© 2018 KIEE EMECS (KIEE Electrical Machinery and Energy Conversion Systems). This paper introduces a vector hysteresis operator based on the physical mechanisms of the magnetic material. With the help of the schematic diagrams of energy barrier and the traditional wind-rose method, the magnetization orientation of each operator under different rotational magnetic field can be determined, as well as the rotation process of the corresponding magnetization. Meanwhile, a two-dimensional distribution function is utilized to describe the density of the interacting operators in the given specimen. To verify this rotational hysteresis model, the magnetic properties of soft magnetic composite SOMALOY™ 500 under different rotational excitations have been simulated and compared with the experimental results. Besides, the error analysis has been given to demonstrate the significance of parameters in the distribution function. The comparison shows the practicability of this vector operator and the wind-rose method.
