The Pololu 378:1 Metal Gearmotor 25Dx73L mm LP 6V w/ 48 CPR Encoder is a sophisticated component designed for precision motion control applications. This gearmotor integrates a low-power, 6 V brushed DC motor with a robust 377.93:1 metal spur gearbox, ensuring high torque output. The inclusion of a 48 CPR quadrature encoder on the motor shaft allows for precise feedback, providing 18,140.79 counts per revolution of the gearbox’s output shaft, which is essential for accurate positioning and speed control.

The gearmotor features a cylindrical design with a diameter of just under 25 mm, and a D-shaped output shaft that is 4 mm in diameter, extending 12.5 mm from the gearbox face plate. This design facilitates compatibility with various mounting options and accessories, such as Pololu multi-hub wheels and universal aluminum mounting hubs, enabling versatile integration into diverse mechanical systems.

The encoder utilizes a two-channel Hall effect sensor to detect the rotation of a magnetic disk, offering a resolution of 48 counts per revolution of the motor shaft. This setup provides critical data on motor speed and direction, which is vital for applications requiring precise control. The motor and encoder are equipped with six color-coded leads terminated by a 1×6 female header, compatible with standard 0.1″ male headers.

The gearmotor's face plate includes two mounting holes threaded for M3 screws, allowing secure attachment using custom-designed brackets. This feature, combined with its adaptable output shaft, makes the gearmotor suitable for a wide range of applications in robotics and automation.
