The objective of this research is to realize a small and ultra-high speed motor by employing a homo-polar type bearingless motor (HBM). A bearingless motor combines functions of both non-contact magnetic suspension and rotation. A rotor of the HBM consists of only iron cores, and thus resistance to centrifugal force and heat while ultra-high speed operation is improved in comparison to a conventional surface-mounted permanent magnet rotor. An already reported HBM has an eight-pole rotor and distributed windings in the stator. To reduce the size and iron losses in ultra-high speed region, a simple HBM with concentrated windings and a six-pole rotor has been proposed. In this paper, an optimal winding configuration to reduce the variation and direction error of the suspension force against rotating angles has been investigated.
