Solarbotics GM6 120:1 Mini Gear Motor Offset Output

This 120:1 gearmotor is very compact and weighs only 0.7 ounces (20 grams) — perfect for building a quick, miniature robot.

This gearmotor starts rotation at 0.58 V, drawing only 46.5 mA at 7 RPM. At 5 V, the gearbox and motor provide 20 oz-in of torque and 145 RPM. The free-running current is 88 mA, and the stall current is 610 mA. The low-current motor is a perfect match for our qik 2s9v1 dual serial motor controller.

This gearmotor comes pre-assembled, with the gears fully enclosed. A clutch limits the output torque to approximately 25 oz-in (which is produced at 6.5 V, drawing 650 mA) to protect the gearbox and motor. The unit has one mounting hole, and the chrome-finish output shaft is splined with a 0.08" (2 mm)-crest diameter.

A custom plastic wheel is available for this gearmotor, as well as a LEGO wheel adapter that allows it to be used with a variety of LEGO wheels.

For a similar, less expensive version of this gearmotor, see the Pololu 120:1mini plastic gearmotor offset output. For a version of this gearmotor with a 90 degree output shaft, see the GM7 gearmotor. For a similar but larger gearmotor, see the GM2 gearmotor (224:1) and the GM8 gearmotor (143:1).
