Abstract[German]
Die Erfindung betrifft einen Rotor (1) für eine elektrische Maschine (2), insbesondere für eine permanent erregte Synchronmaschine, - mit einer um eine Rotationsachse (3) rotierbaren Welle (4) und einem mit der Welle (4) drehfest verbundenen Träger (5) mit in Axialrichtung (24) ausgerichteten Aufnahmen (6), - wobei in den Aufnahmen (6) Permanentmagnete (7) angeordnet sind. Erfindungswesentlich ist dabei, dass eine nicht-magnetische, austenitische Metallhülse (8) vorgesehen ist, die den Träger (5) und die Permanentmagnete (7) umgibt.[English]
The invention relates to a rotor (1) for an electric machine (2), in particular for a permanently excited synchronous machine, - comprising a shaft (4) able to rotate about an axis of rotation (3), and a carrier (5) that is connected to the shaft (4) for conjoint rotation and has receptacles (6) oriented in the axial direction (24), - permanent magnets (7) being arranged in the receptacles (6). It is essential to the invention that provision is made for a non-magnetic, austenitic metal sleeve (8) that surrounds the carrier (5) and the permanent magnets (7).[French]
L'invention concerne un rotor (1) pour une machine électrique (2), en particulier pour une machine synchrone à excitation permanente, - comprenant un arbre (4) pouvant tourner autour d'un axe de rotation (3), et un support (5) qui est relié à l'arbre (4) pour une rotation conjointe et comporte des réceptacles (6) orientés dans la direction axiale (24), - des aimants permanents (7) étant disposés dans les réceptacles (6). Il est essentiel pour l'invention qu'un manchon métallique austénitique non magnétique (8) qui entoure le support (5) et les aimants permanents (7) soit prévu.
