Micro Metal Gearmotors

With a cross section measuring only 10×12 mm (0.39″×0.47″), these small 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. Some versions are also available with an optional extended motor shaft.

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.
