Abstract

this paper proposes an effective design process for matching axial length between stator and rotor of high temperature superconducting synchronous motor (HTSSM) using two-dimension (2D) finite element method (FEM), magnetic network method (MNM) and three-dimension (3D) finite element method. During this process, 2D FEM is used to get distributional parameter in short time by selecting some representative 2D plane in 3D geometrical space. MNM are more efficient and faster, which is build after accepting some useful conclusion by 2D FEM. 3D FEM is used to makes necessary adjustment, and the result also verify the validity of the former methods, because of its accuracy. The design process is performed in the 1MW HTSSM design for search proper axial length of stator and rotor. The results provide strong direction in different design period, which verify the validity of the method.
