Modelling and Experimental Verification on Magnetic Hysteresis Properties of Soft Magnetic Composite Material

摘要

This paper in magnetic troduces some research results about the magnetic characteristics on soft composite (SMC) material. Based on the mechanisms of magnetic material magnetization, a vectorial hysteresis model is proposed to simulate the hysteresis characteristics of SMC material. Meanwhile, by using the three dimensions magnetic properties test platform, the magnetic features of SMC material under different applied magnetic fields, such as alternating field and rotational field, have been measured. To verify this presented vectorial hysteresis model, a given SMC material is employed to be simulated and measured under rotating and alternating excitations, respectively. Compared with the two results, a good agreement can be obtained, which shows the validity and practicability of the proposed hysteresis model.
