This compact bracket enables convenient mounting of popular Pololu miniature metal gearmotors. The white plastic bracket encloses the otherwise exposed gears, and the mounting tabs capture the nuts for easy installation. This version has mounting tabs that allow for use with the Pololu Wheel 42×19 mm and encoder. The brackets are sold in pairs, and each bracket comes with two #2 screws and two nuts.
These plastic mounting brackets allow you to easily and securely mount the ubiquitous 10 mm x 12 mm x 26 mm metal gearhead motors first popularized by Sanyo’s 12GN series (e.g. NA1S…NA3S), such as the Pololu miniature metal gearmotors and the Solarbotics mini metal gear motors.
This extended version of the bracket is designed to allow a portion of the motor to fit within the hub of a larger wheel, such as our Pololu Wheel 42×19 mm. We also offer a quadrature encoder that works with this bracket and the 42×19mm wheel to provide feedback about wheel rotation direction and speed. The encoder can be purchased as an individual unit or as part of an encoder set that includes two encoders, a pair of extended brackets, and a pair of 42×19mm wheels—just pick the particular micro metal gearmotor that best suits your application and you have a solution for closed-loop motor control.
Note: This bracket also works with the 1000:1 micro metal gearmotors, but because of its longer gearbox, it does not fully enclose the exposed gears the way it does on the other micro metal gearmotors. This bracket with our quadrature encoder when used with the 1000:1 micro metal gearmotor.
