Title (EN) INJECTED-CAGE ROTOR
(FR) ROTOR A CAGE INJECTEE
Abstract:
(EN) Rotor of a rotary electric machine, comprising a bundle (2) of magnetic laminations (113), the magnetic laminations (113) comprising openings (3) forming slots (4) within the bundle (2), the bundle (2) comprising at least one keeper lamination (110) at one of its axial ends, bars (10) of a first electrically conducting material housed in at least part of the slots (4), these bars (10) coming to bear at one axial end against the said keeper lamination (110), with a second electrically conducting material (20) being injected into the slots (4).
(FR) Rotor de machine électrique tournante, comportant un paquet (2) de tôles magnétiques (113), les tôles magnétiques (113) comportant des ajours (3) formant des encoches (4) au sein du paquet (2), le paquet (2) comportant au moins une tôle de garde (110) à l'une de ses extrémités axiales, des barres (10) d'un premier matériau électriquement conducteur reçues dans une partie au moins des encoches (4), ces barres (10) venant en appui à une extrémité axiale contre ladite tôle de garde (110), un deuxième matériau (20) électriquement conducteur injecté dans les encoches (4).
