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。 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:} 槽型代号是不一样的，你再仔细看看 Slot Fill Factor (%): 223.799
Coil Pitch: 0
转子槽自定义尺寸估计有问题 看看转子轭部的相关尺寸如何 Slot Fill Factor (%): 223.799
怎么都不行 2519743009 发表于 2014-10-20 15:48
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 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
