The Pololu 391:1 Metal Gearmotor 20Dx46L 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 390.6:1 metal spur gearbox, providing a robust solution for precise motion control. The cylindrical design has a diameter of 20 mm, and the D-shaped output shaft measures 4 mm in diameter, extending 18 mm from the gearbox face plate.
Operating at 6 volts, the gearmotor achieves a rotational speed of 36 RPM with no load, drawing a current of 170 mA. Under stall conditions, it can deliver a torque of 260 oz-in (19 kg-cm) while consuming 2.9 A. This makes it suitable for applications that demand significant torque output.
Note: The gearbox torque limit is 70 oz-in (5 kg-cm); exceeding this limit may result in damage to the gearmotor.
