Gearmotor Dimensions:

This motor has a long (0.365" or 9.27 mm, not 8mm as shown in the drawing below), D-shaped metal output shaft that matches the Pololu wheel 42×19 mm, Pololu wheel 32×7 mm, and Solarbotics RW2 rubber wheel. The brass faceplate has two mounting holes threaded for M1.6 screws (1.6 mm diameter, 0.35 mm thread pitch).

Note: this gearmotor is not compatible with our Sanyo-style micro gearmotor mounting brackets (products 989 and 1089).

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.

At 6 V, this gearmotor will have a no-load RPM of around 350 with a free-run current of 70 mA, a stall current of 1.5 A, and a stall torque of around 35 oz-in (2.52 kg-cm).

Pololu metal gearmotors arranged by size from left to right: micro, 100:1 and 24:1 mini, 35:1 mini, and 25:1 20Dx44L mm.
