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, 4 mm-diameter D-shaped output shaft. We also carry a lower-power version of this gearmotor.

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