70:1 Metal Gearmotor 37Dx70L mm 24V with 64 CPR Encoder (Helical Pinion)

Pololu offers an impressive 24V brushed DC motor in the form of the 70:1 Metal Gearmotor 37Dx70L mm. This highly efficient gearmotor is equipped with a 70:1 metal gearbox and an integrated quadrature encoder. The encoder provides a resolution of 64 counts per revolution of the motor shaft, equating to 4480 counts per revolution of the gearbox's output shaft. The gearbox is primarily composed of spur gears, with helical gears included in the first stage to decrease noise and enhance efficiency. With a 16mm-long, 6mm-diameter D-shaped output shaft, this gearmotor is a versatile and reliable choice for a variety of applications. A version of this gearmotor without an encoder is also available.

The key specifications of the gearmotor are as follows:

Voltage: 24V

No-load Performance: 140 RPM, 100 mA

Stall Extrapolation: 31 kg⋅cm, 3 A

This gearmotor is an excellent choice for robotics, automation, and other applications where precise motion control is required. The integrated quadrature encoder provides high-resolution feedback that can be used for precise speed and position control. The helical gears in the first stage of the gearbox reduce noise and increase efficiency, making this gearmotor a quiet and energy-efficient choice.

Unique to this gearmotor is the combination of a high-power 24V brushed DC motor, a robust 70:1 metal gearbox, and an integrated quadrature encoder. This combination provides high torque, precise control, and efficient operation. The D-shaped output shaft is easy to connect to wheels, arms, and other mechanisms, making this gearmotor a versatile choice for a wide range of applications.
