Prof. Abdelkader Benabou
Abdelkader Benabou graduated in material sciences in 1999 and received his Ph.D. degree in electrical engineering in 2002 from the University of Lille in France for research related to the modelling of magnetic hysteresis. After 2 years of post-doctoral position, in 2004 he was nominated Associate Professor in electrical engineering at University of Lille where he continued his research on the magnetic materials within the context of energy conversion devices. Since 2023, he is Full Professor at University of Lille. His current research activities are mainly focused on the characterization and modelling of magnetic materials while accounting for the impact of the manufacturing processes and electrical machine operating conditions on their properties.
Presentation: Some considerations on the evolution of the usage properties of magnetic materials for energy conversion devices: an overview of magnetic aging
Ferromagnetic materials are one of the key elements in the performance and energy efficiency of energy conversion devices, as in modern industrial applications and electric mobility. Precise consideration of the behaviour of these materials within these devices is necessary from the design phase, but also during their operation, particularly in a digital twin context. The presentation will focus on the irreversible effects of temperature on the magnetic properties of electrical steels. Experimental characterisation of this so-called magnetic ageing effect and an initial modelling approach of the iron loss evolution with ageing time will be presented.
