Micro Metal Geared motor w/Encoder - 6V 310RPM 50:1

Micro Metal Gearmotor 50:1 with Encoder integrates a compact DC motor, precision metal gearbox, and a built‑in Hall encoder for accurate motion feedback in robotics and automation systems. The miniature gearmotor delivers high rotational speed from the core motor combined with a 50:1 reduction gearbox, producing stable torque suitable for small mobile robots and mechanism control. Integrated encoder feedback generates pulse signals corresponding to shaft rotation, enabling real‑time speed monitoring and closed‑loop control. A durable D‑profile metal output shaft supports common small robot wheels and drive hubs, making this compact drivetrain component well suited for educational robotics platforms and embedded motion systems.

High‑Resolution Integrated Encoder Feedback

An onboard Hall sensor encoder measures motor rotation and outputs pulse signals for precise motion tracking. The upgraded Hall sensor contains seven pole pairs, increasing encoder resolution significantly and producing up to 7× higher pulse counts compared with earlier versions. Average encoder output can reach approximately 7×2×50 pulses per revolution, enabling accurate speed measurement and position estimation. Such feedback capability supports closed‑loop motor control, PID speed regulation, and robotics navigation tasks requiring reliable rotational sensing.

Compact Gearmotor with Efficient 50:1 Reduction

A high‑speed DC motor core operating at 15000 RPM combines with a precision 50:1 metal gearbox to convert rotational speed into usable torque for robotic mechanisms. The gearbox maintains stable output while reducing motor speed to a practical operating range. This miniature drivetrain architecture provides a good balance between torque, speed, and efficiency, making the motor suitable for lightweight robotic vehicles, automated mechanisms, and compact motion systems where space and weight constraints are critical.

Robotics‑Ready Mechanical Design

A 9.0 mm long D‑profile metal output shaft ensures secure coupling with small robot wheels such as 42×19 mm or 32×7 mm Pololu‑style wheels. A brass faceplate with threaded M1.6 mounting holes enables direct installation on brackets or frames. Compatibility extends to dedicated mounting brackets designed for this gear motor, including extended brackets that protect exposed gears while supporting wheels with recessed hubs. Mechanical compatibility also includes the 2WD miniQ Robot Chassis, simplifying integration into compact mobile robot platforms.

This encoder‑equipped micro gearmotor serves as a reliable motion actuator for robotics experimentation, compact mobile robots, educational engineering projects, and precision mechanical prototypes requiring both torque output and real‑time rotation feedback.
