The 20.4:1 Metal Gearmotor 25Dx65L mm LP 12V with 48 CPR Encoder from Pololu is a robust and compact gearmotor. It features a low-power, 12V brushed DC motor, paired with a 20.4:1 metal spur gearbox for enhanced torque and speed control. The gearmotor also includes a built-in 48 CPR quadrature encoder that delivers 979.62 counts per revolution of the output shaft. With a cylindrical shape of just under 25mm in diameter, this gearmotor fits conveniently in a variety of applications. The D-shaped output shaft, which is 4mm in diameter, extends 12.5mm from the gearbox's faceplate. The gearmotor is also available without an encoder.
Key specifications of this gearmotor include a voltage of 12V, a no-load performance of 280 RPM and 60 mA, and a stall extrapolation of 2.4 kg⋅cm (33 oz⋅in) at 0.9 A. These specifications make it an excellent choice for projects that require precise movement and control.
The 20.4:1 Metal Gearmotor is ideal for a wide range of applications. It can be used in robotics for precise movement and control, in automated machinery for reliable and consistent performance, or in any project that requires a compact, yet powerful motor. The built-in encoder provides precise feedback on the motor's position, making it easy to implement accurate control systems.
One of the unique properties of this gearmotor is its combination of low-power consumption and high performance. The metal spur gearbox enhances the torque, allowing the motor to deliver efficient performance even at low power. Furthermore, the integrated quadrature encoder provides precise and reliable feedback, making it easier to achieve accurate control and positioning in your projects.
