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, de fournir de meilleures possibilités de réduire encore les pertes et de réaliser des résistances mécaniques plus élevées du rotor par rapport à l'état de la technique. Les pôles (5.1 à 5.7) de rotor sont ancrés à demeure sur le corps de base (3) de rotor par des embases polaires spécialement formées avec des réalisations structurales (4.3 et 4.4) constituées d'éléments de fixation (14.1 bis 14.4, 21.1, 21.2, 22) dans les pôles (5.1 à 5.7) de rotor et des vissages avec des vis amagnétiques à travers le corps de base (3) de rotor amagnétique en direction des pôles (5.1 à 5.7) de rotor et des auxiliaires d'orientation et de montage (18.1 à 18.15) pour orienter et ancrer les pôles (5.1 à 5.7) de rotor, des dents d'espacement interpolaire (8) séparées par des aimants permanents (1) étant situées en tant que corps d'aimant entre les pôles (5.1 à 5.7) de rotor, les embases (8.2) de dent d'espacement interpolaire étant ancrées à demeure par des réalisations également structurales (4.1 à 4.9) constituées d'éléments de fixation (14.1 à 14.4, 21.1, 21.2, 22) dans les dents d'espacement interpolaire (8) et des vissages avec des vis à travers le corps de base (3) de rotor en direction des dents d'espacement interpolaire (8) et des auxiliaires d'orientation et de montage (18.1 à 18.15) pour orienter et ancrer les dents d'espacement interpolaire (8) et les dents d'espacement interpolaire (8) étant conçues de manière à s'amenuiser en direction de la tête de dent d'espacement interpolaire (8.1) et les aimants permanents (1) formant ainsi avec leur axe de symétrie un angle par rapport au rayon du rotor. Selon le procédé, les pièces mécaniques individuelles sont tout d'abord montées, ensuite les aimants permanents (1) sont insérés et la fixation des aimants permanents (1) a lieu ensuite par collage et/ou imprégnation. Le domaine d'application de l'invention concerne la construction de machines électriques rotatives.
