I need to construct a rotary phase converter for a Topturn cnc lathe that I purchased. It has a 7 1/2 hp spindle motor and uses 3 phase ac servo drives with a Fagor 800T control. The line voltage in my area is already high (243 volts), and this lathe needs 220 volts +/- 10%. This would be an expensive machine to repair if I had any overvoltage problems. I ran it momentarily on a 15 hp rotary converter and had voltages of 248-248-254 - I would like to make a dedicated 20 hp phase converter for this machine but am wondering what would be the best way to lower the voltages. thanks, Terry
