Improving Loss Properties of the Mayergoyz Vector Hysteresis Model

We present a new method for improving the magnetic loss properties of a certain class of isotropic vector hysteresis models based on the Mayergoyz model. We show that the Mayergoyz model possesses the necessary features for representing vector hysteresis but falls short of satisfying the loss property under rotating magnetic fields with magnitudes close to saturation. Therefore, we propose a new simple method to improve the loss property of the Mayergoyz model while keeping the essential features of the model. The method is based on removing the irreversible process persisting at saturation and hence correcting the magnetization behavior of the Mayergoyz model. We present thorough discussions about the properties of the new model as well as numerical results supported by experiments.
