Pololu 50:1 Metal Gearmotor 37Dx70L mm 12V with 64 CPR Encoder (Helical Pinion)

The 50:1 Metal Gearmotor 37Dx70L mm 12V with 64 CPR Encoder (Helical Pinion) is a robust gearmotor featuring a 12V brushed DC motor, a 50:1 metal gearbox, and an in-built quadrature encoder. The encoder offers a resolution of 64 counts per revolution of the motor shaft, translating to 3200 counts per revolution of the gearbox's output shaft. The majority of the gearbox is made of spur gears, but it also includes helical gears in the first stage, making it quieter and more efficient. The gearmotor has a 16 mm-long, 6 mm-diameter D-shaped output shaft.This gearmotor is perfect for projects that require high torque and precision. The integrated encoder allows for precise control of speed and positioning, making it ideal for robotics, automated systems or any application where accurate motion control is crucial.One of the key benefits of this gearmotor is its efficiency and quiet operation, thanks to the helical gears in the first stage of the gearbox. This makes it suitable for applications where noise reduction is a priority, such as in office or domestic environments.Key specifications:VoltageNo-load PerformanceStall Extrapolation12 V 200 RPM, 200 mA 21 kg⋅cm (approx. 2,058 g⋅cm), 5.5 A Note: This gearmotor is also available without an encoder.
