Re: Motors

Don't forget that the Drive Electronics is different for Unipolar
than Bipolar, typically Unipolar Drive is simpler, less expensive
where Bipolar Drive abit more complex and expensive is usually better
performing. Or... You get what you pay for.
So try to specify your drive electronics and motor types together.

Many tutorials available on the web.
Try... http://www.super-tech.com/root/motors.htm
It address directly Uni/Bipolar differences.

Personally, if your talking about a couple of ampers or more per
winding, it is difficult to beat the Price and Performance of a GECKO
drive. I feel Unipolar is attractive in the smaller,low power
applications.
