A Novel Computational Method to Identify/Analyze Hysteresis Loops of Hard Magnetic Materials

In this study, a novel computational method capable of reproducing hysteresis loops hard magnetic materials is proposed. It conceptually based on the classical Preisach model but has completely different approach in modeling hysteron effect. Indeed, change magnetization caused by single compared here to velocity two disk-shaped solids elastically colliding with each other rather than effect ideal geometrical entities giving rise so-called Barkhausen jumps. This allowed us obtain simple differential formulation for global equation significant improvement terms performance. A sensitivity analysis parameters proposed indeed shown capability large class loops. Moreover, permits temperature neodymium magnets, which key point design electrical machines. Therefore, application loop real NdFeB magnet been proven be very accurate and efficient range.
