It's hard to say but I "think" the 15hp motor worked the best. I've been running and trying different things for a 1 1/2 years so my memory is a bit clouded on exactly how it worked or didn't work. I do know at one time my workaround was to ramp up the spindle from 2k to 6k and it ran like that and that was on one of the 10hp motors.
Do you think adding a line reactor after the rotary phase converter would help in any way? I can get a 3 phase 20hp one for $150 so it is cheap enough to try if anyone thinks it might help in any way. http://www.automationdirect.com/adc/Shopping/Catalog/Drives/GS2_%28115_-z-_230_-z-_460_-z-_575_VAC_V-z-Hz_Control%29/AC_Line_Reactors/LR-2020 Taking the reactor out of the VMC sure made it worse... and the scope trace looked horrible jagged.
