Accuracy Improvement of Magnetic Hysteresis Calculated by LLG Equation

Quantitative estimation of iron loss including magnetic hysteresis behavior is essential to the development of high-efficient electrical machines. A simplified micromagnetic model using Landau-Lifshitz-Gilbert (LLG) equation is one of the useful models for calculating the hysteresis behavior. However, further improvement of the calculation accuracy under magnetic saturation is required. This paper presents the accuracy improvement of the magnetic hysteresis calculated by the LLG equation.
