Abstract
This article presents a hysteresis model that incorporates the microstructural features of soft magnetic composites (SMCs). The anhysteresis curve is derived based on Globus’s model, which characterizes the continuous displacement of the domain wall within the particles. A static hysteresis model is then formulated by incorporating the particle size-related pinning field in the energy-based (EB) model to describe irreversible displacement. An inverse dynamic model is further developed considering the relation between the eddy current effect and particle size. The model accuracy is validated by comparing the calculated hysteresis loops and iron loss of two types of SMCs samples with experimental results under both quasi-static and dynamic conditions.
