378:1 Metal Gearmotor 25Dx73L mm LP 6V with 48 CPR Encoder

Pololu presents a powerful and compact gearmotor, a blend of a low-power, 6V brushed DC motor and a 377.93:1 metal spur gearbox. This gearmotor includes a 48 CPR quadrature encoder on its motor shaft, providing 18,140.79 counts per revolution of the gearbox's output shaft. The cylindrical gearmotor measures just under 25mm in diameter, and its D-shaped output shaft is 4mm in diameter, extending 12.5mm from the faceplate of the gearbox. A version of this gearmotor is also available without an encoder.

This gearmotor is perfect for a wide range of applications. Whether you're building a robotics project, a model vehicle, or any other motion-sensitive creation, the gearmotor's compact size and high power output make it a suitable choice. The integrated encoder provides precise control over the speed and direction of the output shaft, making it easier to achieve precise movements and alignments in your projects.

Key specifications for this gearmotor include a 6V operating voltage, 16 RPM no-load performance, and 120 mA current draw. The stall extrapolation is a hefty 25 kg⋅cm (equivalent to 350 oz⋅in) with a 2.0 A current draw. These specifications highlight the gearmotor's balance of power, performance, and efficiency.

What sets this gearmotor apart is its high-quality metal spur gearbox. This feature ensures durability and longevity, even under high-stress applications. The D-shaped output shaft also ensures a secure connection to your project, reducing the risk of slippage or misalignment. The integrated 48 CPR quadrature encoder offers high-resolution feedback, allowing for accurate control in your applications.

In conclusion, Pololu's gearmotor is a compact, powerful, and efficient solution for your motion-based projects. Its robust construction and integrated encoder make it a reliable choice for demanding applications.
