Evolution and Modern Approaches for Thermal Analysis of Electrical Machines

Abstract: In this paper, the authors present an extended survey on the evolution and the modern approaches in the thermal analysis of electrical machines. The improvements and the new techniques proposed in the last decade are analyzed in depth and compared in order to highlight the qualities and defects of each. In particular, thermal analysis based on lumped-parameter thermal network, finite-element analysis, and computational fluid dynamics are considered in this paper. In addition, an overview of the problems linked… Show more

“…To further investigate the thermal behavior of the proposed winding, 2D FE thermal analysis is carried out to predict the temperature distribution in the slot under both healthy and faulty operation. The study is carried out in a coupled electromagnetic and thermal FE simulation environment [42,43]. The same FT-PMSM is used in this analysis, where the cross section area, insulation thickness, slot coating, slot dimensions and thermal boundaries (stator outer surface temperature is fixed to120 °C) are kept the same for both windings.…”
