This 143:1 gear motor is much like the GM3 gear motor but runs at nearly twice the speed. Great for robots needing speed over torque!

With a 7mm double-flat output shaft (there is no output on the other side), 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 70.5mm x 27mm x 23mm thick
