Abstract
(DE) Die Erfindung betrifft einen Rotor einer elektrischen Rotationsmaschine, ein Verfahren zur Herstellung des Rotors sowie eine elektrische Rotationsmaschine mit dem Rotor. Der Rotor (1 ) umfasst eine Rotorwelle (10) und mit der Rotorwelle (10) verbunden wenigstens einen Rotorkörper (20), der wenigstens ein Blechpaket (21 ) aufweist, und einen an einer axialen Seite des Rotorkörpers (20) auf der Rotorwelle (10) mittels einer formschlüssig wirkenden Welle-Nabe-Verbindung (30) angeordneten Rotor einer Rotorlagesensor-Einrichtung (40) sowie eine Tellerfeder (50) aufweist, die zwecks Positionierung des Rotors der Rotorlagesensor-Einrichtung (40) dauerhaft eine axial wirkende Kraft (51 ) auf den Rotor der Rotorlagesensor-Einrichtung (40) ausübt, wobei sich der Rotor der Rotorlagesensor-Einrichtung (40) gegen die von der Tellerfeder (50) bewirkte axial wirkende Kraft (51 ) über ein der Tellerfeder (50) axial gegenüberliegendes Stützelement (60) an der Rotorwelle (10) abstützt. Der hier vorgeschlagene Rotor, das Verfahren zur Herstellung des Rotors sowie die den Rotor umfassende elektrische Rotationsmaschine erlauben eine einfache, flexible, kosteneffiziente und Bauraum-kompakte Montage und gewährleisten eine axiale Sicherung aller Rotorkomponenten.
(EN) The invention relates to a rotor for an electric rotation machine, to a method for producing the rotor, and to an electric rotation machine comprising the rotor. The rotor (1) comprises a rotor shaft (10), at least one rotor body (20) which is connected to the rotor shaft (10) and which has at least one laminated core (21), a rotor of a rotor position sensor device (40), said rotor being arranged on the rotor shaft (10) on the axial side of the rotor body (20) by means of a form-fitting shaft-hub connection (30), and a disc spring (50) which permanently exerts a force (51) acting in the axial direction on the rotor of the rotor position sensor device (40) for the purpose of positioning the rotor of the rotor position sensor device (40), wherein the rotor of the rotor position sensor device (40) is supported on the rotor shaft (10) against the force (51) acting in an axial direction produced by the disc spring (50) via a support element (60) lying axially opposite the disc spring (50). The aforementioned rotor, the method for producing the rotor, and the electric rotation machine comprising the rotor allow a simple, flexible, cost-efficient, and installation space-compact assembly and ensure an axial fixation of all of the rotor components.
(FR) L'invention concerne un rotor pour une machine électrique tournante, un procédé de fabrication du rotor, et une machine électrique tournante comprenant le rotor. Le rotor (1) comprend un arbre de rotor (10), au moins un corps de rotor (20) qui est relié à l'arbre de rotor (10) et qui présente au moins un noyau feuilleté (21), un rotor d'un dispositif de capteur de position de rotor (40), ledit rotor étant disposé sur l'arbre de rotor (10) sur le côté axial du corps de rotor (20) au moyen d'une liaison arbre-moyeu à complémentarité de forme (30), et un ressort à disque (50) qui exerce en permanence une force (51) agissant dans la direction axiale sur le rotor du dispositif de capteur de position de rotor (40) dans le but de positionner le rotor du dispositif de capteur de position de rotor (40), le rotor du dispositif de détection de position de rotor (40) étant supporté sur l'arbre de rotor (10) à l'encontre de la force (51) agissant dans une direction axiale produite par le ressort à disque (50) par l'intermédiaire d'un élément de support (60) situé axialement à l'opposé du ressort à disque (50). Le rotor mentionné ci-dessus, le procédé de fabrication du rotor, et la machine de rotation électrique comprenant le rotor permettent un assemblage simple, flexible, économique et d'installation peu encombrant et assure une fixation axiale de tous les composants de rotor.
