摘要

磁链特性的准确计算是无轴承开关磁阻电机设计和控制的基础。本文采用三维有限元法对BSRM主绕组和悬浮绕组的磁链进行了计算。提出了一种新的分区域拟合算法，并利用傅里叶级数和Levenberg-Marquardt(LM)优化方法建立了新的磁链数学模型。基于新模型，得到了增量电感、反电动势因子和瞬时转矩。这将为BSRM的分析、设计和控制提供重要的理论依据。

A new flux-linkage model for bearingless switched reluctance motor

Accurate calculation of the flux linkage characteristics is the basis of design and control of bearingless switched reluctance motor (BSRM). In this paper, flux linkage of main-and suspended windings for a BSRM were calculated by using 3D finite element method (FEM). A new subregional fitting algorithm was proposed and a novel mathematical model of flux linkage was built by using fourier series and Levenberg-Marquardt(LM) optimization method. Based on the new model, the incremental inductance, back-emf factor and instantaneous torque were obtained. This will provide important theoretical basis for the analysis, design and control of the BSRM.
