4PCS Coreless Micro Motor (4*12mm)

4×12mm Coreless Micro Motor is a compact high‑speed drive solution designed for lightweight aerial robotics and miniature mechanical builds. Operating at a rated voltage of 3.7V, this ultra‑small brushed DC motor delivers impressive rotational performance reaching up to 60,000rpm while maintaining minimal current consumption. The micro‑scale cylindrical form factor allows seamless integration into palm‑sized drones, micro robotics, and precision motion systems. A 0.7mm output shaft supports small propellers and gear mechanisms, enabling efficient thrust generation for DIY quadcopters and experimental flying platforms where weight, speed, and simplicity are critical design factors.

Ultra‑Compact High‑Speed Drive

The miniature 4×12mm cylindrical structure combines a lightweight coreless design with extremely high rotational speed. Achieving up to 60,000rpm under rated conditions, this micro power unit produces strong thrust when paired with small propellers. The reduced mass and minimal inertia improve acceleration response, making the motor highly suitable for micro aerial vehicles and compact motion mechanisms that demand rapid speed changes and efficient propulsion.

Low Voltage Operation for Lightweight Systems

Rated for 3.7V operation and drawing approximately 40mA under normal conditions, this miniature propulsion component works efficiently with common single‑cell lithium batteries used in small drones and portable electronics. Low voltage requirements simplify power system design while helping maintain lightweight builds. Such electrical characteristics make the motor ideal for battery‑powered robotics, experimental flying devices, and compact motion projects.

Designed for DIY Drone and Micro Robotics Projects

A 0.7mm diameter shaft with 4mm length supports common micro propellers and small mechanical couplers, enabling easy integration into DIY drone frames and tiny robotic assemblies. The compact dimensions allow multiple motors to be installed in tight layouts such as quadcopter frames or miniature propulsion systems. Reliable high‑speed output and simple wiring make this coreless micro drive a practical choice for hobby prototypes and experimental robotics.

Ideal for lightweight drone propulsion, micro robotics mechanisms, and compact motion experiments, this miniature high‑speed motor supports creative engineering projects where size and power density matter. Small aerial vehicles, DIY quadcopters, educational robotics builds, and precision miniature devices benefit from the combination of compact dimensions, efficient power usage, and high rotational speed.
