The presentation will cover recent developments in design techniques, which are based on detailed multi-physics modeling of electric machines and power electronics operation under duty/drive cycles, and are suitable for large-scale high performance computing (HPC) systems. New computational artificial intelligence optimization methods based on a combination of Differential Evolution (DE), Design of Experiments (DOE) and Kringing Surrogate (KS) techniques and employing thousands of candidate designs evaluated with 2D FEA, or variations based on a reduced set of 3D FEA models, will be discussed. Practical examples will include machines and drives for the latest generation of electric vehicles (EV), first generation formula-E racing cars, multi-MW power trains for electric and hybrid airplanes, high-speed solar cars and high-altitude solar airplanes. The combined role of coupled electromagnetic, thermal and fluid dynamics analysis will be exemplified on an induction motor developed for the latest generation of a luxury EV. The talk will conclude with a brief presentation of the recent book authored by ANSYS experts and collaborators “Multiphysics Simulation by Design for Electrical Machines, Power Electronics and Drives” published by Wiley – IEEE Press.
