Séminaire Equipe OMN, 2 Juillet 2018

Le lundi 2 juillet 2018, Pr. Anouar Belahcen (Aalto University), effectuera un séminaire sur le thème :

Research at Aalto University, with an emphasis on the magneto-mechanical coupling

Date : Lundi 2 juillet 2018 à 13h30
Lieu : Salle 2S53 à Lilliad

The first part of the presentation introduces some of the research subjects at Aalto University, Department of Electrical Engineering and Automation. The second part focuses on the research related to the magnetomechanical coupling in electrical steel. Here a measurement setup for rotational magnetic field and arbitrary mechanical stress will be presented together with the results of measurements on a non-oriented electrical sheet. Further, a model for the magnetomechanical coupling will be presented and discussed. The magnetic properties of electrical steel sheets are known to be highly stress dependent. During the manufacturing processes and operation of these devices, multi-axial stresses are exerted on the core laminations. The performance of the electrical machines is then significantly affected by these multi-axial loadings. In order to be able to design efficient devices and analyze the existing ones with better accuracy, the dependency of the core losses on the multi-axial stresses should be studied comprehensively. Yet another important issue is the effect of these loading on the noise and vibrations of electrical machines.
