Ansoft 12 稳态电磁场求解的例子,说BH有问题,没发现啊
Solving for Magnetostatic adaptive pass 1, process solver2d: Internal Solver Warning:'In the Material: DW465-50 , the SLOPE of the End Two Points in this BH curve is 24.4349, which is more than 2 times of Mu0; This may lead to a non-physical solution. Please check the BH curve!' (9:38:22 AMNov 14, 2018) Ansoft 12 第四章, 永磁同步电机静磁场分析实例,我计算出来的结果和光盘里的结果有些出入,我得到的Force是Mag 10.261,书中的结果是29.281,还有磁力线分布也有些差异,请大神指点迷津 ansoft 程序(个人按照书中的例子所做)

这个问题我也遇到了,楼主解决了吗?
这个是ansoft新版本新增加的功能,就是检查磁化曲线高饱和段的斜率,软件要求磁化曲线斜率也就是磁导率应该大于1小于2.如果超过2,就会报上述警告
电机如果不是太饱和,该警告可以忽略,对电机性能影响很小 谢谢楼主 学习了 确实如forlink说的,其实只是一个警告,不是错误报警,不影响计算结果 你好,不知道仿真结果有没有遇到力force非常小的情况,按照课本模型修改了之后,磁力线和磁通基本吻合,就是力一直对不上,不知道是否有人遇到相同情况
下载参考一下,自己做也是好多的疑惑
