Abstract

In order to comprehensively understand magnetic field distribution in soft magnetic composite (SMC) materials which apply to three-dimensional (3-D) flux electrical machine design, 3-D reluctivity tensor should be taken into account. A 3-D magnetic properties testing system fitting for cubic SMC sample has been constructed and calibrated by means of finite element method (FEM). According to the experimental data from 3-D magnetic property tester, this paper presents the modeling of 3-D magnetic reluctivity tensor, which can be written to a 3×3 full rank matrix. Laboratory results and FEM analysis are presented to testify the rationality of design and optimize the performance of electromagnetic devices.
