Abstract :
This paper aims to describe a numerical modeling process for estimating the electromagnetic noise radiated from a permanent magnet synchronous machines. The original contributions concern the inclusion of a complete evaluation of the electromagnetic forces acting on the stator teeth, a complete 3-D structural finite-element model and a point wise approximation for acoustic calculation. Structural and acoustic responses of the targeted machine have been derived and validated using experiments. Superior precision of the proposed method has been substantiated through experiments.
