Noise and vibration in brushless doubly fed machine and brushless doubly fed reluctance machine
IET Electric Power Applications, 2014 This study investigates modes of vibration in brushless doubly fed machine and brushless doubly fed reluctance machine due to the interaction of its fundamental magnetic fields, via the bending forces they set up in the back iron. It is shown that the presence of two field components of different pole numbers leads to vibration components in addition ...

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.
