Mini Plastic Gearmotors

These brushed DC gearmotors are compact and affordable — perfect for building a quick, miniature robot. They are intended for use at 4.5 V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should operate comfortably in the 3 V to 6 V range. The plastic gearbox is protected by a built-in safety clutch that will typically slip before the gear teeth can shear.

The mini plastic gearmotor family offers two output shaft orientations relative to the motor shaft (offset and 90°), two motor options (normal and high-power, or HP for short), and two gearbox options (120:1 and 180:1). The 120:1 versions are white and the 180:1 versions are yellow. Additionally, some versions of these gearmotors are also available with an optional extended motor shaft, which allows for the addition of encoders like our magnetic encoder pair kit to provide motor speed or position feedback.

Note: The stall torque values listed are approximate, and the built-in safety clutch might start slipping at lower torques.

The gearmotors in the table above all have a 3 mm diameter D-shaft output. These shafts are just like the ones on our micro metal gearmotors and are compatible with many Pololu wheels and our 3 mm universal mounting hubs. We also carry two low-power, 120:1 mini plastic gearmotors with 2 mm diameter spline outputs: 90° 2mm spline output and offset 2mm spline output.
