120:1 Mini Plastic Gearmotor, Offset 2mm Spline Output
This compact, inexpensive, low-current gearmotor (brushed DC motor with a 120:1 reduction gearbox) is well suited for use in small robots. While intended for operation at 4.5 V, it should run comfortably in the 3 V to 6 V range. The splined output shaft has a crest diameter of 2 mm and is offset from but parallel to the motor shaft. The gearbox is protected by a built-in safety clutch that helps protect the gears from excessive loads.
