75:1 Metal Gearmotor 25Dx69L mm LP 12V with 48 CPR Encoder

The 75:1 Metal Gearmotor 25Dx69L mm LP 12V with 48 CPR Encoder is a high-quality gearmotor that combines a low-power, 12V brushed DC motor with a 74.83:1 metal spur gearbox. The unit is compact and cylindrical, measuring just under 25mm in diameter. The D-shaped output shaft is 4mm in diameter and extends 12.5mm from the face plate of the gearbox. What sets this gearmotor apart is the integrated 48 CPR quadrature encoder on the motor shaft, providing an impressive 3591.84 counts per revolution of the gearbox’s output shaft.

This gearmotor is a perfect choice for those who require precision and power in a compact package. The unit's key specifications are a voltage of 12V, a no-load performance of 75 RPM and 60 mA, and a stall extrapolation of 7.1 kg⋅cm (99 oz⋅in), 0.9 A. With these specifications, the gearmotor is suitable for a wide range of applications, from robotics to industrial machinery.

One of the benefits of this gearmotor is its integrated encoder. This allows for precise control of the motor's speed and direction, making it ideal for applications where accuracy is paramount. The encoder also provides feedback, allowing for adjustments to be made in real time to ensure optimal performance.

Another unique property of this gearmotor is its compact size. Despite its small diameter, the gearmotor packs a punch with its high torque and speed. This makes it a versatile choice for projects where space is at a premium.

For those who do not require the integrated encoder, Pololu also offers a version of this gearmotor without an encoder, allowing you to choose the right product for your specific needs.
