These small brushed DC gearmotors can deliver a lot of power for their size. This version has a 56:1 metal gearbox with a 0.276"-long, 4 mm-diameter D-shaped output shaft.
Key specs at 6 V: 250 RPM and 250 mA free-run, 45 oz-in (3.3 kg-cm) and 3.3 A stall.
The 20D mm line of brushed DC gearmotors all have the same dimensions except for the length of the gearbox, and they are intended for use at 6 V. In general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range. Higher voltages could start negatively affecting the life of the motor, and lower voltages might not be practical. Four different gear ratios are available.
The gearmotor face plate has two mounting holes threaded for M2.5 screws, and you can use our custom-designed 20D mm metal gearmotor bracket (shown in the left picture below) to mount the gearmotor to your project via these mounting holes and the screws that come with the bracket.
This gearmotor has an output shaft with a diameter of 4 mm; the Pololu universal aluminum mounting hubs for 4mm shafts can be used to mount our larger Pololu wheels (60mm-, 70mm-, 80mm-, and 90mm-diameter) or custom wheels and mechanisms to the gearmotor’s output shaft (see the right picture above). Alternatively, you could use our 4mm scooter wheel adapter to mount many common scooter, skateboard, and inline skate wheels to the gearmotor’s output shaft, and you can use our 12mm hex wheel adapter to use this motor with many common hobby RC wheels. The gearbox’s output shaft also works directly with the 120mm-diameter Wild Thumper wheels.
