Finite Element Analysis of Electrical Machines: Recent Trends and Developments

Finite element (FE) method, is the most popular numerical approach to low-frequency electromagnetic modeling, especially in the field of electrical machines. Although FE method is nowadays widely used by experts, still it can find widespread efforts toward additional developments that make it more applicable to various problems. This paper takes a look at the state of the arts in the electromagnetic modeling of electrical machines via FE analysis. The addressed subjects cover new techniques for loss calculation in electrical machines, the state of art toward more efficient computation, which is a serious challenge for numerical methods, and modeling efforts for the hysteresis phenomenon. The paper tries to address a portion of the recent hot topics of FE analysis of electrical machines. The authors believe that the paper will give a brief but useful insight into the challenges and developments of FE applications in electrical machine analysis, as the most practical numerical tool in this area.
