Re: 2012 KoP motor part numbers
I think your math is correct.
Peak mechanical power (at half of free speed and half of stall torque) is about 21W.
Electrical power would be about 70W under those conditions.
I don't have access to my team's motors right now, but after the Monday meeting I will take them to the lab, and try report dynamometer test results on Tuesday or Wednesday.

Edit: It appears that this gearmotor is aimed at replacing the old-favorite Globe transfer case gearmotor, which had more than twice the stall torque and about the same free-speed. That motor could develop about 80W peak mechanical power, if I recall correctly.
