Magnetic properties of electrical materials are of great significance to be accurately modeled and effectively incorporated in numerical analysis of electromagnetic fields. In this paper, a hybrid technique for solving nonlinear magnetic problems is proposed, combining the advantages of traditional fixed-point technique and Newton-Raphson method. Besides, various material models of a non-oriented 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 are investigated by simulating an 8-pole, 24-slot permanent magnetic synchronous motor (PMSM) and the efficiency of the presented method is validated.
