I just built my 1st rotary phase converter 5 horsepower idler motor, load will be leblond lathe 3hp. capacitors I can get to balance at 242 t1t3, 241 t2t3, 241t1t2 voltage but once motor is running they drop down to 230 t1t3 and 231 t2t3 witch make lathe struggle at high speed 1800rpm is that OK or should I up capacitor higher at idle like 251v and then when I run under load it drops down around 240v . I'm afraid of damaging idler motor at 250 V when it is wired for low voltage.
