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 ...
