Abstract :
Eccentricity is considered as a major problem for every people dealing with the realization of an electrical machine. Generally linked to manufacturing tolerances and rotor balance quality, rotor dynamic eccentricities contribution to vibro acoustic behaviour of the machine is here investigated for a synchronous machine during a full run up. We will establish, thanks to finite element models coupling, that additional harmonics linked to eccentricities lead to new acoustic noise components. Finally a direct link between eccentricity and vibratory level will be achieved.
