Micro Metal Geared Motors

These micro geared motors from Pololu and Solarbotics have a cross section measuring only 10×12 mm.

The Pololu brushed DC gearmotors are available in a wide range of gear ratios from 5:1 up to 1000:1 and offer a choice between three different motors: high-power (HP), medium-power (MP), and standard. With the exception of the 1000:1 gear ratio versions, all of the micro metal gearmotors have the same physical dimensions, so one version can be easily swapped for another if your design requirements change.

The Solarbotics range, remain a popular choice with builders.

Note: The 1000:1 gearmotors can generate enough torque to damage themselves. The stall torque values given for those two motors are theoretical, and we strongly recommend you avoid stalling them.
