好好看看了  学习一下吧

edm3000

LZ真强啊，受教了。

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

真的很不错。

taner2066

非常好的教材

yzhangx

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.

sweer616

我要好好学习

flytogod2

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

反复看帖 要学会为止 感谢大家的分享

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

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！
