Micro Metal Gearmotor

This is a miniature brushed DC micrometal motor with a metal gearbox available in a range of gearing ratios depending on use. Also known as an 'N20 motor'.

All of the micro metal gear motors have the same physical dimensions, so one version can be easily swapped for another if your design requirements change. they work perfectly with Pololu 42x19 wheels or track kits!

If you need a motor driver to go with them, check out our motor driver section.
