Good work. I used a Bardac 1600i to control the spindle motor on my lathe. Originally the motor was 140vdc. I think the Bardac with a 120v input only puts out a 90 vdc however it gives me the rpm I request. If I moved up to a 220 input I could get up to a 180vdc output (output is adjustable). It will allow dual vlotage input. Anyway nice work.
