19:1 Metal Gearmotor 37Dx68L mm 24V with 64 CPR Encoder (Helical Pinion)

Pololu presents a robust 24V brushed DC gearmotor, equipped with a 18.75:1 metal gearbox and an integrated quadrature encoder. The encoder provides a resolution of 64 counts per revolution of the motor shaft, translating to a whopping 1200 counts per revolution of the gearbox's output shaft. The gearbox predominantly consists of spur gears, with the first stage featuring helical gears for noise reduction and enhanced efficiency. The gearmotor has a 16mm long, 6mm diameter D-shaped output shaft. For those who prefer, a version without an encoder is also available.

The gearmotor's power and precision make it a versatile choice for a variety of applications. Whether you're creating a robotics project, an automated system, or any other project requiring accurate motion control, this gearmotor is designed to deliver. Its integrated quadrature encoder provides high-resolution feedback that can be used to create closed-loop control systems, adding precision to your project.

One of the key benefits of this gearmotor is its blend of power and efficiency. The helical gears in the first stage not only reduce noise, but also improve the efficiency of power transmission. This means you get a quieter, more effective operation, making it ideal for applications where noise levels matter.

Key specifications include a voltage of 24V, no-load performance of 530 RPM and 100 mA, and stall extrapolation of 9.5 kg⋅cm (130 oz⋅in), 3 A. This combination of specs ensures that the gearmotor delivers consistent, reliable performance, even in demanding conditions.
