这个翻译错了吧

请zengxiaodong老师看一看:
Calculation>>Drive Type>>有2个选项,它们有什么区别?

应该是类似于电流激励、电压激励吧。


指定电流,应该就是对应于电流激励。

计算电流,应该就是根据电压迭代出电流,然后用该电流来驱动。

以上仅是个人理解,供参考。

新版还有了结构分析功能,真的是可以集电机设计计算之大成了,软件小巧,运行快速,结果精准,还是中文版的 ...

新版本优化进步很多,感觉很好用

感应电机试用了一下,还在摸索中。

感觉转子槽形设置不太方便。

感应电机饱和模型,用有限元法有问题,计算结果不靠谱,而用解析法还算靠谱。

学习了,多年前用过motorCAD的热模块,最近在看他的电磁模块。

期待新版本,结构功能以及噪声分析功能方面可能会有大幅度提高!

楼主:
用Motor-CAD电磁模块计算时,机械摩擦和风摩损耗,在哪里输入?

电磁模块计算时,机械摩擦和风摩损耗无法输入,要在热模块输入

下载了,走马观花看了看,对于初学者帮助很大,慢慢研究中,

是的,当前Motor-CAD主要还是二维计算,采用很多等效方法,去求解一些三维问题,但是后续 轴向电机模块 ...

现在MOTOR-CAD中有轴向电机模块了吗?有这方面的实际需求

ANSYS_Motor-CAD_15.1.2_Fixed




补充内容 (2022-12-3 17:46):
把提供替换的文件netapi32.dll额外拷贝一份到ANSYS_Motor-CAD\15_1_2\licensingclient\winx64目录里面就可以了!

The Campbell diagram shows the magnitude spectrum at variable speed operation of the main excitation orders. Excitation frequency order lines are displayed for frequency orders going from one up to the maximum value defined from the Nyquist Shannon Theorem.

Multiple frequency order lines are possible for a given order “n”, e.g. (m = 4, n) and (m=8, n). The Plot Selection dropdown allows to track frequency order lines considering either all wavenumbers or a particular wavenumber. By hovering the mouse cursor on an excitation order line, the space and frequency orders along with the speed and frequency data are displayed in the status line. Operating points at which force harmonics are calculated are defined in the Calculation tab. Harmonic force data are then interpolated between simulated speed points.

The dark blue regions correspond to either regions of null excitation in between two consecutive frequency order lines, or regions where the excitation is simply not calculated, as per the Nyquist-Shannon Theorem. Dashed lines represent the natural frequencies of the stator structural modes, calculated from the Modal analysis.

The Campbell Diagram represents the force excitation frequencies of the stator against various operating speeds. Each frequency/space orders colour is displayed relative to it's maximum amplitude across each load point. Dashed vertical lines represent the natural frequencies calculated from the Modal model up to the maximum plotted excitation frequency. See NVH settings for more information on the maximum plotted excitation frequency.

This plot is extremely useful to not only extract the main excitation orders but also evaluate their potential interaction with the stator structure (see Resonance Effect for more information).
