Abstract

La machine électrique tournante (1) comportant un carter comprenant des premier (14) et deuxième (15) paliers de serrage et une face interne, un stator comprenant un corps de stator (41) monté serré entre les premier et deuxième paliers de serrage et présentant une face externe s’étendant en regard de la face interne délimitant ensembles une chambre annulaire de refroidissement (21) entourant le corps de stator, le corps de stator comportant un empilement longitudinal de tôles de stator (410) dont chaque tôle de stator comporte un noyau annulaire présentant une circonférence externe et au moins deux excroissances radialement centrifuges s’étendant en saillie depuis la circonférence externe du noyau annulaire, dans la chambre annulaire de refroidissement, et diamétralement opposées l’une par rapport à l’autre, les tôles de stator de l’empilement longitudinal étant identiques et deux tôles de stator adjacentes de l’empilement longitudinal étant décalées angulairement l’une par rapport à l’autre de sorte que leurs excroissances respectives ne s’étendent pas l’une en regard de l’autre Figure pour l’abrégé : Fig. 2
