This 120:1 gearmotor (gearbox with motor) is a very compact 2.09" x 0.51" x 0.75" (53mm x 13mm x 19mm), and weighs only 0.7 ounces (20 grams)  perfect for building a quick, miniature robot.

This gearmotor starts rotation at 0.58 volts, drawing only 46.5 mA at 7 RPM. At 5V, 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 micro 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 6.5V, drawing 650mA) to protect the gearbox and motor. The chrome-finish output shaft is splined with a 0.8" (2mm)-crest diameter. The unit has no mounting holes.

Custom plastic wheels (BR770190, BR770191, BR770360, BR770361) are available for this gearmotor.
