The Pololu 4.4:1 Metal Gearmotor 25Dx63L mm HP 12V w/ 48 CPR Encoder is a high-performance gearmotor that integrates a 12 V brushed DC motor with a 4:1 metal spur gearbox. It features a 48 CPR quadrature encoder on the motor shaft, delivering 211.2 counts per revolution of the gearbox's output shaft. The gearmotor is cylindrical, with a diameter slightly under 25 mm, and includes a D-shaped output shaft measuring 4 mm in diameter and extending 12.5 mm from the gearbox face plate.

This gearmotor is part of a versatile range of cylindrical brushed DC gearmotors, all sharing a 25 mm diameter case and a 4 mm diameter gearbox output shaft, facilitating easy interchangeability to meet varying design requirements. The motor and encoder can be acquired separately, and versions without the encoder are also available. The encoder utilizes a two-channel Hall effect sensor to detect the rotation of a magnetic disk on the motor shaft, providing a resolution of 48 counts per revolution.

The gearmotor's face plate is equipped with two mounting holes threaded for M3 screws, compatible with a custom-designed 25D mm metal gearmotor bracket for secure mounting. The 4 mm diameter gearbox output shaft is compatible with Pololu multi-hub wheels and the Pololu universal aluminum mounting hub, allowing for the attachment of larger wheels or custom mechanisms. A variety of motor drivers and controllers are available to complement these gearmotors, ensuring optimal performance across different applications.
