This 1.64" x 0.80" x 0.80" gearmotor is a high-quality, low-current motor with 25:1 metal gearbox. These units have a 0.276"-long, 4 mm-diameter D-shaped output shaft.
The face plate has two mounting holes threaded for M2.5 screws. You can use our custom-designed 20D metal gearmotor bracket (pictured to the right) to mount the gearmotor to your project via these mounting holes and the screws that come with the bracket.
Please note that the 20Dx44L mm line of gearmotors have output shafts with a diameter of 4 mm. The Pololu universal aluminum mounting hub for 4mm shafts can be used to mount custom wheels and mechanisms to the gearmotor’s output shaft.

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.
Note: This motor is a lower-current, lower-power version of our 25:1 metal gearmotor 20Dx44L mm.
