反磁性ビスマスを利用した無制御磁気浮上モーターの試作

抄録

Using the diamagnetic magnetic force of bismuth, the author succeeded in magnetic levitation in a non-controlled and non-rotating stationary state. Furthermore, by applying a rotating mechanism, it became possible to work as a non-controlled magnetic levitation motor. The author examined the placement of the permanent magnet that can float by experiment and numerical calculation and found the optimum combination of permanent magnet and diamagnetic material.
