RE: [CAD_CAM_EDM_DRO] Slo Syn 3 wire motor

Hi Paul,

Building a 120v driver will be much harder (and not as safe) as a typical
36V driver. Not to mention fooling around with re-wiring the SYNCHRONOUS
motor. Not a very good candidate and not recommended in my opinion.

Although not very fast or powerful, a unipolar driver is easy to make from
four Darlington power transistors.

Check E-BAY? Perhaps someone could mail you one?
