The GM10 is a very small brushed DC motor and gearbox combination. At 5 volts, the motor draws 27 mA, and the 81:1 gear ratio delivers 370 RPM. This gearmotor provides 3.6 oz-in of torque with a stall current of 184 mA. All of this is in a tiny package with a weight of only 5 grams! This motor has 12" stranded wire leads.

This motor does not have continuous rotation by default, but you can easily remove the centering spring that limits motion to approximately 60 degrees in each direction. Removing the included arm exposes a 0.190" round shaft that is 0.125" long; the last 0.050" of the shaft is a square with 0.140" sides. The GM10 1" wheels are designed specifically for use with this motor once it has been modified for continuous rotation.

If you’ve been looking for the right motor and gearbox for your next micro-sized robot project, this motor is for you! Pololu also carry a variety of larger gearmotors, which are listed on Pololu's gearbox page.

Note: The GM10 81:1 geared pager motor does not come with mounting hardware, instructions, or packaging.
