Has anyone used a Prop to drive a variable reluctance stepper with three phases. I just finished my own prop version and was wondering if anyone else has fiddle with these. The one I encountered had windings like a unipolar stepper but with only three phases. So one main power wire and three coil wires A, B, and C. It had a feedback pot so I used that for my position holding. Seem to draw a lot of cuurent if one or two phase were left on. I would only send a step command if the shaft was nudged off null.
