用楼主给的参数检验了一遍,为什么我算出来的参数同楼主的有些不一样呢,我用的硅钢片是DW465-50

使用时间不长,用在计算电阻启动电机,额定还是比较准,比浙江大学的EMCAD还要好,启动,堵转不准.
我用过好多的程序,正版,感到这个程序还可以的.应该打8分.

这个程序本身算出来的 好像和实际有很多差距!这需要具体根据实际情况调整啦!我们单相和三相都用的是上科所的。

不管用什么软件,都只是一个工具而已,完全靠软件就不需要那么多做开发的设计人员了,主要是在工作中多积累经验和数据。

结果不是重要的,对于初学者主要是过程,如何分析电机出现的异常的曲线如何分析判断

你是在人家的基础上计算的,结果自然是更接近,如国楼主贴一个假的实际结果,我想你也估计要向假结果靠近了{:1_431:}

我这里刚刚有一个电机,后天排到测功机上测试!大后天出结果。你帮我算算,参数如下:
参数、槽形可能不是很合理,原因是这个电机是手工嵌线,现在人工难招,我就把槽形凑近到自动下线机上,因此就有点牵强!不过没关系,只要温升通过,我就能出货!{:aa13

从你的结果来看,你的叠高可以再减一点,槽满率才40多,热负荷也不高、
