Using of HTS tape coils for the design of a magnetic bearing

Abstract

The use of HTS materials for the construction of magnetic bearings has shown their high efficiency. Currently, more and more research is focused on the use of tape superconductors for magnetic bearings. Application of HTS tapes allows simplifying the manufacturing technology of these devices and improving the specific power characteristics. However, when modelling devices with HTS tapes, computational difficulties arise due to the small thickness of the active layer. The paper considers the possibility of using models for magnetization to describe the properties of HTS tapes in the calculation method based on the integral equations of an electromagnetic field. The features of the proposed models are illustrated by the results of solving simple test tasks and calculations of real designs of magnetic bearings. To confirm the correctness of the simulation, the calculation data are compared with the data of experimental studies.
