This cylindrical, 2.69″ × 0.98″ × 0.98″ brushed DC gearmotor with a 171.79:1 metal gearbox is a lower-current alternative to our 25D mm HP gearmotors. It has an integrated 48 CPR quadrature encoder on the motor shaft, which corresponds to 8246 counts per revolution of the gearbox’s output shaft. These units have a 0.315"-long, 4 mm-diameter D-shaped output shaft. This gearmotor is also available without an encoder.

Key specs at 6 V: 33 RPM and 80 mA free-run, 170 oz-in (12.2 kg-cm) and 2.2 A stall.
