120:1 Mini Plastic Gearmotor, Offset 3mm D-Shaft Output

120:1 Mini Plastic Gearmotor, Offset 3mm D-Shaft Output.
This compact, inexpensive plastic 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 gearbox has a 9.7mm-long, 3 mm-diameter D-shaped output shaft that is offset from but parallel to the motor shaft, and a built-in safety clutch helps protect the gears from excessive loads.
