Abstract The rotational flux in the core of power transformer and motor causes the inaccuracy efficiency computation of magnetic apparatus. In order to address the problem, this work focuses on magnetic measurement of rotational magnetization and its hysteresis loss modeling. Firstly, the vector hysteresis loss is decomposed into the transverse and radial components which are defined based on rotational loss and alternating loss, respectively. Secondly, the model parameters of soft magnetic composites and non-oriented silicon steel are identified. Their magnetic properties and model parameters are compared and analyzed. Finally, a series of complex excitation magnetization experiments on non-oriented silicon steel are carried out. The measurement results are compared with the predicted values by the model. It shows that the proposed model gives more exact predicted results than the traditional Steinmetz method.
