These light-weight brackets (approximately 2 g each) are specifically designed for our larger Pololu plastic gearmotors (228:1 offset, 120:1 offset, 200:1 90-degree, and 120:1 90-degree). Each bracket features two mounting holes and one mounting slot intended for #4-size screws (not included). We also offer an extended version of this bracket that allows for even more mounting options and might work better for particular applications.
A total of four 1? long #2-56 screws, for use with the 228:1 offset and 120:1 offset plastic gearmotors, and four 0.75? long #2-56 screws, for use with the 200:1 90-degree and 120:1 90-degree plastic gearmotors, are included. Two #2-56 hex nuts are also included for each bracket. Only two screws are used to mount a motor to each bracket, as shown in the pictures below:
These brackets also work with the Solarbotics plastic gearmotors (GM2, GM3, GM8, and GM9), although different length mounting screws might be required.
