Vibration Analysis for Alternator Stator of Automobile by Finite Elmental Method

Abstract

Reductione of the noise emitted from the automobile alternator has recently become a serious issue, especially in relationship to the improvement of the amenity of driving. In order to design a quiet automobile alternator, a designer needs to anticipate all important resonant frequencies of the alternator stator. We intend to simulate the electromagnetic vibration behavior of the stator using finite element method. The results obtained are applicable to alternator design for the reduction of noise.
