This gearmotor is a miniature (26mm x 12mm x 10mm), high-quality, high-power motor with 50:1 metal gearbox, similar to Sanyo’s popular 12 mm gearmotors. These units have a 9mm long, D-shaped output shaft.


Key specs at 6 V: 625 RPM and 100 mA free-run, 1.0 kg-cm and 1600 mA stall.


This motor has a long (0.365" or 9.27 mm), D-shaped metal output shaft, and the brass faceplate has two mounting holes threaded for M1.6 screws (1.6 mm diameter, 0.35 mm thread pitch). It weighs approximately 0.35 oz (10 g).

Motor Accessories Wheels and Hubs: The micro metal gearmotor's output shaft matches the Pololu wheel 32—7mm, Pololu wheel 42—19mm, and Solarbotics RW2 rubber wheel. You can also use the Pololu universal mounting hub to mount custom wheels and mechanism to the micro metal gearmotor's output shaft.

Mounting Brackets Our mounting bracket (also available in white) and extended mounting bracket are specifically designed to securely mount the gearmotor while enclosing the exposed gears. We recommend the extended mounting bracket for wheels with recessed hubs, such as the Pololu wheel 42—19mm.
