Ständer für elektrische Maschinen
Stand der Technik Stands for electrical machines
State of the art
Die Erfindung geht aus von einem Ständer für elektrische Maschinen
nach der Gattung des Hauptanspruchs. Bei bekannten
Ständerwicklungen ist das Profil des Drahtes rund, so daß sich stets ein Zwischenraum zwischen den Drähten ergibt. Das
hat den Nachteil, daß der Nutquerschnitt nicht optimal ausgefüllt ist. Man hat bei elektrischen Maschinen bereits Einzeldraht-Wicklungen
mit rechteckigen oder quadratischen Profilleitern verwendet (DE-AS 12 03 374), die den Füllfaktor
der Nuten erhöhen. Diese Lösungen sind jedoch sehr aufwendig, da die Leiter einzeln eingesetzt und verschaltet werden.
25The invention is based on a stator for electrical machines according to the type of the main claim. In known stator windings, the profile of the wire is round, so that there is always a gap between the wires. This has the disadvantage that the slot cross-section is not filled optimally. Single-wire windings with rectangular or square profile conductors have already been used in electrical machines (DE-AS 12 03 374), which increase the filling factor of the slots. However, these solutions are very complex, since the conductors are inserted and connected individually.

Vorteile der ErfindungAdvantages of the invention
Der erfindungsgemäße Ständer für elektrische Maschinen mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß die Raumausnutzung der Ständernut beim Einlegen ganzer Spulen verbessert ist. Damit wird auch der Wirkungsgrad des Generators erhöht. Auch hat sich gezeigt, daß bei besserer Raumausnutzung in der Nut die Nutverschlußnacharbeit wesentlich verringert wird. Ferner wird eine bessere Wärmeaabfuhr durch kleine Zwischenräume zurThe stator for electrical machines according to the invention with the characterizing features of the main claim has the advantage that the space utilization of the stator slot is improved when inserting entire coils. This also increases the efficiency of the generator. It has also been shown that with better space utilization in the slot, the slot closure rework is significantly reduced. Furthermore, better heat dissipation is achieved through small gaps.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung und in der nachfolgenden Beschreibung wiedergegeben. Die Zeichnung zeigt in Figur 1 einen Generator in perspektivischer Ansicht, in Figur 2 einen Ausschnitt eines Ständerpakets mit einer Nut für die Ständerwicklung.An embodiment of the invention is shown in the drawing and in the following description. The drawing shows a generator in perspective view in Figure 1, and a section of a stator core in Figure 2 with a groove for the stator winding.
Beschreibung des AusführungsbeispielsDescription of the embodiment
Bei der Maschine nach Figur 1 ist der grundsätzliche Aufbau eines Drehstrom-Klauenpol-Generators dargestellt. Mit 1 ist das Schleifringlagerschild bezeichnet, mit 2 der Gleichrichter und mit 3 eine Leistungsdiode des Gleichrichters. Weiterhin ist eine Erregerdiode 4 zu erkennen sowie Regler, Bürstenhalter und Kohlebürsten mit der Bezeichnung 5. Zu erkennen ist weiterhin der Ständer 6, der Läufer 7 sowie der Lüfter 8, die Riemenscheibe 9 und das Antriebslagerschild 10.The machine in Figure 1 shows the basic structure of a three-phase claw pole generator. 1 designates the slip ring bearing shield, 2 the rectifier and 3 a power diode of the rectifier. Furthermore, an excitation diode 4 can be seen as well as the regulator, brush holder and carbon brushes with the designation 5. Also visible are the stator 6, the rotor 7 as well as the fan 8, the pulley 9 and the drive bearing shield 10.
Die Figur 2 zeigt einen stark vergrößert dargestellten Ausschnitt aus dem Ständerpaket 6 und insbesondere den Querschnitt einer am Innenumfang des Bleckpaketes 6 axial verlaufenden Nut 12 für die Ständerwicklung 11. Sie ist seitlich verkleidet mit Isolationspapier 13 und an der Nutöffnung 15 mit Nutverschlußpapier 14 versehen. 30Figure 2 shows a greatly enlarged section of the stator core 6 and in particular the cross section of a slot 12 for the stator winding 11 that runs axially on the inner circumference of the laminated core 6. It is covered on the sides with insulation paper 13 and provided with slot sealing paper 14 at the slot opening 15. 30
Erfindungsgemäß besteht der Wicklungsdraht für die aus mehreren geschlossenen Windungen hergestellten Spulen der Ständerwicklung 11 aus einem Profildraht 16 mit Sechseck-Querschnitt, wobei in jeder Nut 12 möglichst viele Drähte 16 mit ihren Flachseiten 16a nahezu aneinanderliegen, so daß sichAccording to the invention, the winding wire for the coils of the stator winding 11, which are made up of several closed turns, consists of a profile wire 16 with a hexagonal cross-section, with as many wires 16 as possible lying almost against one another with their flat sides 16a in each slot 12, so that
R. 31664R.31664
keine oder keinen nennenswerten Zwischenräume ergeben. Damit erreicht man eine wesentlich bessere Nutfüllung gegenüber den üblichen Drähten mit kreisförmigem Querschnitt, bei denen sich immer Hohlräume zwischen denselben bilden. An den vorhandenen Wickelmaschinen sind keinerlei Änderungen gegenüber den bisherigen Drähten notwendig. Auch hat sich gezeigt, daß die Nutverschlußnacharbeit wesentlich gesenkt werden kann gegenüber bisherigen Ausführungen.no or no significant gaps are created. This achieves a much better slot filling than the usual wires with a circular cross-section, where cavities always form between them. No changes are necessary to the existing winding machines compared to the previous wires. It has also been shown that the slot closure rework can be significantly reduced compared to previous designs.
