Micro Metal Gearmotor (Extended back shaft) – 20:1

This gearmotor is a miniature brushed DC motor with a metal gearbox available in a range of gearing ratios depending on use.

Ratio Speed @ 6V Free-run current @ 6V Stall torque @ 6V (minimum) Stall current @ 6V
11:1 1800±10% rpm 80mA (160mA max) 0.12kg. cm 650mA Datasheet
20:1 1050±10% rpm 90mA (180mA max) 0.26kg. cm 850mA Datasheet
50:1 420±10% rpm 90mA max 0.4kg. cm 920mA Datasheet
110:1 190±10% rpm 39mA (78mA max) 0.9kg. cm 600mA Datasheet
298:1 75±10% rpm 100mA max 2.1kg. cm 920mA Datasheet
1006:1 14.2±10% rpm 56mA max 2.9kg. cm 380mA Datasheet
  • All of the micro metal gearmotors, except the 1006:1 variant, have the same physical dimensions, so one version can be easily swapped for another if your design requirements change.
  • Long (12mm), 3 mm-diameter D-shaped metal output shaft.
  • 4.5mm long, 1mm diameter back shaft, great for optical encoders!

Why not try it with Yukon?

Looking for a controller for your project? Yukon is a high-power modular robotics and engineering platform, built around RP2040 and designed to drive the most ambitious robots, props and devices.

Yukon is a standalone controller that can be equipped with up to six interchangeable modules capable of driving high-powered hardware - this is made possible by the unique pin capabilities of Raspberry Pi's multitalented RP2040 chip. This flexibility means you can drive many unique combinations of motors, servos, steppers, speakers, LED strips and more, all from a single Yukon host!
