Magnetic Field Analysis of Axial-radial Flux Type Fully Superconducting Synchronous Motor
摘要
Abstract
In order to simplify the cooling system of conventional superconducting motor, a novel axial-radial flux type fully superconducting synchronous motor (ARFTFSSM) was proposed, and its configuration characteristics and operation principle were discussed. The non-load magnetic field of ARFTFSSM was calculated by using 3D finite element method (FEM), and the magnetic fields of high temperature superconducting (HTS) synchronous motor with different axial magnetic motive forces (MMF) were analyzed, from which the influence of axial flux on radial flux distribution was studied. Meanwhile, the results were verified by non-load back-EMF experiments on prototype. Based on the structure of the prototype, a new kind of rotor structure was proposed. The air-gap magnetic fields in HTS motors with these two different rotors were comparatively analyzed, especially for the harmonic contents of air-gap flux density. Some useful conclusions were obtained, which could be beneficial to the further study on optimizing design and performance characteristic analysis of the large capacity ARFTFSSM.关键词
