20.4:1 Metal Gearmotor 25Dx65L mm MP 12V with 48 CPR Encoder

The 20.4:1 Metal Gearmotor 25Dx65L mm MP 12V with 48 CPR Encoder is a versatile, medium-power gearmotor that combines a 12V brushed DC motor with a 20.4:1 metal spur gearbox. It features an integrated 48 CPR quadrature encoder on the motor shaft, providing 979.62 counts per revolution of the gearbox's output shaft. The gearmotor has a cylindrical shape with a diameter slightly less than 25mm. The D-shaped output shaft measures 4mm in diameter and extends 12.5mm from the gearbox's faceplate. Pololu also offers this gearmotor without an encoder.

The key specifications of this gearmotor include a voltage of 12V, no-load performance of 380 RPM and 100 mA, and stall extrapolation of 3.2 kg⋅cm (44 oz⋅in), 1.8 A.

With its compact size and powerful performance, this gearmotor is perfect for a wide range of applications. For example, it can be used in robotics, where precise movement and speed control are essential. The integrated encoder provides accurate feedback on the motor's position, allowing for precise control over the speed and direction of the motor. This makes it an excellent choice for projects that require precise motion control.

Furthermore, the robust metal gearbox enhances the durability and longevity of the gearmotor, making it suitable for demanding applications. The D-shaped output shaft ensures secure and stable connection with the load. With its excellent performance and durable construction, the 20.4:1 Metal Gearmotor is a reliable choice for your next project.
