Abstract

L'invention concerne une pièce de machine (10), en particulier un rotor ou un stator d'une machine électrique. La pièce de machine (10) comprend un paquet (12) constitué d'une pluralité de tôles empilées, au moins un aimant (16) installé dans un logement (14) formé dans le paquet (12). Une des tôles est formée de manière à comporter au moins une languette de fixation (18) qui s'avance dans le logement (14) et fixe l'aimant (16) dans le logement (14), et la languette de fixation (18) est conçue pour être au moins en partie déformée plastiquement par l'aimant (16) lorsqu'elle est insérée.
