Study of iron losses in machines operating at high speeds. Improvement of the dynamic contribution of the LS model and applications in Electric Vehicle applications
The work proposed concerns both the estimation and the determination of iron losses in an electrical machine operating at high speed for automotive application.
The estimation of the losses in the machine will be carried out using Flux2D ™ finite element simulations and the dynamic hysteresis model LS developed at G2Elab. The latter will be previously improved to better reflect the behaviour of the material at high frequency. The test machine will be supplied by Renault. The experimental measurements will be made at the G2Elab by adapting the Myghale test bench already available. The measured iron losses will be compared to the estimated iron losses by simulations. The observed deviations will be analysed quantitatively taking into account the approximations made during the simulations and the experimental measurement method used.
The candidate must have an Electrical Engineering background. He must be familiar with finite element simulations of electromagnetic devices and machine test benches. He must be methodical, rigorous and autonomous. Human qualities are also required for successful integration into the project team and interactions with laboratory members.
This work is part of the REGINOV project between G2Elab and Renault and aims to better estimate losses in machines operating at high speed.
The G2Elab (Grenoble Electrical Engineering Laboratory) covers a wide range of research: from materials for electrical engineering, to component design as well as the study and the control of complex systems such as electrical networks. With more than 100 permanent staff, 110 doctoral students and 50 masters, it is a major player in the field of Electrical Engineering Research, both in France and internationally.
The study will be carried out within the Madea team (Advanced Electromagnetic Materials and Devices) whose activities focus on the study of functional materials for Electrical Engineering, the design of innovative machines and devices that consume less energy and are more environmentally friendly. Complementary approaches are investigated by combining physical analysis, analytical and numerical modelling and experimentation. The team consists of about 45 people, including 15 permanent staff and 15 to 20 PhD. Within the laboratory, it has developed a platform for magnetic materials for characterization and a suitable electrical machine test bench that will be both used in this project. The candidate will also have at his disposal numerous calculation and numerical simulation tools including Matlab and Flux software to carry out his study.
