摘　　要：介绍一种电机二维磁场有限元自动网格剖分方法。该方法能适用于电机多媒质和媒质交界线曲折多变的情况 ,特别是能满足带周期性条件的磁场区域的自动网格剖分要求。磁场区域首先划分成若干子域 ,子域形状允许是带凹角的曲边多边形。子域网格剖分时 ,通过设置子域轮廓线上的节点数和节点间距的几何级差 。A method of automatic mesh discretion for two dimensional magnetic field is presented in this paper.The method is suitable for multiple mediums and the flexuous medium boundaries.Especially it satisfies the need in discretion automatic mesh for magnetic field with periodic conditions.First,the whole magnetic field domain is divided into several sub domains,which permit of concave polygons.Then,mesh distribution in desirable densities is realized by setting the numbers on sub domains contours and the node spacing geometric at series of differences.
