Abstract

In this paper, the magnetization directions of a polar anisotropic ferrite-bonded magnet are analyzed by finite element method (FEM). The influence of the width of SmCo magnets for magnetic field generation is invested. And, the surface flux densities of the polar anisotropic magnets are analyzed and compared according to the magnet pole number and thickness. The validity of the analysis method is verified by comparing the analyzed results with measured ones.
