From what I ve read the circuit provides in this way 330 V , would this be enough ?

Another method is with the classic capacitor method used for 3 phase motors in shops:

Can someone with better electronic knowledge step in please and say if we can do this capacitor method ?



I think the circuit in this video is the salme with this link:
