Re: [CAD_CAM_EDM_DRO] Re: stepper wiring

I do not think these slo-syn motors are typical 6 wire motors with the
center taps, but I could be wrong. I think these motors were origonally
designed to be AC synchronous motors, with a capacitor. Maybe you are
talking about a different motor, but it sounds like some I used. If no one
else can help you figure the wiring out, ask again, and I'll try to dig up
the schematic that Dan Hudgins gave me to hook up mine about 6 years ago.
