CQRobot Ocean: 34.01:1 LP Metal DC Geared-Down Motor 25Dx66.5L mm 3W/6V with 48 CPR Encoder and Fix Bracket. 170 RPM/3.5 kg (50 oz), D-shaped Output Shaft 4 mm/12.5 mm (Diameter/Length).

This gearmotor consists of a low-power, 6 V brushed DC motor combined with a 34.014:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 1632.67 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. A two-channel Hall effect encoder is used to sense the rotation of a magnetic disk on a rear protrusion of the motor shaft. The quadrature encoder provides a resolution of 48 counts per revolution of the motor shaft when counting both edges of both channels. To compute the counts per revolution of the gearbox output, multiply the gear ratio by 48. In general, these kinds of motors can run at voltages above and below their nominal voltages (they can begin rotating at voltages as low as 1 V); lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.
