Abstract

L'invention entre dans le domaine des machines électriques tournantes. Procédé de fabrication d'un rotor de moteur asynchrone à cage d'écureuil en aluminium coulé comportant des canaux radiaux de ventilation dans lequel afin d'assurer la continuité du moule constitué par les encoches du circuit magnétique, dans les sections de ce circuit interrompu pour la réalisation des canaux radiaux, on place des tôle particulières encochées de la même manière que les tôles du circuit magnétique et comportant en outre des évidements supplémentaires ouverts vers l'extérieur après la coulée de la cage par tournage Application : machine asynchrone de grosse puissance.The invention enters into the field of rotating electrical machines. A method of manufacturing an asynchronous motor rotor with squirrel cage in cast aluminum comprising radial ventilation channels in which, in order to ensure the continuity of the mold formed by the notches of the magnetic circuit, in the sections of this circuit interrupted for the production of the radial channels, special notched sheets are placed in the same way as the sheets of the magnetic circuit and further comprising additional recesses open to the outside after the casting of the cage by turning Application: high power asynchronous machine.
