- Increasing the efficiency of rotating electrical machines and transformers by using new materials, very thin electrical steel laminations for example, or by equipping additional devices which brings significant efficiency gains.
- Developing electrical machines monitoring methods, in industrial sites. We aim at detecting faults with non-invasive methods, as eccentricity or turn to turn short-circuits and at predicting the machines aging in order to avoid heavy failure. The works also consist in determining, always with non-intrusive methods, if the electrical rotating machines are adapted to their load. That way, it is possible, during the maintenance periods, to replace the older or faulty machines with machines offering the best efficiency taking into account the type of application.
- Electrical equipment noise and vibrations. The conception of silent electrical machines and transformers is synonymous of vibrations of low amplitudes. It means that stress and fatigue may be reduced. Then, designing machines with the lowest noise as possible is an actual challenge in terms of comfort, for transport application for example.
Two transversal key points intervene into these 3 research axes: the Life Cycle Analysis (LCA) and the experimental validations. The latter are performed with the platform S3E : Structures and Eco-Environmental Efficiency.
