2-D vector magnetic properties accurately represent the magnetic properties of various kinds of electrical steel sheets, because they can represent an alternating magnetic field in any direction and a rotating magnetic field by using the relationship between the flux density vector B and the field strength vector H. E&S modeling is proposed as a method for representing 2-D vector magnetic properties in magnetic field analyses. However, the E&S modeling used in magnetic field analyses is very time-consuming. To solve this problem, we propose complex E&S modeling on the assumption that both the flux density and field strength waveforms are sinusoidal. We carried out FEM analyses taking account of complex E&S modeling. Finally, we compared the analyses results considering complex E&S modeling with those of conventional E&S modeling, and made clear the efficiency of complex E&S modeling.
