30:1 Micro Metal Gearmotor

This gearmotor is a miniature (0.94" x 0.39" x 0.47"), low-current brushed DC motor with 30:1 metal gearbox, similar to Sanyo’s popular 12 mm gearmotors. These units have a 0.365"-long, 3 mm-diameter D-shaped output shaft.

Key specs at 6 V: 440 RPM and 40 mA free-run, 4 oz-in (0.3 kg-cm) and 0.36 A stall.

These 30:1 ratio motors are used in the popular 3Pi Robot. So, if you have damaged your 3Pi Robot motor, this is the replacement you will need.

These tiny, high-quality 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 (rotation can start 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. All of the micro metal gearmotors have the same physical dimensions, but they come in a wide range of gear ratios—from 5:1 up to 1000:1—and let you choose between two different motors: high-power (HP) and standard.

The gearbox has a long (0.365" or 9.27 mm), 3 mm-diameter D-shaped metal output shaft, and the brass faceplate has two mounting holes threaded for M1.6 screws (1.6 mm diameter, 0.35 mm thread pitch). It weighs approximately 0.35 oz (10 g).
