초록
The magnetic bearing is an important element for high-speed system, such as semiconductor equipment and machine tools. Particularly, The homopolar magnetic bearing has the advantages of lower power losses, more space for heat dissipation and coil winding. This paper deals with analysis and comparison of the homopolar magnetic bearing according to four different PM structures. On the basis of these results, we find one homopolar magnetic bearing superior to the others. finally, this paper derive force characteristic equation for this model and deals with comparison of between analytical and FE results.
