Electromagnetic Energy Conversion
The research field of electromagnetic energy conversion at the Institute for Power Electronic Systems (ELSYS) at Nuremberg Tech encompasses the design, analysis, and optimization of electric machines with the aim of improving the efficiency, power density, and thermal capacity of modern drive systems. In this context, various machine topologies and innovative machine concepts are investigated and evaluated in terms of their electromagnetic, thermal, and mechanical behavior.
Based on material properties identified through appropriate measurement setups, analytical and numerical methods for calculating and optimizing electric machines are employed to represent their behavior as accurately as possible. Using the developed models, predictions can be made regarding performance, loss distribution, and acoustic and thermal behavior.
The insights gained support the development of high-performance electric machines for applications, particularly in electromobility, industrial drive technology, aviation, energy, and automation technology.
