20.4:1 Metal Gearmotor 25Dx50L mm HP

This cylindrical, 1.97" x 0.98" x 0.98" gearmotor uses a brushed
DC motor with extra-strong magnets and a 20.4:1 metal gearbox to deliver a lot of power in a relatively small package.
These units have a 0.315"-long, 4mm-diameter D-shaped output shaft. We also carry a lower-power version of this gearmotor.

Key specs at 6V: 480RPM and 450mA free-run, 36oz-in (2.6kg-cm) and 6A stall.

These motors are intended for use at 6V. In general, these kinds of motors can run
at voltages above and below this nominal voltage, so they should comfortably operate in the
3 – 9V range, though they can begin rotating at voltages as low as 1V.
Higher voltages could start negatively affecting the life of the motor.

These gearmotors have output shafts with a diameter of 4mm.
The Pololu universal aluminum mounting hub 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 left picture below).
These are the same type of motors used in the Wild Thumper all-terrain chassis,
and the gearbox’s output shaft works directly with the 120mm-diameter Wild Thumper wheels.
