Overview

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 (rotation can start at voltages as low as 0.5 V). Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor. The plastic gearbox is protected by a built-in safety clutch that will typically slip before the gear teeth can shear (typically when the load exceeds around 25 oz-in, or 2 kg-cm).

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 available with an extended motor shaft that protrudes from the rear of the motor by approximately 4.5 mm. This second shaft has a diameter of 1.5 mm and rotates at the same speed as the input to the gearbox, offering a way to add a custom-built encoder 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 Pololu's micro metal gearmotors and are compatible with many Pololu wheels and Pololu's 3 mm universal mounting hubs. Pololu 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. These geamotors all work with Pololu's wide and tall mounting brackets for mini plastic gearmotors.

Details for item #1593

This item has a low-power motor (800 mA stall current), a 180:1 gearbox, and a 3 mm diameter “D”-shaped output shaft that is perpendicular to the motor shaft. The motor shaft does not extend past the base of the motor.
