Abstract
In order to clarify the iron loss distribution in iron core of electric machines, the magnetic field analysis considering 2-D vector magnetic properties is effective. Several kinds of modeling of 2-D vector magnetic properties are proposed, the complex E&S modeling is most simplified and is useful to optimal design of electric machines. 2-D vector magnetic properties used in analysis are defined by three parameters, the maximum magnetic flux Bmax, the inclination angle θB, and the axis ratio α. However we obtain the amplitude and the phase shift of magnetic flux densities when we calculate the finite element analysis which introduced the complex E&S modeling. Therefore we have to recalculate the three parameters from the amplitude and the phase difference of magnetic flux densities. In this paper, we define the amplitude and the phase difference of magnetic flux densities as parameters of the 2-D vector magnetic properties, carry out the finite element analysis which introduced the complex E&S modeling.
