Finite element analysis of rotating electrical machines — An educational approach

The paper presents the application of the Finite element method in teaching the fundamental theoretical aspects of rotating electrical machines to undergraduate students. The scope of the paper is to highlight the fundamental principles of electromagnetic field computation and analysis using two dimensional Finite element method. This is suitable for teaching students at undergraduate level, as the problem formulation is based on the direct integration of Maxwell's equations for firstorder elements, avoiding the use of a complex mathematical treatment. The preparation of a model of the machine and analysis of the obtained results are presented in a simplified manner in order to be more affordable to students. The throughout explanation is supported by various results, that students can directly obtain, observe and analyze, using Finite element analysis. The application of the Finite element method for modeling makes it possible to explain and discuss the behavior of rotating electrical machines for healthy and faulty conditions.
