Loading... Please wait...This motor from Pololu has a 0.275" (7 mm) D-shaped metal output shaft that matches the Pololu wheel 42x19mm and 32x7mm. The face plate has two mounting holes threaded for M2 screws.
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.
