Abstract[German]
Die Erfindung betrifft einen Rotor (1) für eine elektrische Maschine, insbesondere für eine fremderregte Synchronmaschine. Der Rotor (1) umfasst eine Welle (2), einen Wicklungsträger (3) mit mehreren Wicklungen (4) und mehrere zwischen den Wicklungen (4) angeordnete Verschlusskeile (6). Wenigstens einer der Verschlusskeile (6) umfasst wenigstens zwei Keilstücke (19a, 19b), die zu dem Verschlusskeil (6) stoffschlüssig und/oder formschlüssig miteinander verbunden sind. In dem Verschlusskeil (6) ist dabei ein Strömungspfad (16) ausgebildet, der zu den zu dem Verschlusskeil (6) benachbarten Wicklungen (4) zumindest teilweise offen ist.[English]
The invention relates to a rotor (1) for an electric machine, in particular for a separately excited synchronous machine. The rotor (1) comprises a shaft (2), a winding carrier (3) having a plurality of windings (4), and a plurality of closure wedges (6) arranged between the windings (4). At least one of the closure wedges (6) comprises at least two wedge pieces (19a, 19b) which are integrally and/or interlockingly connected to one another to form the closure wedge (6). A flow path (16) is formed in the closure wedge (6), said flow path being at least partially open to the windings (4) adjacent to the closure wedge (6).[French]
L'invention concerne un rotor (1) pour une machine électrique (2), en particulier pour une machine synchrone à excitation séparée. Le rotor (1) comprend un arbre (2), un support d'enroulement (3) ayant une pluralité d'enroulements (4) et une pluralité de cales de fermeture (6) disposées entre les enroulements (4). Au moins l'une des cales de fermeture (6) comprend au moins deux parties cale (19a, 19b) qui sont reliées d'un seul tenant et/ou par complémentarité de forme l'une à l'autre pour former la cale de fermeture (6). Un trajet d'écoulement (16) est formé dans la cale de fermeture (6), ledit trajet d'écoulement étant au moins partiellement ouvert vers les enroulements (4) adjacents à la cale de fermeture (6).
