Re: Slo Syn 3 wire motor

Hello,

Get ahold of DanCAD/CAM 3d, by Dan hudgins. He shjows how to use
these three wire syntchrounous motors as steppers, and his full set
of documents ahs been used by people all over thr world to make
things move; since the circuits are simple, the instructions are
clear--but wordy--and th eparts are available.

He specifically details using the motor type you have. Note that
this motor will be relatively slow, with 300RPM being typical with
older style drive techniques.

Hope this helps,

Ballendo

P.S. You don't need a 120v driver.
