This gearmotor consists of a medium-power, 12 V brushed DC motor combined with a 171.79:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 8245.92 counts per revolution of the gearbox output shaft. The gearmotor is cylindrical, with a diameter just under 25 mm, and the D-shaped output shaft is 4 mm in diameter and extends 12.5 mm from the face plate of the gearbox. At 12V, the speed is 7900 rpm before the motor decelerates.
Warning: Do not screw too far into the mounting holes as the screws can hit the gears. CQRobot recommend screwing no further than 6 mm (0.24″) into the screw hole.
