The improved process of the present invention seeks to best manage the compromise between optimization of noise reduction, power output, magnetic permeability, strength of materials and center of gravity in the manufacture of an alternator pole piece. The inventive steps include hot forging, shot blasting, Parkerization, cold coining, a two-step fully finishing step including a squeezing sub-step and a bending sub-step, and an annealing step. The inventive steps result in the manufacture of an alternator pole piece which facilitates quiet operation as well as high alternator output.
Le procédé perfectionné selon l'invention vise à trouver un bon compromis entre l'optimisation de la réduction de bruit, de la production de puissance, de la perméabilité magnétique, de la résistance des matériaux et du centre de gravité dans la fabrication d'un élément polaire pour alternateur. L'invention comprend les étapes suivantes; forgeage à chaud, grenaillage, parkérisation, matriçage à froid, double finition complète comprenant une opération de compression et une opération de pliage, et enfin traitement de recuit. Ces étapes inventives permettent de fabriquer un élément polaire pour alternateur favorisant un fonctionnement silencieux ainsi qu'une puissance de sortie élevée.
