## Description

## Gearmotor Dimensions:

This brushed DC gearmotor has a long (0.365" or 9.27 mm), 3 mm-diameter D-shaped metal output shaft that matches Pololu's assortment of [Pololu wheels](https://core-electronics.com.au/#) and the [Solarbotics RW2 rubber wheel](https://core-electronics.com.au/solarbotics-rw2-wheel-external-set-screw.html). Alternatively, Pololu's [3mm universal mounting hub](https://core-electronics.com.au/pololu-universal-aluminum-mounting-hub-for-3mm-shaft-2-56-holes-2-pack.html) can be used to mount custom wheels and mechanisms to the gearmotor’s output shaft.

These motors are intended for use at 6 V. In general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range. Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.
