816 Coreless DC Motor 3.7V High Speed 55000RPM

816 Mini Coreless DC Motor 55000RPM for RC Drone and Robotics

The 816 Coreless DC Motor is a compact, lightweight, and high-speed motor designed for RC aircraft, quadcopters, micro air vehicles, and DIY electronics projects. Operating at 3.7V DC, this miniature motor can achieve a no-load speed of approximately 55000 RPM, making it an excellent choice for applications that require fast response and efficient performance.

Unlike conventional brushed motors with iron cores, a coreless motor features a lightweight rotor design that reduces inertia and allows faster acceleration, smoother operation, and improved efficiency. The 816 motor utilizes strong Nd-Fe-B permanent magnets, precious metal brushes, and high-temperature Teflon leads to ensure stable operation in demanding applications.

This motor is widely used in small RC drones, fixed-wing aircraft, educational robotics projects, and STEM learning activities. Students, hobbyists, and makers across Bangladesh frequently choose this compact motor for science fair projects and custom drone development. At Biggan Project, we provide electronic and robotics components suitable for students, hobbyists, and innovators throughout BD. Whether you are building a mini drone, micro robot, or experimental flying platform in Bangladesh, the 816 Coreless Motor offers an efficient and practical solution.
