Abstract

La présente invention propose un rotor pour machine électrique tournante de véhicule automobile. Le rotor (4), monté rotatif autour d'un axe (X), comporte au moins un élément magnétique (29) et une paire de roues polaires (17) comportant chacune : - un flasque (18), - une pluralité de griffes (19) s'étendant axialement à partir dudit flasque (18), comportant un corps de griffe (22) présentant une longueur de griffe (A) définie entre le flasque (18) et une extrémité libre (23) dudit corps de griffe et comportant au moins une lèvre de maintien (30) d'un élément magnétique (29) agencée de manière contigüe audit corps de griffe et en regard d'une griffe adjacente de l'autre roue polaire, la lèvre de maintien (30) s'étendant axialement sur une longueur dite longueur de lèvre (B), ladite longueur de lèvre (B) étant inférieure à ladite longueur de griffe (A).The present invention provides a rotor for a rotating electric machine of a motor vehicle. The rotor (4), rotatably mounted about an axis (X), comprises at least one magnetic element (29) and a pair of pole wheels (17) each comprising: - a flange (18), - a plurality of claws (19) extending axially from said flange (18), having a claw body (22) having a claw length (A) defined between the flange (18) and a free end (23) of said claw body and having at least one retaining lip (30) of a magnetic element (29) arranged contiguously with said claw body and facing an adjacent claw of the other pole wheel, the retaining lip (30) is extending axially over a length called lip length (B), said lip length (B) being less than said claw length (A).
