摘要
For the coupled electromagnetic and structure-dynamic simulation of electrical machines, various 2-D and 3-D techniques are available. This paper reviews and compares them. The strength as well as the weaknesses of these methods are pointed out. Numerical results for the analysis of a switched reluctance machine (SRM) as an example evaluate accuracy and computational effort. It shows that the 2-D simulation gives quite accurate results, as long as the axial effects and 3-D mode shapes are not relevant.
