In a device for increasing the mechanical rigidity and natural frequency of the stator in a rotating electric machine, which stator is provided with stator teeth between the slots (2) holding the winding (12), stator teeth (4, 6), the free ends of which are situated at the air gap between stator and rotor, have at least one yoke (14) formed in one piece with adjacent stator teeth, arranged across each stator slot in order to mechanically secure the stator teeth in tangential direction.
Cette invention a trait à un dispositif permettant de renforcer la rigidité mécanique et la fréquence propre du stator d'une machine électrique tournante, lequel stator comporte des dents situées entre les encoches (2) maintenant le bobinage (12). Ces dents (4, 6), dont les extrémités libres se trouvent au niveau de l'entrefer entre le stator et le rotor, possèdent au moins un étrier (14). Celui-ci, qui est formé d'une seule pièce avec la dent adjacente, est placé entre les encoches de manière à assujettir mécaniquement les dents du stator dans le sens tangentiel.
