The Pololu 150:1 Metal Gearmotor 37Dx73L mm w/ 64 CPR Encoder & Helical Pinion is a robust 12V brushed DC motor, equipped with a 150:1 metal gearbox and an integrated quadrature encoder. This encoder offers a resolution of 64 counts per revolution of the motor shaft, equating to 9600 counts per revolution of the gearbox’s output shaft. The gearbox is primarily constructed of spur gears, but it also incorporates helical gears in the first stage. This design choice reduces noise and enhances efficiency. The gearmotor features a 16 mm-long, 6 mm-diameter D-shaped output shaft.

The key specifications of this gearmotor include a voltage no-load performance stall extrapolation of 12 V 67 RPM, 200 mA 49 kg-cm (680 oz⋅in), 5 A. The precise gear ratio is 150:1.

The gearmotor is equipped with a two-channel Hall effect encoder, which 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 64 counts per revolution of the motor shaft when counting both edges of both channels.
