Abstract

The magnetization directions of a polar anisotropic ferrite-bonded magnet are analyzed by finite element method (FEM). The influence of the width of Sm-Co magnets for magnetic field generation is investigated. The surface flux densities of the polar anisotropic magnets are analyzed and compared according to the pole number and thickness of the magnets. And the electromotive force (EMF) values of brushless DC motors with the magnets are investigated.
