Läuferkörper für elektrische Maschinen, insbesondere Turbogeneratoren Rotor bodies for electrical machines, in particular turbo generators

Bei elektrischen Maschinen, insbesondere Turbogeneratoren, ist die Erregerwicklung im Läufer über die geraden Abschnitte der Wicklung in Nuten eingebettet, die in den Ballenteil des Läufers eingefräst sind, während die Wickelköpfe außerhalb des Ballenteils auf einem Läuferkörperabschnitt geringeren Durchmessers festgelegt und von übergeschobenen Kappenringen gegen die auftretenden Fliehkräfte gehalten sind. Ein derartiger Läufer ist beispielsweise in der DT-OS 2 102 126 gezeigt.In electrical machines, especially turbo generators, the field winding in the rotor is via the straight sections of the Winding embedded in grooves that are milled into the ball part of the rotor, while the winding heads are outside the ball part on a rotor body section of smaller diameter are set and held by pushed-over cap rings against the centrifugal forces that occur. One such runner is for example shown in DT-OS 2 102 126.

Bei Läufern mit einer supraleitenden Erregerwicklung ist diese Art der Festlegung der Wicklung, insbesondere im Wickelkopfbereich, wegen der auftretenden Kräfte nicht mehr ausreichend. Der Erfindung liegt daher die Aufgabe zugrunde, einen Läuferkörper zur Aufnahme einer supraleitenden Erregerwicklung zu schaffen, der einfach ausgebildet ist und eine optimale Festlegung der Wicklung gestattet.In the case of rotors with a superconducting excitation winding, this type of fixing of the winding, especially in the winding head area, is no longer sufficient because of the forces involved. The invention is therefore based on the object of a rotor body to accommodate a superconducting excitation winding, which is simple and an optimal definition the winding allowed.

Zur Lösung dieser Aufgabe ist daher erfindungsgemäß vorgesehen, daß der Läuferkörper aus einem sich über die gesamte Wicklungslänge mit gleichmäßigem Durchmesser erstreckenden Zylinder besteht, in dessen Mantelfläche Wicklungsnuten entsprechend dem Spulenverlauf fortlaufend für den geraden Wicklungsteil und den Wickelkopfteil eingefräst sind. Durch diese Lösung ergibt sich auch im Wickelkopf eine gleich gute Befestigung der Wicklung wie im Ballenbereich.To solve this problem it is therefore provided according to the invention that the rotor body consists of a cylinder that extends over the entire length of the winding with a uniform diameter, in its outer surface winding grooves according to the course of the coil continuously for the straight winding part and the Winding head part are milled. This solution results Also in the winding head an equally good fastening of the winding as in the ball area.

Anhand einer stark schematisierten Zeichnung ist das Prinzip eines Ausführungsbeispiels nach der Erfindung näher erläutert.The principle is based on a highly schematic drawing an embodiment according to the invention explained in more detail.

Der Läuferkörper besteht aus einem Hohlzylinder 1, der sich über die gesamte Wicklungslänge - also auch über den Bereich derThe rotor body consists of a hollow cylinder 1, which extends over the entire winding length - including over the area of the

Wickelkopfe - mit gleichmäßigem Durchmesser erstreckt. In die Mantelfläche 2 dieses Zylinders 1 sind nunmehr nach der Erfindung die Wicklungsnuten 3 entsprechend dem Spulenverlauf, beispielsweise im Kopierfräsverfahren, in den Läuferkörper eingearbeitet. Es ergibt sich somit für jede Spule eine geschlossene umlaufende Nut, die sowohl die geraden, achsparallelen Nutabschnitte 4- als auch die in Umfangsrichtung verlaufenden Nutabschnitte 5 für den Wickelkopfbogen umfaßt. Damit können die einzelnen, nicht näher dargestellten konzentrischen Spulen als Ganzes in die jeweilige Nut eingelegt oder als Teilleiter eingewickelt werden.Winding heads - extending with a uniform diameter. In the Outer surface 2 of this cylinder 1 are now according to the invention the winding grooves 3 are incorporated into the rotor body in accordance with the course of the coil, for example using the copy milling process. This results in a closed circumferential groove for each coil, which has both the straight, axially parallel groove sections 4- as well as the groove sections running in the circumferential direction 5 includes for the winding head bow. This allows the individual, not shown concentric coils as The whole can be inserted into the respective groove or wrapped as a partial conductor.

Zur Halterung der Wicklung im Läuferkörper ist es dabei zweckmäßig, wenn neben herkömmlichen Nutverschlußkeilen in den geraden Wicklungsabschnitten, die im Spulenbogen 5 durch ein Füllstück aus Stahl ersetzt werden können, über den gesamten, mit der Wicklung versehenen Läuferkörper 1 ein strichpunktiert angedeuteter Stützzylinder 6 aufgeschrumpft wird, der sich ebenfalls über die gesamte Länge der Wicklung bzw. des Zylinders erstreckt und die eigentliche Wicklungsabstützung übernimmt.To hold the winding in the rotor body, it is useful to if in addition to conventional slot wedges in the straight winding sections, those in the coil arc 5 by a filler piece made of steel can be replaced, over the entire rotor body 1 provided with the winding, a dash-dotted line Support cylinder 6 is shrunk, which is also Extends over the entire length of the winding or the cylinder and takes over the actual winding support.

Voraussetzung für eine derartige Läuferkörperausbildung ist allerdings eine Übereinstimmung des Wärmedehnungsverhaltens der Wicklung mit dem Läuferkörper über den auftretenden Temperaturbereich. A prerequisite for such a rotor body training is however, the thermal expansion behavior of the winding and the rotor body must match over the temperature range that occurs.

Mit der beschriebenen Ausbildung des Läuferkörpers ist also eine optimale Halterung einer supraleitenden Erregerwicklung, insbesondere auch im Wickelkopfbereich möglich, wobei die bisher üblichen gesonderten Wickelkopfabstützungen und Versteifungen sowie die Kappenringe entfallen können.With the described design of the rotor body is so an optimal mounting of a superconducting excitation winding, in particular also in the winding head area, possible, with the previous customary separate winding head supports and stiffeners as well as the cap rings can be omitted.
