Re: Need help! Balance voltage rotary converter motor 7.5 hp
What generaldisarray said, swap the motor leads, at the A and C connection points and see what that does. And check it under load, I used 3 stove top elements as a resistive load for initial setup. Then did the final tuning when running the lathe. I had to play around with my connections a bit to get it to balance. Unloaded T1-T3 (A-C) is about 256, but loaded it's 240,240,239 (when I checked it today). I also used the FitchW pdf as the basis for my design.
EDIT: Are you sure you have the motor properly wired for 230V? T1 1-7, T2 2-8, T3 3-9, and 4,5,6 connected together.
