These aluminum gearmotor brackets from Pololu let you securely mount the larger Pololu plastic gearmotors (228:1 offset, 120:1 offset, 200:1 90-degree, and 120:1 90-degree) to your project although at the time of writing we do not stock these motors at Technobots. However, these brackets do fit a number of other similar motors that we do stock at Technobots including:
These brackets are sold in pairs, and each bracket comes with two 1″ long and two 0.75″ long #2-56 screws for securing different size motors. Some motor types may require even longer screws than supplied. Each bracket also features two mounting holes and one mounting slot intended for #4-size screws (not included) although M3 screws will just about fit through.
We also offer an extended version of this bracket for even more mounting options.
