The Solarbotics GM8 - Gear Motor is much like the but runs at nearly twice the speed. This 143:1 gear motor 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 fit perfectly with GMPW and GMW plastic wheels.
GM8 - 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.
