The Micro Metal Gearmotor 50:1 is a compact, high-quality DC motor with an integrated metal gearbox, ideal for small robotics and motorised projects. With a 50:1 gear ratio, it delivers a good balance of speed (260 RPM) and torque at 6V.
The motor features a long D-shaped metal output shaft (9.27 mm) compatible with Pololu 42×19 mm and 32×7 mm wheels. The brass faceplate includes two M1.6 threaded mounting holes, and Pololu mounting brackets are available separately for secure installation while enclosing the exposed gears.

Jargon buster
Plain-language definitions for the technical terms used above.
- kg·cm
- A torque unit often used for hobby servos, meaning how many kilograms of force the servo can hold at a 1 cm arm length. A higher kg·cm rating means the servo can move or hold heavier loads, but power supply current needs may also increase.
- Stall torque
- The maximum twisting force a servo can produce when its output is held still and cannot move. It helps you judge whether the servo is strong enough for a robot joint, steering linkage, or other load.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
