Title (EN) ROTORS FOR ROTATING ELECTRICAL MACHINES
(FR) ROTORS DES MACHINES TOURNANTES ELECTRIQUES
Abstract:
(EN) The present invention relates to a rotor (1) for a rotating electrical machine, extending along a longitudinal axis (X), comprising: at least two poles defining an interpolated space (E) therebetween, and electrical conductor (4) windings (5) coiled about the poles, said windings (5) comprising a straight portion (6) extending along the longitudinal axis (X) of the rotor, at least one pole, particularly each pole, of the rotor comprising a crosspiece (10) placed along at least one part of the straight portion (6) between at least two groups of conductors of the windings (5) for providing at least one cooling channel between the two groups of conductors, thus enabling a longitudinal and/or transverse flow of cooling fluid into the windings (5), the crosspiece (10) comprising at least one crosspiece element (11, 111) having a hollow cross-section at least partially defining the cooling channel (12).
(FR) La présente invention concerne un rotor (1) pour machine électrique tournante, s'étendant selon un axe longitudinal (X), comportant : au moins deux pôles définissant entre eux un espace interpolaire (E) et, des enroulements (5) de conducteurs électriques (4) bobinés autour des pôles, ces enroulements (5) comportant une partie droite (6) s'étendant le long de l'axe longitudinal (X) du rotor, au moins un pôle du rotor, notamment chaque pôle du rotor, comportant une entretoise (10) disposée le long d'au moins une portion de la partie droite (6) entre au moins deux groupes de conducteurs des enroulements (5) pour ménager au moins un canal de refroidissement entre les deux groupes de conducteurs, permettant une circulation longitudinale et/ou transversale d'un fluide de refroidissement au sein des enroulements (5), P entretoise (10) comportant au moins un élément d' entretoise (11, 111) présentant une section transversale creuse, définissant au moins partiellement le canal de refroidissement (12).
