Trying to understand rotary phase converters, I have a 7.5 HP Clausing lathe knock off. It runs off of three phase ,do I understand it correctly that I will need a converter greater than 15 HP to correctly run this off of 220v single phase? My "shop" is in a storage area with no electricity... I have successfully run my 2HP 220v single phase mill with the generator. I understand 7.5 HP is a big jump from 2 HP... My only options are: a bigger generator... a bigger 3 phase generator....... Any suggestions??
