Abstract

L'invention concerne un rotor pour un arbre d'une machine électrique à flux axial. Le rotor présente un alésage de palier central pour l'arbre de machine et plusieurs aimants permanents sont disposés en cercle autour de l'alésage de palier ou de l'arbre de machine et s'étendent à travers une ouverture respective dans le rotor et sont retenus respectivement dans le rotor contre un déplacement axial ou radial. Le rotor selon l'invention est constitué, dans un mode de réalisation, de deux disques identiques, disposés en vis-à-vis l'un par rapport à l'autre et reliés ensemble, chaque disque présentant d'une part un côté plan et d'autre part une structure sur le côté opposé, laquelle est constituée d'une pluralité de dépressions réparties uniformément et d'une pluralité d'élévations réparties uniformément. Les élévations de chaque disque s'engagent par complémentarité de forme, après l'assemblage des disques, dans les dépressions de l'autre disque et les côtés plans des disques forment les côtés extérieurs du rotor. Les ouvertures pour les aimants permanents présentent respectivement sur leur côté orienté vers les côtés plans des disques ou côtés extérieurs du rotor un bord périphérique en retrait sur lequel l'aimant permanent s'appuie dans la direction axiale. Le bord périphérique des ouvertures permet, lors du montage du rotor, que les aimants permanents puissent être insérés par complémentarité de forme dans les ouvertures du premier disque et y soient maintenus de manière à ne pas pouvoir en tomber ou se déplacer. Lorsque le premier disque a été équipé de tous les aimants permanents, le deuxième disque est placé sur le premier disque et centré dans celui-ci par les dépressions et les élévations.
