Patent

CA 2255725

In a device for increasing the mechanical rigidity and natural frequency of the stator in a rotating electric machine, which stator is provided with teeth (10) between the slots (8) receiving the winding, the free ends of said teeth being located in the air gap (7) between stator and rotor, a spacer (11) increasing rigidity is arranged in each space between the free ends of adjacent stator teeth (10). These ends are thus fixed tangentially.

Dans un dispositif destiné à augmenter la rigidité mécanique et la fréquence naturelle du stator dans une machine électrique tournante, lequel stator est doté de dents (10) ménagées entre les fentes (8) recevant l'enroulement, les extrémités libres desdites dents étant situées dans l'entrefer (7) entre le stator et le rotor, un élément d'espacement (11) accroîssant la rigidité est agencé dans chaque espace situé entre les extrémités libres des dents adjacentes (10) du stator. Ces extrémités sont ainsi fixées de manière tangentielle.
