- Ensures reliable 8245.92 counts per revolution
- Fits compact spaces with sub-25 mm diameter
- Ideal for robotics and automation systems
The Pololu 172:1 Metal Gearmotor 25Dx71L mm LP 12V w/ 48 CPR Encoder is a sophisticated component designed for precision and efficiency in motion control applications. This gearmotor integrates a low-power, 12-volt brushed DC motor with a robust 171.79:1 metal spur gearbox, ensuring reliable performance in demanding environments. The inclusion of a 48 CPR quadrature encoder on the motor shaft enhances its functionality by providing an impressive 8245.92 counts per revolution of the gearbox’s output shaft, allowing for precise monitoring and control of rotational position and speed.
The gearmotor features a cylindrical design with a diameter slightly less than 25 mm, making it compact and suitable for a variety of applications where space is a constraint. The D-shaped output shaft, measuring 4 mm in diameter and extending 12.5 mm from the gearbox's faceplate, facilitates easy integration with other mechanical components.
This gearmotor is ideal for projects requiring accurate feedback and control, such as robotics, automation systems, and other electromechanical applications. Its design ensures durability and consistent performance, making it a reliable choice for engineers and developers seeking high-quality motion control solutions.
