The existence of magnetic anisotropy in electrical steels has long been known to designers of electrical machines. However the effect of this anisotropy in real devices has not to date been studied in any great depth. Finite element modeling software is proving useful for designing such electrical machines, however, the material models which form the heart of the process are based on limited data and indeed often make incorrect assumptions regarding the anisotropic nature of the machine core. This article discusses shortcomings of present anisotropic material models, suggests what is needed to overcome these shortcomings and presents one such two-dimensional magnetic test system capable of generating the materials data required. The method by which the data is obtained is described and measured results are presented, indicating some of the features of the system. © 1996 American Institute of Physics.
