Efficiency and power density of electrical drives are a direct result of the materials used, predominantly the magnetic properties of the non-grain oriented electrical steel. In order to minimize losses it is necessary to correlate the causes within the material with the resulting electromagnetic properties. Complex interdependencies over the entire process chain affect the material and thus, its properties. Therefore, the evolution of texture, microstructure and residual stresses of the material during the processing needs to be investigated. This enables the improvement of simulation models and thereby, aides the machine design process and process optimization. This interdisciplinary DFG research group works on this challenging task
