Bipolar motor controller.

[Jolijar]

I found some of these at the local surplus store (American science & surplus) for $0.95 each. They are Bi-polar (4 wire) and have a resolution of 20 steps. It is a Molon LMO-6360 #37397-000

I would like to use these in my cnc table I am building. Does anyone have a good source for a simple 3 axis bipolar motor controller that I can build or buy.

do you know torque of this 20step/rot motor?
probably torque too small, and resolution is poor

as a start point...
you could search 200step/rot motor, size 57mm, torque about 0.5...2Nm (~71...286 oz-in)

simple stepper drivers with IC like: a3977. ta8435...
google can show you projects
