Description
The Pololu 12V 34:1 Metal Gearmotor MP with 48 CPR Encoder is a medium-power 12V brushed DC motor integrated with a durable 34.014:1 metal spur gearbox and a quadrature encoder for precise position and speed feedback.
This compact cylindrical gearmotor offers a perfect balance of torque, speed, and precision, making it ideal for robotics, automation systems, and motion control applications. The built-in 48 CPR encoder on the motor shaft provides 1632.67 counts per revolution of the gearbox output, ensuring highly accurate motion feedback for closed-loop control systems.
The motor’s metal gearbox, D-shaped 4mm output shaft, and standard JST 6-pin encoder connector ensure easy mechanical and electrical integration into your robotics project or automation setup.
