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.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
