开关磁阻电机静特性的有限元分析

Finite-Element Analysis of Static Characteristics of Switched Reluctance Motors

本文利用二维有限元法对开关磁阻电机的静特性(即磁链特性、电感特性和矩角特性)以及相与相之间的互感进行了详细的计算和分析。在分析中考虑了端部效应的影响,测量了一台试验样机的电感曲线,所得结果与计算结果很吻合,这表明应用有限元法对开关磁阻电机进行分析是足够准确、有效的。

In this paper, the static characteristics of switched reluctance motors (SRM) are analysed in detail. The flux-linkages, inductances and torques as well as mutual inductances with different currents and rotor positions are calculated by using two-dimensional finite-element analysis(FEA). For getting more accurate results, the effects of the fringe flux of ends are considered. A prototype SRM has been made. The comparison between the experimental results and computed results of the prototype motor shows that FEA is sufficiently accurate to analyse the static charateristics of SRM.
