电励磁同步电机电磁计算单问题

电磁计算单中的损耗为什么为负

Delcev 发表于 2021-3-8 18:54

your efficiency is not correct [-359%]. And the phase voltage is 400 V? should it be 230 V?

参数输入错误，请核对一下

谢谢 将相电压改为230后 但是 Field copper loss(磁场铜损？） exciter loss(励磁机损耗） 还是为负 这是为什么呢 ？

嗯呢 也不太懂是哪个参数出问题啦 = =

It has to do something to Exciting current density (A/mm^2) and Excitation voltage (V), they should not be negative.

励磁电密和励磁电压 和什么参数有关呢yc_face65在RMxprt哪里设置呀

Can you sent the model to check it?
