The Pololu 313:1 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 brushed DC motor integrated with a 312.5:1 metal spur gearbox, providing a robust solution for precise motion control. The gearmotor's cylindrical design has a diameter of 20 mm, and it includes a D-shaped output shaft with a 4 mm diameter that extends 18 mm from the gearbox face plate.

Operating at 6 volts, the gearmotor achieves a rotational speed of 45 RPM with no load, drawing a current of 170 mA. Under stall conditions, it can deliver a torque of 220 oz-in (16 kg-cm) while consuming 2.9 A of current. This makes it suitable for applications that demand significant torque output within a compact mechanical footprint.

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