Pololu 19:1 Metal Gearmotor 37Dx68L mm 12V with 64 CPR Encoder (Helical Pinion)

Pololu brings you a robust 12V brushed DC gearmotor with a high-quality metal gearbox and a quadrature encoder. This gearmotor operates with an 18.75:1 metal gearbox and offers a resolution of 64 counts per revolution of the motor shaft. This translates to 1200 counts per revolution of the output shaft. The gearbox is primarily composed of spur gears but features helical gears for the first stage, ensuring reduced noise and enhanced efficiency. The gearmotor has a 16mm long, 6mm diameter D-shaped output shaft. It's also available without an encoder if that suits your needs better. The gearmotor is perfect for projects that require precise control of speed and position. It can be used in robotics, automation systems, and other applications where high torque, high resolution, and low noise are critical. The quadrature encoder provides accurate feedback on speed and direction, making it possible to implement sophisticated control algorithms.One of the unique features of this gearmotor is the use of helical gears in the first stage of the gearbox. Helical gears have a larger contact surface than spur gears, which results in smoother operation and less noise. This makes the gearmotor an excellent choice for applications where noise is a concern.Key specifications:voltageno-load performancestall extrapolation12 V 530 RPM, 200 mA 8.5 kg⋅cm, 5.5 A The gearmotor operates at a voltage of 12V and offers a no-load performance of 530 RPM with a current draw of 200 mA. The stall extrapolation is 8.5 kg⋅cm and 5.5 A, providing powerful performance for your projects.
