基于Ansoft的永磁无刷直流电动机磁场有限元分析

Magnetic Field Finite Element Analysis of Permanent Magnet Brushless DC Motors Based on Ansoft

基于有限元分析软件Ansoft,采用全场域二维磁场有限元分析方法;对永磁无刷直流电动机的磁场分布等进行了计算。这些工作为分析永磁无刷直流电动机的工作原理及永磁无刷直流电动机的进一步开发和应用,建立永磁无刷直流电动机合理的非线性模型提供了理论基础和可靠依据。

2D whole field finite element method（FEM）based on Ansoft software was adapted,and the magnetic field distribution of permanent-magnet brushless DC motor（BLDC）were calculated.The above discussion can provide reliable theory foundation for the reasonable establishment of nonlinear model BLDCM and the further exploitation and application.
