Micro Metal DC Geared Motor (6V 50RPM 250g*cm)

Micro Metal DC Geared Motor (6V 50RPM 250g*cm) delivers compact, high‑torque motion control for miniature robotics and mobile platforms. A precision 1:298 metal gearbox combined with a 6V DC motor produces stable low‑speed rotation and reliable torque in a lightweight 10g form factor. A long 9.27mm D‑shaped output shaft ensures secure wheel coupling while maintaining precise alignment during operation. Designed for compact robotic assemblies, this miniature gearmotor integrates smoothly with small drive systems, making the actuator well suited for educational robots, mobile prototypes, and compact automation mechanisms.

Precision Gear Reduction for Stable Low‑Speed Torque

A high 1:298 reduction ratio allows this compact DC gearmotor to convert motor speed into strong rotational torque while maintaining controlled output around 50RPM. Such gearing enables smooth motion for robotics platforms requiring accurate low‑speed driving and stable movement. Brass gearbox construction enhances durability and mechanical reliability, while controlled mechanical noise (≤50dB measured at 10cm) supports quieter operation during continuous movement or indoor robotics testing.

Mechanical Compatibility with Mini Robotics Platforms

A 9.27mm long D‑shaped metal output shaft matches Pololu‑style wheels including 42×19mm and 32×7mm models, providing secure coupling without slippage. Two M1.6 threaded mounting holes on the brass faceplate simplify mechanical integration into robot frames. This miniature drive motor works with the 2 wheels miniQ platform and can directly pair with the MiniQ Robot chassis Encoder and mounting bracket, supporting modular robotic chassis design.

Compact Form Factor for Lightweight Robot Design

A lightweight construction of approximately 10g makes this micro metal gear motor ideal for small mobile robots where payload capacity and power efficiency are limited. The compact gearbox and slim motor body allow installation in narrow chassis spaces while still providing meaningful torque output up to 250g·cm under load. Such characteristics make the drive unit practical for compact robot cars, educational prototypes, and embedded mechanical motion systems.
