CA 2278655

The present invention relates to a rotating electric machine incorporating a stator (1) with windings drawn through slots (5) in the stator. According to the invention the windings consist of high-voltage cable (6) wherein the slots (5) have alternate narrow parts (8) and wide parts (7) in radial direction, formed by the two walls of the slot. In a radial section the walls have a profile which, at the transition between the narrow and wide parts, lacks protruding corners where the walls abut the cable.

Cette invention a trait à une machine électrique tournante comportant un stator (1) pourvu de bobinages traversant les encoches (5) qu'il renferme. Les bobinages de l'invention sont constitués par un câble haute tension (6), les encoches (5) comportant une alternance de parties étroites (8) et de parties larges (7) dans le sens radial, formées par les deux parois de l'encoche. Dans une section radiale, les parois ont un profil qui, au point de transition entre les parties étroites et les parties larges, est dépourvu de coins en saillie là où les parois touchent le câble.
