High-Strength Undiffused Brushless (HSUB) Machine [PDF]
2008 IEEE Industry Applications Society Annual Meeting, 2008 This paper introduces a new high-strength undiffused brushless machine that transfers the stationary excitation magnetomotive force to the rotor without any brushes. For a conventional permanent magnet (PM) machine, the air gap flux density cannot be enhanced effectively but can be weakened.
