## Description

This 120:1 brushed DC 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 Pololu's [qik 2s9v1 dual serial motor controller](https://core-electronics.com.au/pololu-qik-2s9v1-dual-serial-motor-controller.html).

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](https://core-electronics.com.au/catalog/product/view/sku/POLOLU-190) is available for this gearmotor, as well as a [LEGO wheel adapter](https://core-electronics.com.au/2mm-shaft-adapter.html) 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](https://core-electronics.com.au/120-1-mini-plastic-gearmotor-offset-2mm-spline-output.html). For a version of this gearmotor with a 90 degree output shaft, see the [GM7 gearmotor](https://core-electronics.com.au/solarbotics-gm7-120-1-mini-gear-motor-90-deg-output.html). For a similar but larger gearmotor, see the [GM2 gearmotor](https://core-electronics.com.au/solarbotics-gm2-224-1-gear-motor-offset-output.html) (224:1) and the [GM8 gearmotor](https://core-electronics.com.au/solarbotics-gm8-143-1-gear-motor-offset-output.html) (143:1).
