A Pololu micro metal gearmotor with a 5:1 gear ratio and low-power (LP) 6V motor. The LP motor variant uses precious metal brushes and draws the least current of the micro metal gearmotor family, making it well-suited for battery-powered projects where efficiency matters more than peak torque.
At the 5:1 ratio, this is the fastest variant in the LP range, delivering 2,500 RPM no-load speed. The standard Pololu micro metal gearmotor form factor (sometimes called N20) is compatible with a wide range of Pololu wheels, mounting brackets, and encoders.

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.
