摘要

在旋转电机中，由于旋转域的存在，磁性材料表现出复杂的三维(3-D)性质。为了全面分析旋转磁通机的磁场分布，构建了一个适合立方体试样的三维磁特性测试系统，并采用有限元方法对其进行了建模。在考虑磁阻张量的情况下，建立了三维测试磁芯模型，并对某SMC材料的三维性能进行了分析。实验结果验证了设计的合理性。

Modeling and analysis of 3-D tensor magnetic reluctivity properties of soft magnetic composite material

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.
