Mini Metal Gearmotor Details (16Dx32L)

Gearmotor Dimensions:

This motor has a 0.275" (7 mm) D-shaped metal output shaft that matches the Pololu wheel 32×7mm, Pololu wheel 42×19mm, and Solarbotics RW2 rubber wheel. Alternatively, the hub in the picture can be used to mount custom wheels and mechanisms to the gearmotor’s output shaft.

The face plate has two mounting holes threaded for M2 screws. You can use our custom-designed mini metal gearmotor bracket (pictured below) to mount the gearmotor to your project via these mounting holes and the screws that come with the bracket.

These 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 – 9 V range. Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.
