About the Product

 

Pololu 154:1 Metal Gearmotor 20Dx44L mm is a small brushed DC gearmotor that can deliver a lot of power for its size. This version has a 154:1 metal gearbox with a 7mm (0.276") long, 4 mm-diameter D-shaped output shaft.

Pololu 154:1 Metal Gearmotor 20Dx44L mm is intended for use at 6 V. In general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range. Higher voltages could start negatively affecting the life of the motor, and lower voltages might not be practical.
