CD Laboratory for Multiphysical Simulation, Analysis and Design of Electrical Machines

The foundations for a comprehensive simulation of the position of electrical machines are developed. The electromagnetic, thermal, mechanical and acoustic aspects of such machines are given special consideration.

An efficient electrical machine requires the consideration of various physical phenomena and their interactions as early as the planning phase. Tolerance values for materials and components must also be taken into account. This makes their development a major challenge for engineering science, which will be easier to overcome in the future thanks to research.

Existing and new findings on the individual physical phenomena are combined with the relevant tolerance values for mechanical engineering by means of calculation. In some cases, new mathematical formulations and suitable algorithms are being developed to enable comprehensive simulation. Laboratory tests will subsequently verify the suitability of the simulation models. At the same time, these tests allow the derivation of new description methods for the phenomena occurring in machines.

These phenomena, which must be taken into account in research activities, include electric and magnetic fields and forces. Furthermore, these forces and the movement of machine parts generate heat, which can lead to thermal problems. However, vibrations also occur, which in turn interact with other physical phenomena and are also responsible for noise generation. The development of design and simulation tools is therefore a multi-physical process that must combine the fields of electromagnetism, thermodynamics and hydromechanics with structural mechanics and acoustics.

Overall, the research will create the basis for robust design and simulation tools for electrical engineering. This will make it possible to develop machines that function almost perfectly at their technical limits.
