I ran across some stepper motors the other day that were $9.95 each. I can't remember the exact details, but they were about 3V, 3A, 1.8deg/step, NEMA 23. Looked to be single stack. These had 4-wires, not 6. I'm curious about drivers for 4-wire steppers as opposed to 6-wire steppers. I see a lot of driver "kits" that will handle 5, 6, and 8-wire motors, but I don't see much on 4-wire motors. What's up with this?
Thanks,
Curtis
