Multi-Physical Model for Sizing Optimization of Electrical Machines

International audienceThis paper presents a layered multi-physical model for sizing optimization as well as solving a specific optimization problem of interior permanent-magnet (PM) synchronous machine (IPMSM) for traction application. The advantages of the model structure are the management of the calculation time and the multi-physical aspect taking into consideration the iron losses and the thermal phenomena. An analysis is conducted over an optimization problem with different nested loops and for several operating points of the IPMSM
