227:1 Metal Gearmotor 25Dx56L mm
This cylindrical, 2.2" x 0.98" x 0.98" brushed DC gearmotor with a 227:1 metal gearbox is a lower-current,
lower-speed alternative to our 25Dmm HP gearmotors.
These units have a 0.315"-long, 4mm-diameter D-shaped output shaft.
Key specs at 6V: 25RPM and 80mA free-run, 220oz-in (15.8kg-cm) and 2.2A stall.
(Note: stall torque and current specifications are theoretical values; stalling the motor is likely to damage the gearbox.)
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.
