Method Analysis

A superconducting magnetic levitation system, with permanent magnet guideway and bulk superconductors, can realize a more advantageous system for transportation. The calculations of electromagnetic force characteristics are presented using finite element method analysis. The hysteretic behavior of the forces has been reproduced assuming a critical state model for the superconductor, and the results of the analysis are compared with the experimental data. Prom these results we have confirmed that the three-dimensional structure of magnetic field and the electromagnetic performance of superconductors strongly influence the characteristic of the electromagnetic force. Furthermore, a new hybrid superconducting magnetic levitation system has been designed to optimize the electromagnetic force.
