双定子永磁无刷电机电感特性分析

Inductance Characteristic Analysis of Double Stator Permanent Magnet Brushless Machine

基于二维有限元法研究了双定子永磁无刷电机(DS-PMBL)内外定子绕组的电感特性,提出了一种计算DS-PMBL电机不饱和电感与饱和电感的数值计算方法,得出了DS-PMBL电机电枢绕组饱和电感的变化规律。对一台现有DS-PMBL样机电枢绕组的饱和电感进行了测定,实验结果验证了有限元计算与理论分析的正确性。

This paper investigated the inductance characteristic of the double stator permanent magnet brushless（DS-PMBL） machine by using two dimensions finite element analysis（FEA）,proposed a new numeric calculation method to calculate both unsaturated inductance and saturated inductance of the DS-PMBL motor,and derived the variation tendency of the armature winding inductance.Experimental results verify the FEA and the theoretical analysis by measuring the armature winding inductance of an existing DS-PMBL motor.
