Exploration of a floating magnet rotor in diamagnetic levitation system

This paper presents a floating magnet rotor with a toothed shape in diamagnetic levitation system. The floating rotor is levitated between two pyrolytic graphite sheets to allow for friction-free rotation. The rotor has a special shape with three notches which are evenly distributed on circle direction. The revolution of the rotor is demonstrated by applying a pulsing airflow with a mechatronics cylinder, showing pulse actuation with the minimum speed of 8 r/min. The promising results suggest potential applications of the mechanism toward frictionless sensors and actuators
