Does anyone happen to know specs on the pinion gear attached to the Keyang motor? Based on the outside diameter, I was able to figure out that it appears to be a 12 DP gear. If someone could verify this for me that would be great. But now that leaves the question of what pressure angle the gear is... does anyone know?
Also, as far as I can tell, this is very similar, if not equal to the Keyang model PWM-60B.

The torque curve data also matches up with what FIRST has published.
So pretty much, does anyone know the pressure angle of this pinion gear? If we knew then everyone could use it without the included plastic coupler and without making a custom coupler. Thanks.
