Abstract

L'invention concerne une machine à réluctance synchrone (20), en particulier un moteur ou générateur d'une puissance supérieure à 300 kW, comprenant un stator (1) et un rotor (3) qui est espacé par un entrefer (19), qui est logé de manière à pouvoir tourner sur un axe (18) dont les feuillets disposés axialement les uns derrière les autres ont chacun une structure magnétique anisotrope qui est formée par des parties de blocage de flux (14, 15, 16) et des parties de conduction de flux (8) et les parties de blocage de flux (14, 15, 16) et les parties de conduction de flux (8) forment des pôles du rotor (3). Ces parties de blocage de flux (14, 15, 16) forment des conduits s'étendant axialement. Des aimants permanents sont prévus dans au moins certaines des partie de blocage de flux (14, 15, 16), lesquels aimants n'occupent pas complètement la partie de blocage de flux respective (14, 15, 16) et permettent ainsi un écoulement d'air axial dans toutes les parties de blocage de flux (14, 15, 16). Le noyau feuilleté du rotor (3) est divisé axialement en au moins deux parties de noyau feuilleté (30, 31, 32, 33). Des fentes de refroidissement radiaux (6) sont ménagées respectivement entre les pôles dans la région de l'axe q, lorsque l'on regarde dans la direction circonférentielle, et entre les parties de noyau feuilleté (30, 31, 32, 33), lorsque l'on regarde axialement.
