i see some motors rating Minimum
Holding Torque (oz-in) then i see
torque (lb. In)

so is dc servo motor rated 3000 rpm at 3 (lb. In)

strong than a 264.0 (oz-in) stepper motor

264 oz-in = 16.5 lb-in
3 lb-in = 48 oz-in
You will have to look at the torque/speed curve for the full picture.

How does I convert from oz-in to lb-in if I can ask?
These is two different unit, in addiction to Nm?
(I have already learned that 1 oz-in = 0.00706 Nm)

Thanks a lot - both of you!
The second solution was much better than the first, as I do not use Windows. :)
