The Solarbotics GM9 Gear Motor is much like the but runs at nearly twice the speed. This gear 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 fit perfectly with GMPW and GMW plastic wheels.
GM9 - Gear Motors are compatible with the Solarbotics Wheel Watcher Rotation Encoder. Use it if you need to control a robot for dead reckoning, tracking odometry (distance traveled), stalled motor, or closing the feedback loop for position/velocity/acceleration.
