacitor value actually...

anyone have a wiring diagram? saw somewhere else that 1KW = 65uF... how does this work for every KW, does it increase by 65uF for every KW? can someone just explain in simple words not high electric words like VFD and all that I don't understand that... I am still a student just need to know how to do it whether its efficient aint the worry at all... and also read something about if you have 15HP motor you will only have about 5HP when using this method...
