Mark: The MO-91 is a "Size 34, single-stack" motor. For what I recall you
want to do, you would surely need at least an MO-92 FD08, which is a 3-volt,
4-amp motor. Same "face", but a little longer than yor MO-91. But if
surplus is an unavoidable "MUST", then I don't want to waste your time!

I built a couple of small woodworking lathes using said MO-92 unipolar
motors, and then in '99, two more using the new "bipolar chopper-drive"
motors and Superior Electric chopper-driver with built-in power-supply.
Expensive, but that setup works SO much more perfectly than the old
"unipolar" system, I'd never go back! Looking in Superior Electric's
catalog, there are even some of their new KML-06n motors (Size 23) with more
torque than your -091!

I will TRY to put a link for Superior Electric for you, here. Look at their
web-site. Educational, at least!
