Calculation of the magnetic bearing with HTS elements for flywheel energy storage system

Abstract

Calculation of magnetic systems with elements of bulk high-temperature superconductor is a complex problem because of the need to consider the influence of non-linear, hysteretic and anisotropic electrophysical properties of superconducting materials. Existing mathematical models or not fully describe the properties of superconductors, or convenient for use with discrete modeling techniques. The paper presents the method of a numerical calculation of three-dimensional magnetic systems with HTS elements developed by the authors. The method is based on the resistive model of properties of HTS and on the integral equations of the electromagnetic field. The results of calculations of the magnetic bearing for flywheel energy storage are presented and compared with experimental data.Keywords-high-temperature superconducting (HTS) material; model of the electrophysical properties; magnetic system with HTS elements; method of calculation; magnetic bearing based on HTS.
