Re: 2012 KoP motor part numbers

3.52 lbf-ft * 1.356 N-m/lbf-ft = 4.77 N-m
42 rpm * 0.10472 (rad/s)/rpm = 4.4 rad/s

4.77 * 4.4 = 21-ish.

Your math checks, so I'd guess there's a problem with the specs somewhere. Probably the listed max power. The input power at half torque is about 73W. So at max power it's either 30% efficient, or 178% efficient. I know which side I'm putting my dollar on....
