초록
Klaus Halbach has suggested the novel permanent magnet array using advanced analytical approaches in 1979. We utilize this Halbach array to compose the field system of high speed motor-generator. The ferro-magnetic materials of the electric machines cause the fatal energy loses in high frequency. But Halbach array enables to make the various field distribution without ferro-magnetic materials. Therefore, the energy loses can be reduced. This paper presents the magnetic characterics of Halbach array and the application to the motor-generator.
