Description
Summary:Magnetic properties of electrical materials are of great significance to be accurately modeled and effectively incorporated in numerical analysis of electromagnetic fields. In this article, a hybrid technique (HYS) for solving nonlinear magnetic problems is proposed, combining the advantages of the traditional fixed-point (FP) technique and Newton-Raphson method (NRM). Besides, various material models of a nonoriented steel sheet considering nonlinearity, magnetic anisotropy, or vector hysteresis are constructed and combined with finite-element (FE) codes by means of different iteration algorithms. The adaptation relationship between material models and nonlinear solvers is investigated by simulating an eight-pole, 24-slot permanent magnetic synchronous motor (PMSM), and the efficiency of the presented method is validated.
