The so-called ring-shape superconducting trapped field magnet has great potential for commercial application due to its flexible size and joint-less structure. However, the spatial asymmetry of structure, magnetic a non-negligible declination, which becomes major obstacle application. To compensate new concept hybrid consisting HTS bulk is proposed. By adjusting placement in central air gap, declination can be effectively compensated. Both experiments 3D numerical model are used evaluate...
The ring-shaped superconducting permanent magnet, with its great advantages in flexible sizing and trapped field, has become a potential candidate for portable medical applications. However, due to the complex geometry involved, it is difficult predict electromagnetic performance by traditional numerical methods. This paper presents field-circuit coupling method study entire magnetization process of magnet. Firstly, principle introduced proved be sufficient magnet large turn number. Then,...
The so-called ring-shape superconducting trapped field magnet has been proved as a potential candidate to replace commercial permanent magnets in practical industrial applications on account of its jointless structure. In this paper, circuit method based Bean model, E-J power law and Faraday built investigate the magnetization mechanism magnet. dependent critical current materials taken into consideration for further optimization. numerical model was verified by both finite element (FEM)...
