Charateristics Analysis on the Field System of Halbach Array by the Permanent Magnet

영구자석에 의한 Halbach 배열 자기시스템의 특성 해석

A new permanent magnet has been suggested the novel permanent magnet array using advanced analytical approaches in 1979 by Klaus Halbach. In this paper, the Halbach array is utilized to compose the field system. The ferro-magnetic materials of the electric machines cause the fatal energy loses in high frequency. But Halbach any enables to make the various field distribution without ferro-magnetic materials. This paper presents the magnetic characteristics are analyzed by the analytical method and FEM in case that the field system is composed of the Halbach array.
