Abstract

a. Dispositif de fermeture d'encoche dans des machines électriques. b. Dispositif caractérisé en ce qu'il est prévu comme fermeture d'encoche, des pièces en matériau ferro-magnétique en forme de bande ou bien cylindrique, dont le dimensionnement transversal est supérieur à la largeur d'ouverture de la fente d'encoche. c. L'invention s'applique notamment aux alternateurs de voitures automobiles.at. Notch closing device in electrical machines. b. Device characterized in that parts made of ferro-magnetic material in the form of a strip or else cylindrical, the transverse dimension of which is greater than the opening width of the notch slot, are provided as a notch closure. vs. The invention applies in particular to motor car alternators.
