Steady state heat conduction problems of AFPMSM using 3D Finite Element

Abstract

It is important to study the thermal performance of electric machines which depends on many variables, one of them is the motor speed. In this paper, the effect of changing the speed is studied, with maintaining the other parameters, by analyzing a 3D thermal model of an axial flux permanent magnet synchronous motor (AFPMSM) and solving steady state heat conduction equations with finite elements (FE). Comparison between the resulted temperature values of the motor at each part due to various rotor speeds is performed.
