摘要：

A powder-aligning-fixture of anisotropic bonded Nd-Fe-B magnetic powder is designed to make a 4-pole polar anisotropic ring-type permanent magnet (PM). Magnetic performance of anisotropic bonded Nd-Fe-B PM under various aligning magnetic field intensities was investigated through analyses using equivalent magnetic circuit and 2-D finite element method (FEM). A cylinder-type bonded Nd-Fe-B PM having 4-pole polar anisotropy is realized by using the powder-aligning-fixture through an optimal design.
