This gearmotor is a powerful 6V or 12V brushed DC motor with a 210:1 metal gearbox and an integrated quadrature encoder that provides a resolution of 64 counts per revolution of the motor shaft, which corresponds to 13440 counts per revolution of the gearboxot is output shaft. These units have a 16 mm-long, 6 mm-diameter D-shaped output shaft. At 12V, the speed is 11,000 rpm before the motor decelerates, and at 6V, the speed is 5500 rpm before the motor decelerates. Note: Do not screw too far into the mounting holes as the screws can hit the gears. We recommend screwing no more than 3mm (0.12″) into the screw hole.
