- Magnetic interaction rotates the rotor at very high speed
- Attached propellers generate airflow and thrust for flight
The coreless structure reduces inertia, allowing:
- Faster acceleration
- Better efficiency
- Improved throttle response
Applications
- Mini drones and quadcopters
- Nano UAV systems
- RC airplanes and gliders
- Toy helicopters
- DIY aerial robotics projects
- Small propeller-based experiments
