Loss Model Impact on Multi-Physical Coupling Designed for Sizing Optimization of Electrical Machines

Abstract

This article analyzes and highlights the impact of an iron loss model on temperature estimation within a multiphysical model of a radial-flux permanent-magnet (PM) synchronous machine (PMSM) for traction application. Three iron loss models have been compared in terms of computing time and accuracy within the machine torque-speed plane. This study underlines the iron loss calculation impact on the temperature estimation in the PMSM in relation with the required performances.
