The present invention relates to a stator (1) for a rotating electric machine, comprising a stator frame (6), a stator core (2) and a winding (4) arranged in slots in said stator core, characterized in that said stator is built of at least two self-supporting stator elements (12, 13, 14; 18, 19; 27, 28, 29, 35, 36, 37) of a substantially annular disc shape, and that the axial length l of said stator elements is defined by one or more dividing planes (8, 9, 10; 20; 30, 31) perpendicular to the longitudinal axis (11; 21) of the stator. The invention also includes a method of manufacturing a stator and a rotating electric machine including such a stator.
L'invention concerne un stator (1) destiné à une machine électrique rotative. Ce stator comprend une carcasse (6), un noyau (2) et un enroulement (4) placé dans des fentes du noyau de stator. L'invention est caractérisée en ce que le stator est constitué d'au moins deux éléments stator autoporteurs (12, 13, 14; 18, 19; 27, 28, 29, 35, 36, 37) ayant la forme d'un disque sensiblement annulaire et en ce que la longueur axiale l de ces éléments stator est définie par au moins un plan de séparation (8, 9, 10; 20; 30; 31) perpendiculaire à l'axe longitudinal (11; 21) du stator. L'invention concerne également un procédé de production d'un stator et une machine électrique rotative comprenant un tel stator.
