172:1 Metal Gearmotor 25Dx71L mm LP 6V with 48 CPR Encoder

The 172:1 Metal Gearmotor 25Dx71L mm LP 6V with 48 CPR Encoder is a robust, compact gearmotor that combines a low-power 6V brushed DC motor with a 171.79:1 metal spur gearbox. It features an integrated 48 CPR quadrature encoder on the motor shaft, providing an impressive 8245.92 counts per revolution of the gearbox's output shaft. The cylindrical gearmotor has a diameter just under 25mm, while the D-shaped output shaft is 4mm in diameter and extends 12.5mm from the face plate of the gearbox. For those who prefer a simpler setup, Pololu also offers this gearmotor without an encoder.

The 172:1 Metal Gearmotor is perfect for a wide range of applications. Use it in robotics for precise movement control, or in automated systems where accurate positioning is key. With its integrated encoder, this gearmotor allows for precise speed and distance measurement, making it an excellent choice for projects that require high precision.

This gearmotor is not only versatile, but also powerful and efficient. Operating at 6 volts, it delivers a no-load performance of 35 RPM and 120 mA. In case of stall, the gearmotor can handle up to 14 kg⋅cm, with a current draw of 2.0 A. Despite its power, the gearmotor maintains a compact form factor, making it easy to integrate into your projects.
