摘要:
采用通用有限元软件对永磁同步电动机电磁场分析时,存在着电动机定、转子轴线相对位置未知的问题,而确定这个相对位置是任意负载下磁场计算的前提.本文通过研究电动机电磁量之间的关系找到特定内功率因数角下气隙合成电势和内功率角的特征.提出一种相当于逆问题分析的处理方法,在不同定子电流初相位下进行计算,搜寻对应于特定内功率因数角磁场分布,从而求得定转子空间的初始相对位置.
Abstract:
When designing universal finite element software for analyzing the permanent magnet synchronous motors(PMSMs), the relative position of the stator and rotor axis remains unknown. However determining the relative position is a precondition for electromagnetic field calculation. Through analyzing the basic relationship of variables in synchronous machines the characteristics of air gap resultant EMF and inner power angle under special inner power factor angle can be obtained. A technique similar to inverse problem solving is proposed in this paper. A series of electromagnetic field calculation under different armature current initial phase angles are carried out firstly, then through searching the field of special inner power factor angles the relative position of rotor and stator can be determined subsequently.
