La présente invention a pour objectif de résoudre le problème d'un stator d'une machine électrique rotative classique telle qu'un moteur électrique ou un générateur électrique, c'est-à-dire le problème de la diminution de manière annulaire de la largeur de dent d'une partie centrale dans laquelle est présente une section en creux, et en conséquence de l'augmentation de l'influence du couple de denture et de l'ondulation de couple, amenant de ce fait à une diminution de l'efficacité d'une machine électrique. Pour ce faire, au moins une section en creux (1a), ayant une ouverture de telle sorte que la largeur d'une dent (1) soit plus étroite, est formée au niveau d'une position spécifique dans la direction radiale d'un noyau de stator (2) dans chacune des deux surfaces latérales de la dent (1), l'ouverture s'étendant le long de la direction axiale du noyau de stator (2), et les sections en creux (1a) étant formées au niveau de positions différentes les unes par rapport aux autres dans les deux surfaces latérales de la dent (1).
