Abstract
By using statistical approaches, a calculation model of anomalous loss in magnetic materials is built on the basis of the production of anomalous loss and domain wall motion. Based on that, a macrophysical interpretation of this model is described in detail, and a testing method to determine the microstatistical characteristic parameters is proposed due to the pure anomalous loss obtained by the separation of total experimental core losses in electrical steel sheets. Meanwhile, the characteristics of the coefficient of anomalous loss are analyzed. In addition, rotating anomalous loss can be extended in this model. Therefore, under trusted error range, the separated and predicted values of alternating and three-dimensional rotating anomalous losses are compared and analyzed, respectively. The results clearly underline the necessity of achieving more accurate loss coefficients.
