Introduction
DFRobot Coreless Micro Motor (7×20mm) provides a compact propulsion solution for lightweight aerial builds and small robotic mechanisms. This high‑speed brushed coreless motor operates efficiently at a rated voltage of 3.7V while delivering rotational speeds up to 50,000rpm. The ultra‑small cylindrical structure allows easy integration into micro drone frames, compact RC aircraft, and experimental flying platforms where weight and space are critical design constraints. A 1mm shaft and slim 7mm diameter profile simplify propeller mounting and mechanical alignment, making this miniature high‑RPM drive unit well suited for DIY quadcopters, educational robotics experiments, and other compact motion projects.
High-Speed Performance in a Micro Form Factor
This 7×20mm coreless motor combines extremely small dimensions with impressive rotational performance. Despite its compact body, the micro propulsion unit reaches speeds up to 50,000rpm at rated voltage, enabling strong thrust generation when paired with lightweight propellers. The efficient brushed coreless design minimizes internal losses and allows rapid acceleration, making the miniature drive motor suitable for micro quadcopters, palm‑size flying machines, and other airborne DIY platforms requiring responsive and lightweight power sources.
Optimized for Lightweight DIY Drone Projects
A slim cylindrical housing, low operating voltage, and simple two‑wire connection make this miniature DC motor particularly convenient for hobbyists and prototype developers. The compact shaft design supports easy propeller installation, while the small footprint helps reduce total aircraft mass in micro aerial builds. This compact rotary actuator also fits well into experimental robotics, micro vehicles, and small mechanical assemblies where compact high‑speed motion components are required.
Typical applications include DIY micro quadcopters, lightweight RC drone prototypes, miniature robotics platforms, educational engineering builds, and other small electromechanical projects that require compact high‑RPM motion components.
