Abstract

In rotating electric machines, magnetic material shows complex three-dimensional (3-D) properties due to rotational domains. In order to comprehensively analyze magnetic field distribution in the rotating flux machines, a 3-D magnetic properties testing system fit for cubic specimen has been constructed and modeled by means of finite element method (FEM). Taking the magnetic reluctivity tensor into account, this paper presents the modeling of 3-D tester core and analyzes the 3-D properties of a kind of SMC material. Experimental results are also presented to testify the rationality of design.
