Stabilization of non-controlled magnetic levitation motor utilizing the diamagnetic magnetic force of PG disk and rotating torque measurement

Abstract

　It can be widely applied if it can stably levitate and rotate the floating rotor without using automatic control or superconducting material. The diamagnetic magnetic force generated by diamagnetic substances is very small. The author found that a heavy floating rotor can be levitated by a combination of magnetic force between floating rotor magnet and radially arranged permanent magnets, and diamagnetic magnetic force between fixed magnet group and PG disk. In this paper, I will explain how to levitate the floating rotor. In addition, I show the calculation method necessary for levitation analysis and describe the usefulness of surface current method used for analysis.
