Abstract

A magnetic levitation system using magnetic shielding effect of HTS bulk is studied. The system is constructed by permanent magnets, zero-field-cooled superconducting bulks and ferromagnetic rails, and lift force stability is obtained from magnetic field that is generated by the permanent magnet and is shaped by the superconducting bulks. In previous studies, we showed characteristics of lift force and stability about a basic model which had a small ferrite permanent magnet, three YBCO bulk superconductors and a short ferromagnetic bar. Now, improving the basic model, we found new models which have better characteristics of lift force by numerical analysis using 3D Integral Element Method (IEM). The new models are reported
