Abstract

Procédé de fabrication et stator de machine électrique tournante avec bobinage asymétrique Procédé de fabrication d’un stator (2) de machine électrique tournante (1), comportant les étapes suivantes : (a) fournir une masse statorique (25), la masse statorique (25) comportant des encoches (21) ménagées entre des dents (23), des conducteurs électriques (22) étant logés dans les encoches (21), au moins une partie des conducteurs électriques étant en forme d'épingle en U ou en I, comportant chacun des jambes intérieure (22e) et extérieure (22f), au moins une des jambes intérieure (22e) et extérieure (22f) des conducteurs électriques (22) se prolongeant hors des encoches par une portion de soudage, (b) décaler circonférentiellement les jambes extérieures (22f) des conducteurs électriques d’un demi pas dentaire par rapport aux jambes intérieures (22e), et (c) décaler radialement vers l’extérieur les jambes extérieures (22f) de certains conducteurs électriques, notamment les jambes extérieures des conducteurs électriques d’entrée et/ou de sortie de phase. Figure pour l’abrégé : Fig. 1Method of manufacturing and stator of a rotating electrical machine with asymmetric winding Method of manufacturing a stator (2) of a rotating electrical machine (1), comprising the following steps: (a) providing a stator mass (25), the stator mass (25) comprising notches (21) formed between teeth (23), electrical conductors (22) being housed in the notches (21), at least a portion of the electrical conductors being in the shape of a U-shaped or I-shaped pin, each comprising inner (22e) and outer (22f) legs, at least one of the inner (22e) and outer (22f) legs of the electrical conductors (22) extending out of the notches by a welding portion, (b) circumferentially offsetting the outer legs (22f) of the electrical conductors by half a tooth pitch relative to the inner legs (22e), and (c) radially offsetting outwardly the outer legs (22f) of some electrical conductors, in particular the outer legs of the phase input and/or output electrical conductors.
