Abstract :
Presented in this paper is a vector hysteresis model for unoriented magnetic materials expanded from the magnetization-dependent Preisach model. Namely, the Preisach elements have rotational capabilities and they memorize their directions, and the Preisach plane is divided into reversible, irreversible regions and the regions maintaining their previous states. By integrating the Preisach plane vectorially for the magnitude-varying rotating field, the hysteresis phenomena such as the directions and magnitude of the magnetization and the hysteresis losses can be calculated
