GM9 (143:1 90 Degree Shaft)


Vendor's Description: 


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!

Another available-from-Solarbotics-only motor is the GM9 143:1 gear motor. The GM9 is much like the GM3 gear motor but runs at nearly twice the speed. This motor goes 66RPM at 5V, drawing 670mA at stall generating 43 in*oz torque (free running at 73.2mA).

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 (2.78") x 27mm (1.06") x 23mm (0.906") thick.
