Hi again, Ok, so 100W is on the low side, what power levels are you guys running ? I might have some 300 W ones lying around somewhere also. I looked at the power level of some steppers used for cnc conversion and NEMA 23 bipolars seemed to be around 100 W The motors are two phase AC servos, thu

I have heard you guys speak highly of servos, and I haven't got a clue if you are running DC or AC servo motors ? The reason is that I have some AC servo motors around 100W or so, would they be good candidates for a EMC machine ? Better than steppers ? I haven't considered them since the cont
