Re: [CAD_CAM_EDM_DRO] Re: stepper wiring

Hi Guys:

I use the same motors as steppers. They work great and give 2000P/S out.
They are VERY stong and work great as bi-polar steppers at 60VDC at 2Amps.
You just have to remove the back cover, ther is a printed circuit board with
all the coils connected to it. Cut all the traces and solder two wires to
each set of 4 coils. (eight coils in all).
Thats it, then they work as great,cheap and powerfull steppers. I run them
at up to 10inches per second through hardwood.
