“…N magnetic field analysis, the relationship between the magnetic field strength vector H and the magnetic flux density vector B can be expressed by the magnetic reluctivity or permeability [1]. For ferromagnetic materials, H and B are hardly parallel with each other under 2-D or 3-D excitation due to the magnetic domain wall motion and rotation of local magnetization vectors [2].…”

In this paper, a method of determining the three-dimensional (3-D) reluctivity tensor by measuring 3-D vector magnetic properties is presented. Taking the Soft magnetic composite (SMC) material which is applied to 3-D magnetic flux machines as an example, this paper describes the measurement of 3-D magnetic properties and the determination of 3-D magnetic reluctivity tensor which is a second-order three-dimensional full rank matrix. Taking the off-diagonal elements into account can help to accurate numerical analysis of magnetic field in 3-D flux electrical machines.

The flux density has a linear relationship with the magnetic field intensity when the flux density of a magnetic material is in the millitesla (mT) region. However in the high-frequency region, the magnetic flux is concentrated near the surface of the magnetic material owing to the skin effect. Therefore, it is necessary to consider the nonlinear magnetic properties of the material. In this paper, we propose a modified frequency response analysis method that takes into account the nonlinear distribution of the complex magnetic permeability with respect to the magnetic flux density, in order to accurately compute the magnetic flux distribution in the high-frequency range. The validity of the proposed analysis method is verified by comparing the computed data with measurements obtained by using a prototype (toroidal coil).
