The GM8 is similar to the GM2 gear motor but runs at nearly
twice the speed. This 143:1 gear motor spins at 40RPM on 3V
of 400mA at stall generating 44.4 in*oz torque
(free running @ 50mA).
With a 7mm double-flat output shaft a built-in clutch and
built-in mounting screw holes.
You must avoid using the green double flat output shaft
it's not meant to take rotational load.
These units are overall 53.8mm x 47.8mm x 22.9mm thick
