A 1000:1 micro metal gearmotor from Pololu's popular N20-size range, featuring a high-power (HP) 6V brushed DC motor with precious metal brushes. With the highest gear ratio available in this series, it delivers extremely low output speeds and very high torque relative to its tiny size.
At 6V with no load, the output shaft turns at approximately 31 RPM, and speeds as low as ~2.5 RPM can be achieved at 0.5V. The 1000:1 version is slightly longer than other ratios in the range due to the additional gear stage.
Key Features
- 1000:1 Gear Ratio – Extremely low speed with very high torque output
- High-Power (HP) Motor – 1.6A stall current for maximum performance
- Precious Metal Brushes – Low electrical noise; terminal width 1.5mm, spacing 7mm
- N20 Form Factor – Compatible with a wide range of wheels, brackets, and encoders
- All-Metal Gearbox – Durable spur gears for sustained operation
Specifications
- Gear Ratio – 1000:1 (exact: ~986.41:1)
- Nominal Voltage – 6V
- No-Load Speed – 31 RPM @ 6V
- No-Load Current – 0.07A
- Stall Current – 1.6A
- Stall Torque – 12 kg·cm (170 oz·in)
- Motor Type – Brushed DC, high-power (HP), precious metal brushes
- Output Shaft – 3mm diameter, D-shaped
Ideal For
- Applications requiring very slow, controlled rotation
- High-torque mechanisms in small form factors
- Robotics and automation projects
- Pan/tilt mechanisms and slow actuators

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.
