Calculation of magnetic suspension based on high-temperature superconductors for kinetic energy storage

The paper presents a mathematical model, the results of computational and theoretical research, and the feasibility of creating a vibration converter with full magnetic levitation in the suspension of a high temper ature superconductor (HTSC). The axial and radial stability of the active part of the converter is provided by the interaction of the magnetic field of ring shaped permanent magnets and a hollow cylinder made of the ceramic HTSC material. The force is created by a system of current carrying coils whose magnetic field is polarized by permanent magnets and interacts with induced currents in the superconducting cylinder. The case of transition to the superconducting state of HTSC material in the field of the permanent magnets (FC mode) is considered. The data confirm the outlook for the proposed technical solutions.

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.
