Re: Calculating Linear Force from Motor Torque?

So your reasoning is valid thus far, but what is the consequence of using stall Torque? What is the current draw? How fast does it move?
Well, it wouldn't move

By what means can I calculate a given torque at a given speed, then?

The motor is 152 rpm.

If I wanted, say, 80 rpm, could I find the percentage of total RPM (80/152) and multiply that by the stall torque to find corresponding torque at the given speed?

I'm assuming speed and torque change by the same factor, proportionally to the drop in voltage.
