The Pololu 125:1 Metal Gearmotor 20Dx44L mm 6V is a compact yet powerful brushed DC gearmotor designed for applications requiring high torque in a small form factor. This model features a 6V motor integrated with a 125:1 metal spur gearbox, providing a robust solution for various mechanical tasks. The gearmotor’s cylindrical design has a diameter of 20 mm, and it includes a D-shaped output shaft that measures 4 mm in diameter and extends 18 mm from the gearbox’s face plate.

Operating at 6 volts, this gearmotor achieves a no-load speed of 110 RPM while drawing a current of 170 mA. It is capable of delivering a stall torque of 87 oz-in (6.3 kg-cm) with a stall current of 2.9 A, making it suitable for demanding applications. However, users should be aware of the gearbox’s torque limit, which is set at 70 oz-in (5 kg-cm), to ensure optimal performance and longevity.

Note: The gearbox torque limit is 70 oz-in (5 kg-cm); exceeding this limit may result in damage to the gearmotor.
