Description
- Pololu 172:1 Metal Gearmotor 25Dx71L mm MP 12V w/ 48 CPR Encoder
- Integrates precise 48 CPR encoder
- Delivers 18 kg⋅cm stall torque
- Cylindrical, compact 25 mm design
- Offers 8245.92 counts per revolution
- Ideal for robotics and automation
The Pololu 172:1 Metal Gearmotor 25Dx71L mm MP 12V w/ 48 CPR Encoder is a sophisticated component designed for applications requiring precise control and high torque. This gearmotor integrates a medium-power, 12 V brushed DC motor with a robust 171.79:1 metal spur gearbox. It features an advanced 48 CPR quadrature encoder mounted on the motor shaft, delivering an impressive 8245.92 counts per revolution of the gearbox’s output shaft, which ensures exceptional accuracy in motion control tasks.
The gearmotor's cylindrical form factor, with a diameter slightly less than 25 mm, allows for easy integration into various mechanical systems. The D-shaped output shaft, measuring 4 mm in diameter and extending 12.5 mm from the gearbox's face plate, provides a reliable interface for connecting to other components. This model is particularly suitable for projects that demand high precision and reliability, such as robotics and automation systems.
Note: Ensure proper handling and installation to prevent damage or injury due to the high torque output.
