Pololu Metal Gearmotors

Pololu metal gearmotors arranged by size from left to right: micro, 100:1 and 24:1 mini, 35:1 mini, and 25:1 20Dx44L mm.


We offer a wide, and growing, selection of high-quality metal gearmotors that will let you choose the optimal torque and speed for your application. In particular, our micro metal gearmotors come in nine different gear ratios and with two different motors: a high-power (HP) version and a low-current version. The following link will take you to a parametric comparison table that can help you find metal gearmotor that is just right for your project:
