Abstract
In this study, a large-scale brushless doubly fed machine (BDFM) built in frame size D400 is tested at different operating conditions
in order to examine its noise and vibration levels. A series of measurements were conducted on the machine to establish the main modes of
excitation of vibration and noise developed by the machine. The harmonic spectrums of the vibration amplitudes are presented at two different
rotor speeds at which the vibration level is highest, in order to determine the vibration components frequencies existed in the vibration spectrum.
A harmonic analysis of the BDFM is then proposed in order to assess the sources of vibration in the machine.
