Re: [CAD_CAM_EDM_DRO] Re: stepper wiring

Marris,

Ya know, I think you are correct. Now, how did I hook up those AC
synchronous motors and drive them as biplar driven steppers? Maybe they
had three wires? I know they were AC because I used some as AC motors.
You could reverse them easily with a switch controlling the cap/motor hook
up.
