转子轭部磁密高了太多了   和上科所Y2的差了太多了

怎么都没人回答啊    自己顶下

回复 2# 郑海


     看看转子轭部的相关尺寸如何。是否与上科所输入的尺寸有差异。

郑海

槽型和端部面积等 其他的参数都是一样的   计算结果轭部磁密严重饱和  都2D磁力线都是从槽中过

楼主，问题解决没有？

我也遇到同样的问题了{:soso_e117:}

Coil Pitch:        0

兄台  我用maxwll16 路算三相异步电机的时候 上面好像没有地方填coil pitch数据  是我没有找到的原因吗  我看计算单的时候 coil pitch为0，所以特来问问大侠的，所以在这里请教一下啊

拉风的星星

楼主 你先将所有英文参数理解了，之后再理解各个参数代表的实际意义。看了下，很多参数都不对
