This gearmotor is a miniature (0.94 x 0.39 x 0.47 in.), high-power brushed DC motor with 50:1 metal gearbox, similar to Sanyo's popular 12mm gearmotors. These units have a 0.365 inch-long, 3mm-diameter D-shaped output shaft.
These tiny brushed DC gearmotors are intended for use at 6V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3-9V range (rotation can start at voltages as low as 0.5V). Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.
The gearbox has a long (0.365 in. or 9.27mm), 3mm-diameter D-shaped metal output shaft, and the brass faceplate has two mounting holes threaded for M1.6 screws (1.6mm diameter, 0.35mm thread pitch). The gearmotor weighs approximately 0.35 oz (10 g).
