This 143:1 gear motor is much like the GM2 gear motor but runs at nearly twice the speed. Great for robots needing speed over torque!

The GM8 spins at 70RPM at 5V, drawing 670mA at stall generating 43 in*oz torque (free running at 57.6mA).

With a 7mm double-flat output shaft (avoid using the green double flat output - it's not meant to take rotational load), and a built-in clutch and built-in mounting screw holes, you can see why we like these motors!

These units have an overall size of 55mm (2.17") x 48mm (1.89") x 23mm (0.906") thick and weighs in at 32g or 1.13oz.

NOTE: These motors have shorter output shafts for this reason we do not include the small plastic mounting wheel as it tends not to fit as well on the shorter output shaft.
