Abstract

L'invention a pour but de réaliser des modules de rotor excités en permanence et modifiables pour des hauteurs d'axe, des vitesses de rotation et des sollicitations mécaniques et électromagnétiques très différentes, une réduction de la masse des aimants permanents ainsi qu'une assurance d'une épaisseur d'entrefer optimale en présence d'un flux de dispersion minime et une résistance mécanique élevée du rotor pour atteindre une vitesse de rotation très élevée devant être obtenues. Le rotor multipolaire à aimants permanents comprenant des aimants permanents (1) orientés tangentiellement, disposés de manière protégée et affleurante entre les pôles (2) de rotor qui sont fixés sur un corps de base (3) de rotor a des pôles (2) de rotor avec des embases (2.2) spécialement formées et des réalisations structurales (4.1 à 4.12 et 4.16 à 4.19) constituées d'éléments de fixation (10.1 à 10.4) et d'auxiliaires d'orientation et de montage (11.1 bis 11.3, 11.7, 11.11 bis 11.13) pour orienter et ancrer les pôles (2) de rotor dans des rainures de fixation (8) complémentaires qui sont ancrées à demeure dans le corps de base (3) de rotor amagnétique. Les aimants permanents (1) ont par des coins d'espacement interpolaire amagnétiques (5.1 à 5.4) des possibilités de fixation supplémentaires. Une fixation analogue au moyen de dents de fixation (7) du corps de base (3) de rotor dans les pôles (2) de rotor est possible. Selon le procédé, des éléments de fixation qui sont en partie préalablement refroidis sont enfoncés ou vissés. Le domaine d'application de l'invention relève de la construction de machines électriques rotatives.
