Experimental and numerical analysis of lift force in magnetic levitation system

A new type of magnetic levitation system using the shielding effect of the HTS bulk is studied. The system includes a permanent magnet and three HTS bulks as a vehicle, and a ferromagnetic bar as a guide way. The simple structure of the guide way reduces large amount of construction costs. The system also provides stable lift force without any active control system. The characteristics of lift force are numerically analyzed using IEM(Integral Element Method). Experiment was performed using a small model. The two results are compared.
