These tiny brushed DC gearmotors are intended for use at 6 V, though 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 (rotation can start at voltages as low as 0.5 V). Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor. The Micro Metal Gear Motor HP w/ 50:1 gear ratio and Micro Metal Gear Motor HP w/ 75:1 gear ratio are also available.
The gearbox has a long (0.365" or 9.27 mm), 3 mm-diameter 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). Versions with the extended motor shaft have a 1mm diameter round shaft that protrudes 4.5 mm from the rear of the motor, between the two motor terminals; this is not pictured in the above dimension diagram.
The Pololu Zumo chassis is a small, tracked robot platform that is less than 10 cm on each side, allowing it to qualify for Mini Sumo competitions.
These plastic mounting brackets allow you to simply and securely mount the micro metal gearmotors that we offer.
This is our IG42 DB Heavy Duty Vectoring All-Terrain Robot Chassis. It is designed for our IG42 motors with 6 inch mecanum wheels.
This is a fully assembled, second-generation LT2 robot platform. We use the same chassis in our tactical LT2. It's similar to our HD2 treaded robot, but it's lighter.
