摘要
An improved vector play model for magnetic hysteresis materials is proposed, and its required parameters are identified from the input major hysteresis loop. Validation results show that this new vector hysteresis model improves the accuracy of core loss computation not only for rotating fields but also for alternating fields compared with the ordinary vector play models. The presented model has been successfully implemented in 2-D and 3-D transient finite element analysis (FEA). Some application results from the 2-D and 3-D transient FEAs are presented.
