At present, questions regarding loss of performance of electromagnetic energy converters due to iron losses in rotating electrical machines cannot be answered at all or only with great simplifications in limited operating ranges on the basis of conventional material models. Within this project vector hysteresis models, each in primary B(H) and dual forms H(B), shall be integrated into finite element (FE) simulations to enable a FE-based spatially resolved magnetic field and iron loss calculation without restrictions of the investigated operating conditions.
