A 6V brushed DC motor with a 20:1 metal gearbox and an integrated quadrature encoder. The encoder provides 11 counts per revolution of the motor shaft, corresponding to 224.4 counts per revolution of the gearbox output — giving precise speed and position feedback for closed-loop motor control.
The D-shaped output shaft is 4 mm diameter × 8 mm long. The motor starts rotating from as low as 1V, with a rated voltage of 6V.

Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- 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.
