4PCS Coreless Micro Motor (8*16mm)

Coreless Micro Motor (8×16mm) is a compact high‑speed actuator designed for lightweight DIY drone and robotics builds. Operating efficiently at a rated voltage of 3.7V, this miniature brushed motor delivers impressive rotational performance reaching up to 50,000rpm despite an ultra‑small footprint. The 8mm diameter cylindrical structure allows easy installation in micro airframes and compact mechanical assemblies, while the simplified wiring design helps accelerate prototyping. Paired with small propellers, this high‑speed micro drive solution provides strong thrust generation for experimental quadcopters, miniature aircraft platforms, and other small motion systems.

High-Speed Performance in a Micro Form Factor

An 8×16mm cylindrical body houses a powerful coreless drive structure capable of reaching speeds up to 50,000rpm. The coreless architecture minimizes internal inertia and improves responsiveness compared with traditional iron‑core motors, enabling rapid acceleration and efficient power conversion. Such characteristics make this micro propulsion component highly suitable for small aerial platforms where high thrust‑to‑weight ratios and fast motor response are essential.

Optimized for 3.7V Lithium Power Systems

Rated operation at 3.7V aligns perfectly with common single‑cell lithium batteries widely used in micro drones and portable robotics projects. Stable performance at this voltage simplifies integration into lightweight flight controllers and compact electronics assemblies. The moderate rated current of 170mA supports efficient energy usage while still delivering strong rotational output for propeller‑driven lift systems.

Compact Structure for Easy DIY Integration

An ultra‑small 8mm diameter body and 16mm motor length enable installation inside tight drone frames or miniature mechanical housings. The 0.8mm shaft with 5mm length supports small propellers and lightweight rotating components, making this compact actuator suitable for experimental robotics, miniature propulsion mechanisms, and educational prototyping projects requiring reliable micro‑scale motion.

Typical applications include DIY remote‑control drones, micro quadcopters, lightweight robotic mechanisms, experimental propulsion systems, and educational engineering projects exploring miniature high‑speed motor control.
