Abstract[German]
Die Erfindung betrifft einen Rotor (1) für eine fremderregte Synchronmaschine (2) mit auf einer hohlen Rotorwelle (3) angeordneten Rotorwicklungen (4). Erfindungswesentlich ist dabei, - dass in der hohlen Rotorwelle (3) ein Drehtransformator-Rotor (7) mit einer Sekundärspule (8) und einem die Sekundärspule (8) zumindest bereichsweise umgebenden Ferritkern (9) angeordnet ist, - dass der Ferritkern (9) zumindest zwei separate Ringsegmente (10) mit zumindest zwei in Umfangsrichtung (27) dazwischen angeordneten und durchgehenden Spalten (11) aufweist, wobei sich die zumindest zwei Ringsegmente (10) an der Rotorwelle (3) abstützen.[English]
The invention relates to a rotor (1) for a separately excited synchronous machine (2), comprising rotor windings (4) disposed on a hollow rotor shaft (3). It is essential to the invention - that a rotary transformer rotor (7) having a secondary coil (8) and having a ferrite core (9) at least partly surrounding the secondary coil (8) is disposed in the hollow rotor shaft (3), - that the ferrite core (9) comprises at least two separate ring segments (10) with at least two continuous gaps (11) located between said ring segments in the circumferential direction (27), the at least two ring segments (10) being supported on the rotor shaft (3).[French]
L'invention concerne un rotor (1) pour une machine synchrone à excitation séparée (2), comprenant des enroulements de rotor (4) disposés sur un arbre de rotor creux (3). Selon l'invention, un rotor de transformateur rotatif (7) comprenant une bobine secondaire (8) et un noyau de ferrite (9) entourant au moins partiellement la bobine secondaire (8) est disposé dans l'arbre de rotor creux (3), le noyau de ferrite (9) comprend au moins deux segments annulaires séparés (10) avec au moins deux espaces continus (11) situés entre lesdits segments annulaires dans la direction circonférentielle (27), lesdits au moins deux segments annulaires (10) étant supportés sur l'arbre de rotor (3).
