Abstract :
The paper describes the application of an advanced Finite Element Analysis (FEA) solver for the treatment of material magnetization: hysteretic behaviour prediction in soft ferromagnetic materials is outlined, demonstrating how remanent forces and hysteresis loss can now be accurately quantified. Results from analysis on a wound-field synchronous machine demonstrate the usefulness of the new algorithm in the design of such highly specialized devices.
