Coupled Numerical Field Computation in the Multi-Physics and System Analysis of Electrical Machines

Welcome to a seminar arranged by the Electromagnetics Laboratory (abbreviated EM-Lab), which is an assembly of senior researchers and teachers with activities in the scientific field of electromagnetics. EM-Lab is hosted by the Department of Electrical Engineering at Chalmers.
Speaker:  
Áron Szűcs, Principal R&D Engineer in ABB Motors and Generators, Technology Center, Helsinki, Finland 
Associate Professor at the University of Pécs, Hungary

Title:
Coupled Numerical Field Computation in the Multi-Physics and System Analysis of Electrical Machines:
with examples from drive system analysis to experimental diamond based insulation.

Abstract: 
The basic theory of electrical machine design is more than 100 years old, but there are continuous significant developments in the field of material science, manufacturing technology and computation methods. Similarly while the numerical electromagnetic field computation of electrical machines has several decades of history, new technical demands and industrial competition has led to the rise of new perspectives in computation methods. These include the more comprehensive views of electrical machine design involving multi-physics and system analysis.
The lecture reviews the numerical coupling / interfacing techniques for, and the similarities and differences in Multi-physics and System analysis. The example cases will range from drive system analysis, through traditional electromagnetic-thermal coupling, to issues with experimental diamond based insulation systems. 
Finally future development directions and upcoming research topics will be discussed, to encourage academic research in the directions of uncertainty quantification and efficient digital twin model development.

Biography: 
Áron Szűcs is a Principal R&D Engineer in ABB Motors and Generators, Technology Center, Helsinki, Finland and an Associate Professor at the University of Pécs, Hungary. He graduated as an electrical engineer MSc. from the Technical University of Budapest in 1995. He wrote his MSc thesis at the Helsinki University of Technology from where he later got his PhD (D.Sc. Tech) in 2002. He works and publishes on the field of advanced design and simulation methods for the electromagnetic modeling of electrical machines, design optimization of electrical machines, e.g.: Induction machines and wind generators. Next to his academic publications he holds several patents on the field of electrical machines. He has been active in international scientific and industrial societies including Compumag, EPNC, Cigre, etc. Lately he developed an obsession with diamonds, but not because they are forever, but because they are the best solid thermal conductors and excellent electrical insulators. More about that in the presentation... He firmly believes that efficient and successful work in either industrial or academic research and technology development must entail a close cooperation between these worlds.
