An electric machine comprises an outer casing (2), a rotor and a stator (3) having at least one polar expansion (5) and at least one winding (8) having an annular shape and placed around the polar expansion (5). The casing (2) has a plurality of protrusions (13) each of which holds, by supporting, a corresponding portion (12) of a stator winding (8) to enable heat exchange between the winding (8) and the protrusion (13). Each portion (12) of the winding (8) is electrically insulated from the respective protrusion (13).
L'invention concerne une machine électrique comprenant un boîtier extérieur (2), un rotor et un stator (3) ayant au moins un épanouissement polaire (5) et au moins un enroulement (8) ayant une forme annulaire et placé autour de l'épanouissement polaire (5). Le boîtier (2) a une pluralité de saillies (13) dont chacune tient, par support, une partie correspondante (12) d'un enroulement de stator (8) pour permettre un échange de chaleur entre l'enroulement (8) et la saillie (13). Chaque partie (12) de l'enroulement (8) est électriquement isolée de la saillie respective (13).
