Title (EN) ROTOR HAVING AN INJECTED CAGE
(FR) ROTOR A CAGE INJECTEE
Abstract:
(EN) The invention relates to a rotor (1) for a rotary electric machine, having a stack of magnetic laminations (2) that each have perforations (3), the superposition of these perforations (3) within the stack (2) forming notches (4), at least some of the perforations (3) having, on at least part of their periphery, friction reliefs, electrically conductive bars (10) of a first material, which are received in at least some of the notches (4) and bear against said reliefs by at least one main face (11).
(FR) Rotor (1) pour machine électrique tournante, comportant un paquet de tôles magnétiques (2) présentant chacune des ajours (3), la superposition de ces ajours (3) au sein du paquet (2) formant des encoches (4), au moins une partie des ajours (3) présentant sur au moins une partie de leur pourtour des reliefs de friction, des barres (10) électriquement conductrices d'un premier matériau, reçues dans au moins une partie des encoches (4) et venant en appui par au moins une face principale (11) contre lesdits reliefs.
