Gearmotor Dimensions:

This brushed DC motor has a long (0.365" or 9.27 mm, not 8mm as shown in the drawing below), 3 mm-diameter D-shaped metal output shaft that matches Pololu's assortment of Pololu wheels and the Solarbotics RW2 rubber wheel. Alternatively, you can use the Pololu universal mounting hub to mount custom wheels and mechanism to the micro metal gearmotor’s output shaft.

The brass faceplate has two mounting holes threaded for M2 screws (2 mm diameter, 0.4 mm thread pitch). This gearmotor works with Pololu's 15.5D mm metal gearmotor brackets.

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

These motors are intended for use at 9 V, which means you can get more speed and torque out of this motor than is listed in the 6 V specs. In general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 12 V range (the motor can begin rotating at voltages as low as 0.5 V). 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 14 oz-in (1 kg-cm).

Selecting the Right Gearmotor

Pololu offer a wide selection of metal gearmotors that offer different combinations of speed and torque. Pololu's metal gearmotor comparison table can help you find the motor that best meets your project’s requirements.
