In this paper, a new vector hysteresis operator is proposed based on the microscopic magnetization mechanism of magnetic materials. Firstly, the magnetization mechanism of magnetic materials is analyzed, and an ideal self-consistent crystal model is proposed. Then the vector hysteresis operator is proposed based on the principle of energy minimum stability, considering the magnetocrystalline anisotropy energy and magnetostatic energy of cubic crystal materials. Finally, the validity of vector hysteresis operator is verified by the comparison of the experimental and simulation results of the silicon steel samples under the alternating current magnetic field. The proposed new vector hysteresis operator is helpful to improve the accurate simulation of magnetic properties of magnetic materials, which is of great significance in engineering applications.

摘要

In this paper, a new vector hysteresis operator is proposed based on the microscopic magnetization mechanism of magnetic materials. Firstly, the magnetization mechanism of magnetic materials is analyzed, and an ideal self-consistent crystal model is proposed. Then the vector hysteresis operator is proposed based on the principle of energy minimum stability, considering the magnetocrystalline anisotropy energy and magnetostatic energy of cubic crystal materials. Finally, the validity of vector hysteresis operator is verified by the comparison of the experimental and simulation results of the silicon steel samples under the alternating current magnetic field. The proposed new vector hysteresis operator is helpful to improve the accurate simulation of magnetic properties of magnetic materials, which is of great significance in engineering applications.
