Micro Metal Geared motor w/Encoder – 6V 530RPM 30:1

Micro Metal Gearmotor 30:1 with Encoder combines compact DC motor performance with integrated speed feedback for precise motion control. A built‑in Hall encoder continuously monitors rotational speed, enabling closed‑loop control in robotics, automation prototypes, and intelligent mobility systems. The miniature gearbox delivers high reduction efficiency while maintaining a small footprint suitable for tight chassis layouts. A durable metal D‑profile output shaft ensures stable mechanical coupling with common robot wheels, while threaded mounting holes simplify installation in compact drive assemblies. Compatibility with the 2WD miniQ Robot Chassis makes this geared encoder motor an excellent choice for mobile robotics experimentation and educational development platforms.

Integrated Hall Encoder for Real‑Time Feedback

An onboard Hall sensor array measures shaft rotation and produces high‑resolution pulse feedback for accurate speed detection. The updated encoder design incorporates 7 pole pairs, increasing measurement resolution significantly compared with earlier versions. Average output pulses can reach up to 7 × 2 × 30 pulses per revolution, enabling precise PID speed regulation and reliable odometry calculations. This feedback‑enabled micro gearmotor becomes a practical actuator for robotics platforms requiring accurate velocity monitoring and closed‑loop motion control.

Compact Metal Gear Train with 30:1 Reduction

A precision metal gearbox provides a 30:1 reduction ratio, converting high‑speed motor rotation into stable torque output suitable for miniature robotic drivetrains. The reducer section measures only 9.0 mm in length, allowing dense mechanical integration inside small robot chassis or custom mechanisms. Durable internal gears improve longevity under continuous operation, while the gearbox architecture maintains smooth transmission with minimal backlash for reliable robotic movement.

Mechanical Compatibility with Standard Micro Robot Wheels

A 0.354 inch (9.0 mm) D‑profile metal output shaft ensures secure wheel attachment and efficient torque transfer. The shaft format supports widely used Pololu‑style wheels including 42 × 19 mm and 32 × 7 mm sizes, simplifying drivetrain assembly. A brass faceplate provides two threaded M1.6 mounting holes (1.6 mm diameter, 0.35 mm thread pitch), enabling direct installation or use with compatible mounting brackets that protect exposed gears while maintaining rigid alignment.

Such a miniature encoder gearmotor fits well in compact robotics platforms, autonomous vehicles, classroom robotics kits, and STEM Education projects requiring speed feedback and accurate motor control. Small‑scale mobile robots, research prototypes, and educational drive systems benefit from the balance of torque, compact dimensions, and encoder‑based motion sensing provided by this integrated drive module.
