In this paper, a multi-physic approach allowing the accurate analysis of electrical machines is presented. This original approach exploits a generalized nonlinear adaptive magnetic equivalent circuit (MEC), a dynamic hysteresis model and an aerothermal model. The model coupling has been applied to a radial-flux interior permanent-magnet synchronous machine (PMSM) dedicated to automotive applications. The influence of the MEC discretization on the iron loss calculation and the electromagnetic and thermal performances of the machine has been analyzed.
