A simplified anisotropic vector Preisach model(SAVPM)is proposed to describe the vector hysteresis characteristics of permanent magnet assemblies with high field strength in this paper. This vector Preisach model is consist of two basic orthogonal modified scalar Preisach models which are caculated through transforming functions independently, then state functions are introduced to avoid oversaturation. Combining this vector Preisach model and finite element analysis, the hysteresis characteristics of permanent magnet materials in the condition of high magnetic field are considered comprehensively. The method only requires the data of limiting magnetic hysteresis loops of the material along easy and hard axis, so the application of vector Preisach model become convernient and efficient. A sixteen elements enhanced magic ring is designed to verify the validity of the presented method furtherly.
