Re: Approx max rpm for this stepper motor?

Jon,

You should be able break things and the some with that reduction. The
thing to remember is what matters is power and power is speed times
torque. You get 80 times less speed but 80 times more torque
(assuming 100% efficiency in your reducer). Multiply the two and you
still get the same power.

Specifically, 80 X 156 oz-in equals 65 ft-lbs of torque, 3100 full-
steps per sec. divided by 80 equals 11.625 RPM. Slow but strong!
