Challenging PhD in Electromechanics and Power Electronics
The Eindhoven University of Technology has a vacancy for: PhD student for low frequency electrodynamic effects for accuracy in high-tech actuators in the Electromechanics and Power Electronics (EPE) group, Department of Electrical Engineering.
The Department of Electrical Engineering is one of the nine departments of the Eindhoven University of Technology (TU/e) and provides BSc and MSc programs in Electrical Engineering. The department has nine research groups and has research collaborations with other departments at the Eindhoven University of Technology as well as with a large number of other universities and companies, both within The Netherlands and internationally. The department has approximately 300 employees and 600 students.
The EPE group has a track record of developing dedicated design tools in close cooperation with industry. The PhD student will participate in an industrial research program and will collaborate intensely with the other members of the EPE group (around 40 researchers). The aim of his/her PhD research project is to research future proof electromagnetic dynamic models to improve the force prediction of electromagnetic actuators, where research within the EPE Group is characterized by personal supervision.
The accuracy of electro-mechanical actuation systems is highly important in many high-precision applications. For example in semiconductor lithography, the required position accuracy of non-linear actuators is in the nanometre range over a stroke of one millimetre. Further in low cost applications the minimization of energy is paramount. To obtain both position accuracy and low cost (optimal energy conversion), the error of the force/power prediction of high-precision actuators must be small. As such, flux density variations will be mapped on averaged equations for the flux density flow. However, saturation influences the Maxwell stress tensor which will need to be researched. This necessitates a further enhancement of the iterative approach including the summation of multiple charge surfaces or volumes. On lab-scale soft-magnetic geometries validations will be performed to match the flux tube behavior with in-house experiments.
“Low frequency electrodynamic effects for accuracy”
Dense flux density flows have been the subject of intense research over the past decades, owing to their wealth of scientifically interesting phenomena, as well as its direct relevance for innumerable industrial applications. Saturated flux density flows are always encountered in all industrially important electrical to mechanical energy conversion devices. At present, the validation of devices involving soft magnetic materials with non-linear characteristics is still a fully finite element based process. The research objective is to pioneer a multi-scale analytic methodology, based on charge modelling, for non-linear characteristics of soft magnetic structures. To date, analytic models mostly assume soft magnetic material infinitely permeable because this linearizes the treatment of flux density and boundary conditions. However, all soft magnetic materials in electrical machines are non-linear. This means that anisotropic saturation needs accounting for. Such electromagnetic structure variations are complex and many of the fundamental problems linked to flux tube orientation and boundary proximity appear and limit their application. This work will not only significantly advance our scientific understanding of saturation of soft magnetic materials, but also be extremely relevant to industrially important optimal energy conversion within high tech systems.
For this project, a candidate with MSc degree in Electrical Engineering, Physics or Mathematics will be selected and hired as doctoral student in the Electromechanics and Power Electronics Group (https://www.tue.nl/epe) for a 4-years period. The candidate should have an excellent knowledge and background in magnetic field modelling, affiliation with high-tech applications and a strong mathematical background. The candidate will closely cooperate with the other persons involved in the project. Previous experience with the design of non-linear electromagnetic modelling including the use of FE tools, is a must. Your CV must include a complete list of the marks obtained during your whole university career.
