100:1 Micro Metal Gearmotor
This gearmotor is a miniature (0.94" x 0.39" x 0.47"), high-quality, low-current motor with 100:1 metal gearbox, similar to Sanyo's popular 12 mm gearmotors. These units have a 0.365"-long, D-shaped output shaft.
Key specs at 6 V: 120 RPM and 40 mA free-run, 10 oz-in (0.7 kg-cm) and 0.36 A stall.
These tiny, high-quality motors are 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 to 9 V range. Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor. All of the micro metal gearmotors have the same physical dimensions, but they come in a wide range of gear ratios from 5:1 up to 298:1 and let you choose between two different motors: high-power (HP) and standard. This means you choose the version that has the ideal blend of speed, torque, and current-draw for your particular application. Please see the table at the bottom of this page for detailed specifications, or look at micro metal gearmotor comparison table.
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).
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.
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.
