Study on vector magnetic properties of magnetic materials using hybrid hysteresis model

This paper presents a method to study the vector magnetic properties of magnetic materials under alternating and rotational magnetic field using 2-D vector hybrid hysteresis model. Combining Preisach model and Stoner-Wohlfarth (S-W) model, the vector hybrid hysteresis model is established for magnetic materials. The alternating and rotational hysteresis properties are calculated under different excitation frequency, respectively. And the computed results are compared with the experimental measurement ones. It is shown that the vector model can simulate the alternating and rotational magnetic properties effectively under low magnetization fields and low excitation frequency.
