Modeling of Hysteresis Losses in Ferromagnetic Laminations under Mechanical Stress

摘要

A novel approach for predicting magnetic hysteresis loops and losses in ferromagnetic laminations under mechanical stress is presented. The model is based on combining an energy-based anhysteretic magnetoelastic constitutive law to a vector Jiles-Atherton hysteresis model. The hysteresis loops and losses are modeled accurately for stresses ranging from -50 to 80 MPa.
