Overview

This brushed DC gearmotor is very compact and weighs only 19.5 grams — perfect for building a quick, miniature robot. The recommended operating voltage range for this motor is 3 to 6 V, though the gearmotor can start rotating at voltages as low as 0.6 V. At 4.5 V, the motor has a free-run current of 80 mA and a stall current of 800 mA; this relatively low current draw makes this a great match for our qik 2s9v1 dual serial motor controller and programmable Orangutan robot controllers. The stall current, torque, and rotation speed will approximately scale linearly with the motor voltage. The gearbox is protected by a built-in safety clutch that will typically slip before gear teeth can shear.

This gearmotor features a 3 mm D-shaped output shaft that matches those on many of our micro metal gearmotors and works with the Pololu wheels and 3mm universal aluminum mounting hub.

Gearmotor Versions

This gearmotor is available with two different output shaft orientations—offset from but parallel to the motor shaft or perpendicular to the motor shaft—and in two gear ratios—120:1 (for higher speed) or 180:1 (for higher torque).
