34:1 Metal Gearmotor 25Dx52L mm HP with 48 CPR Encoder

This cylindrical, 2.54" x 0.98" x 0.98" gearmotor uses a brushed DC motor with extra-strong magnets and a 34.014:1 metal gearbox to deliver a lot of power in a relatively small package. It has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 1633 counts per revolution of the gearbox’s output shaft. These units have a 0.315"-long, 4 mm-diameter D-shaped output shaft. We also carry a lower-power version of this gearmotor and a version without an encoder. Key specs at 6 V: 285 RPM and 450 mA free-run, 60 oz-in (4.3 kg-cm) and 6 A stall.
