Taking modeling accuracy versus modeling complexity into account, this paper proposes a general and accurate iron loss calculation method considering harmonics based on the Loss Surface(LS) hysteresis model and Finite Element Method(FEM). Compared with the previous triangular wave excitation, this paper uses the data under sinusoidal wave excitation to establish the LS model, which is more convenient for engineering application. A specimen is tested for different flux density with harmonics, the extensive results verify the modeling method. Due to a powerful hysteresis model, iron loss calculation can be realized by directly integration of hysteresis loops. A separated iron loss calculation package is developed, and it is combined with the commercial finite element software to compute the iron loss distribution. The method that combines the LS model and FEM is proved feasible by comparing the calculated iron loss with the measured one for the Epstein frame. date: 2020 type: Article type: PeerReviewed identifier: Zhu, Qinyue and Wu, Quanpeng and Li, Wei and Pham, Minh Trien and Zhu, Lixun (2020) A General and Accurate Iron Loss Calculation Method considering Harmonics based on Loss Surface Hysteresis Model and Finite Element Method.
