This paper describes an implementation of the rotational hysteresis analysis using the finite element method and a vector hysteresis model. The vector hysteresis model is extended from the magnetization-dependent Preisach model. The magnetization of each element is calculated for a given history of the rotating field. The lagging angle and the magnitude of the magnetization for an applied field are evaluated. The experimental results show that the magnetization characteristics of the magnetic materials under the rotating field can be analyzed accurately by the proposed method.
