Description
Statorwicklung und Verfahren zu ihrer HerstellungStator winding and method for its production
Die Erfindung betrifft eine Statorwicklung für eine elektrische Maschine, insbesondere für einen Elektromotor nach dem Oberbegriff von Anspruch 1. Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung einer Statorwicklung für eine elektrische Maschine, insbesondere einen Elektromotor nach dem Oberbegriff von Anspruch 7.The invention relates to a stator winding for an electric machine, in particular for an electric motor according to the preamble of claim 1. Furthermore, the invention relates to a method for producing a stator winding for an electrical machine, in particular an electric motor according to the preamble of claim. 7
Bei elektrischen Maschinen, insbesondere Elektromotoren wie beispielsweise bürstenlosen Elektromotoren ist ein Stator vorgesehen der innerhalb eines Rotors angeordnet ist und eine Mehrzahl von Wicklungen aufweist, die um Polschenkel des Wicklungsträgers verlaufen. Zur Herstellung derartiger Wicklungen wird zunächst mittels einer Verbindungseinrichtung ein Drahtende mit einer Anschlussfläche wie etwa einem Kontakthaken verbunden. Anschließend wird mit Hilfe eines Wickelkopfs die Ausbildung der eigentlichen Spulenwicklung um den Wicklungsträger herum verwirklicht.In electrical machines, in particular electric motors such as brushless electric motors, a stator is provided which is arranged within a rotor and has a plurality of windings which extend around the pole leg of the winding carrier. To produce such windings, a wire end is first connected by means of a connecting device to a connection surface, such as a contact hook. Subsequently, the formation of the actual coil winding is realized around the winding support around with the aid of a winding head.
Um das Wickeln der Statoren, der so genannten Lamellenpakete, zu ermöglichen, wird auf dem Wicklungsträger eine entsprechende Anzahl geeigneter Kontakthaken vorgesehen. Der Wickel- prozess selbst ist dabei nur dann möglich, wenn die Kontakthaken axial über den Wickelkopf überstehen. Ein derartiges Verfahren ist beispielsweise aus der DE 693 04 128 T2 bekannt. Weiterhin bekannt ist beispielsweise aus der DE 10 2004 012 925 Al, den Wickelprozess dadurch zu verbessern, dass die Polzähne vor dem Befüllen mit der Wicklung durch Krafteinwirkung in eine Befüllstellung gebogen werden. Nach dem Einbau werden die Polzähne wieder in die ursprüngliche Position gebracht.
Entsprechend der vorliegenden Erfindung wird nun vorgeschlagen, eine Statorwicklung zweiteilig auszugestalten, wobei der erste Teil durch einen Wicklungsträger und der zweite Teil durch ein Lamellenpaket realisiert werden. Der Wicklungsträ- ger und das Lamellenpaket sind dabei in ihren geometrischen Abmessungen und in ihrer Form so aufeinander abgestimmt, dass der Wicklungsträger und das Lamellenpaket vor dem Wickeln in einer definierten Wickelposition definiert zueinander positionierbar sind. Nach dem Wickeln der Statorwicklung können der Wicklungsträger und das Lamellenpaket ineinander verschoben werden .In order to allow the winding of the stators, the so-called disk packs, a corresponding number of suitable contact hooks is provided on the winding support. The winding process itself is only possible if the contact hooks protrude axially beyond the winding head. Such a method is known for example from DE 693 04 128 T2. It is furthermore known, for example, from DE 10 2004 012 925 A1 to improve the winding process by bending the pole teeth into a filling position before being filled with the winding by the application of force. After installation, the pole teeth are returned to their original position. According to the present invention, it is now proposed to design a stator winding in two parts, the first part being realized by a winding carrier and the second part by a disk pack. In this case, the winding carrier and the disk pack are matched to one another in terms of their geometric dimensions and in their shape such that the winding carrier and the disk pack can be positioned relative to one another before winding in a defined winding position. After winding the stator winding of the winding carrier and the disk pack can be moved into each other.
Mit der vorgeschlagenen Statorwicklung kann eine kompakte Bauweise des Motors erreicht werden.With the proposed stator winding, a compact design of the motor can be achieved.
In einer bevorzugten Ausführungsform der Erfindung wird das Lamellenpaket abgestuft ausgeführt. Korrespondierende Stufen können dabei zumindest abschnittsweise in dem Wicklungsträger vorgesehen werden.In a preferred embodiment of the invention, the disk pack is executed stepped. Corresponding steps can be provided at least in sections in the winding support.
Um den Wicklungsträger relativ zum Lamellenpaket in einer Wickelposition halten zu können, kann der Wicklungsträger eine Mehrzahl von Verlängerungsdomen aufweisen. Für diese Ausführungsform der Erfindung können in dem Lamellenpaket Ausspa- rungen vorgesehen werden, die so ausgeführt und angeordnet sind, dass sie zur Aufnahme der Verlängerungsdome geeignet sind. Dies gewährleistet zum einen eine definierte Position des Wicklungsträgers zum Lamellenpakt während des Wickeins und zum anderen die Möglichkeit, die Verlängerungsdome nach dem Wickeln in die Ausnehmungen einzuschieben, so dass damit eine axial kurze Bauweise ermöglicht wird.In order to be able to hold the winding carrier in a winding position relative to the disk pack, the winding carrier may have a plurality of extension domes. For this embodiment of the invention, recesses may be provided in the disk pack, which are designed and arranged so that they are suitable for receiving the extension dome. This ensures, on the one hand, a defined position of the winding carrier for the lamellae pact during winding and, on the other hand, the possibility of inserting the extension dome into the recesses after winding, so that an axially short construction is made possible.
Zur Herstellung einer Statorwicklung geht man erfindungsgemäß von einem Wicklungsträger und einem Lamellenpaket aus, das eine Mehrzahl von Polzähnen aufweist. Der Wicklungsträger und das Lamellenpaket werden vor dem Wickeln in einer Wickelposi-
tion zueinander positioniert. Nach dem Wickeln wird der Wicklungsträger in der Lamellenpaket hinein geschoben.To produce a stator winding, the invention is based on a winding carrier and a disk set having a plurality of pole teeth. The winding carrier and the disk pack are wound in a winding position before being wound. tion positioned to each other. After winding, the winding carrier is pushed into the disk pack.
Mit dieser Vorgehensweise ist es möglich, den axialen Bauraum zu reduzieren. Denn die axiale Ausdehnung der über den Wickelkopf hinaus stehenden Kontakthaken kann damit durch ein verschieben des Wicklungsträgers in das Lamellenpaket hinein deutlich verringert werden. Dies resultiert in einer spürbaren Reduzierung des Bauraums des Gesamtmotors.With this procedure, it is possible to reduce the axial space. Because the axial extent of standing beyond the winding head contact hook can thus be significantly reduced by a shift of the winding carrier into the disk set inside. This results in a noticeable reduction in the installation space of the entire engine.
Bevorzugt werden Verlängerungsdome, die an dem Wicklungsträger vorgesehen sind, nach dem Wickeln in entsprechende Ausnehmungen im Lamellenpaket eingeschoben. Damit kann ein Reduzierung der Ausdehnung von beispielsweise 2 bis 10 mm, insbe- sondere von 6 mm erreicht werden.Preferably extension dome, which are provided on the winding support, inserted after winding into corresponding recesses in the disk set. Thus, a reduction in the extent of, for example, 2 to 10 mm, in particular of 6 mm can be achieved.
Die Erfindung hat weiterhin den Vorteil, dass zusätzlich zur kompakten Bauweise des Motors, die erreicht werden kann, Material eingespart werden kann. So kann gleichzeitig auch eine Kostenreduzierung erreicht werden.The invention also has the advantage that, in addition to the compact design of the engine, which can be achieved, material can be saved. Thus, a cost reduction can be achieved at the same time.

Fig. 1 zeigt in einer Skizze das Wickeln einer Statorwicklung nach dem Stand der Technik. Um das Wickeln der Statorwicklung zu ermöglichen wird ein Wicklungsträger 12 mit geeigneten Kontaktblechen, beispielsweise mit Kontakthaken 22 versehen. An den Kontakthaken 22 wird der Wickeldraht 26 befestigt. Die Kontakthaken 22 müssen jedoch, um einen Wickelprozess mit dem Wickelkopf 24 zu ermöglichen, axial über den Wickelkopf 24 überstehen. Wie aus Fig. 1 zu entnehmen ist, bedingt das Ein- hängen der Wickeldrähte 26 einen axialen Überstand von mehreren Millimetern, über den Wickelkopf 24, der im dargestellten Beispiel 7 mm beträgt. Dies geht zu Lasten der Baulänge des Motors, so dass dieser axial länger baut.Fig. 1 shows in a sketch the winding of a stator winding according to the prior art. In order to enable the winding of the stator winding, a winding support 12 is provided with suitable contact plates, for example with contact hooks 22. At the contact hook 22 of the winding wire 26 is attached. However, the contact hooks 22 must, in order to enable a winding process with the winding head 24, protrude axially beyond the winding head 24. As can be seen from FIG. 1, the hooking of the winding wires 26 causes an axial projection of several millimeters, over the winding head 24, which in the example illustrated is 7 mm. This is at the expense of the length of the engine so that it builds axially longer.
Fig. 2 zeigt in einer perspektivischen Darstellung einen erfindungsgemäßen Wicklungsträger 12 mit Kontakthaken 22. An den Kontakthaken 22 müssen die Wickeldrähte 26 vor dem Beginn der Wicklung befestigt werden. Nachdem die Wickeldrähte 26 an den Kontakthaken 22 befestigt sind, kann damit begonnen wer- den, mit einem Wickelkopf 24 (Fig. 1) den Wickeldraht 26 zu Lamellendrahtpaketen 28 (Fig. 5, Fig. 6) zu wickeln.2 shows a perspective view of a winding support 12 according to the invention with contact hooks 22. At the contact hooks 22, the winding wires 26 have to be fastened before the beginning of the winding. After the winding wires 26 are fastened to the contact hooks 22, it is possible to start winding winding wire 26 with a winding head 24 (FIG. 1) to form lamination wire packages 28 (FIGS. 5, 6).
Nach der Erfindung wird hierzu vorgeschlagen, einen Wickelträger 12 und ein Lamellenpaket 14 zu verwenden, die bei- spielhaft in Fig. 3 perspektivisch dargestellt sind. Das Lamellenpaket 14 (Fig. 3b) weist eine Mehrzahl von Polzähnen 20 auf, die während des Wickeins so umwickelt werden, dass La- mellendrahtpakete 28 (Fig. 6) entstehen. Das Lamellenpaket 14 ist mit Vertiefungen 30 versehen, in die korrespondierende Überstände 32 des Wicklungsträgers 12 (Fig. 3a) dann zum Liegen kommen können, wenn der Wicklungsträgers 12 mit dem Lamellenpaket 14 geeignet zusammengefügt wird. Weiterhin sind
im Lamellenpaket 14 Ausnehmungen 18 vorgesehen. Die Ausnehmungen 18 sind so ausgeführt und angeordnet, dass sie zur Aufnahme von Gegenstücken geeignet sind, die am Wicklungsträger 12 vorgesehen sind. Damit können in die Ausnehmungen 18 korrespondierende Gegenstücke des Wicklungsträgers 12 eingreifen, sobald der Wicklungsträger 12 mit dem Lamellenpaket 14 geeignet zusammengefügt wird. Zu diesem Zweck können am Wicklungsträger 12 beispielsweise Verlängerungsdome 16 vorgesehen werden, die so dimensioniert sind, dass sie durch die Ausnehmungen 18 gedrückt werden können. Die Verlängerungsdome 16 werden dabei so ausgestaltet, dass sie den Wicklungsträger 12 vor der Durchführung des Wickelvorgangs in einer Wickelposition halten können. Im Lamellenpaket können auch Öffnungen 19 für Spannpratzen vorgesehen sein, die zur Befestigung des Lamellenpakets beim Wickelprozess dienen.According to the invention for this purpose, it is proposed to use a winding support 12 and a plate pack 14, which are exemplified in perspective in Fig. 3. The lamination stack 14 (FIG. 3 b) has a plurality of pole teeth 20, which are wound during winding in such a way that lamellae wire packages 28 (FIG. 6) are formed. The disk set 14 is provided with depressions 30 into which corresponding projections 32 of the winding carrier 12 (FIG. 3 a) can then come to rest when the winding carrier 12 is joined together in a suitable manner with the disk set 14. Furthermore are provided in the disk pack 14 recesses 18. The recesses 18 are designed and arranged so that they are suitable for receiving counterparts, which are provided on the winding support 12. In order for 18 corresponding counterparts of the winding support 12 can engage in the recesses, as soon as the winding support 12 is suitably joined together with the plate pack 14. For this purpose, for example extension dome 16 can be provided on the winding support 12, which are dimensioned so that they can be pressed through the recesses 18. The extension dome 16 are designed so that they can hold the bobbin 12 before performing the winding process in a winding position. Openings 19 for clamping claws can also be provided in the disk pack, which openings serve for fastening the disk pack during the winding process.
Anhand der Fig. 4 und 5 wird das Verfahren zur Herstellung der Statorwicklung erläutert. Dabei zeigt Fig. 4 die relative Position des Wicklungsträgers 12 zum Lamellenpaket 14 in der so genannten Wickelposition, in der Position also, in der die Lamellendrahtpakete 28 (Fig. 5) gewickelt werden. Dabei ist der Wicklungsträger 12 relativ zum Lamellenpaket 14 so positioniert, dass die Kontakthaken 22 mit ihrer, dem Lamellenpaket 14 zugewandten Fläche, überstehen. Im gezeigten Beispiel beträgt dieser Überstand 12 mm. Da das Lamellenpaket 14 gestuft ausgeführt ist, können die Verlängerungsdome 16 den Wicklungsträger 12 in Wickelposition halten. Wird so vorgegangen, so ist dass das Wickeln mit einem Wickelkopf auf einfache Weise möglich.The method for producing the stator winding will be explained with reference to FIGS. 4 and 5. 4 shows the relative position of the winding carrier 12 to the disk set 14 in the so-called winding position, ie in the position in which the laminated wire packages 28 (FIG. 5) are wound. In this case, the winding support 12 is positioned relative to the disk pack 14 so that the contact hooks 22 with their, the disk pack 14 facing surface, survive. In the example shown, this supernatant is 12 mm. Since the disk set 14 is designed stepped, the extension dome 16 can hold the winding support 12 in winding position. If this is the case, then winding with a winding head is possible in a simple manner.
Nach dem Wickeln wird der Wicklungsträger 12, in Richtung des Lamellenpakets 14 verschoben, bis die Verlängerungsdome 16 durch die Ausnehmungen 18 des Lamellenpakets 14 getaucht sind. Die relative Position des Lamellenpakets 14 Wicklungs- träger 12 ist in Fig. 5 gezeigt. Im dargestellten Beispiel kann mit dieser Vorgehensweise eine Bauraumreduzierung um 6 mm erreicht werden, da der Abstand des Wicklungsträgers 12
relativ zum Lamellenpaket 14 durch das Ineinanderschieben um 6 mm verringert werden kann. Die Kontakthaken 22 stehen dann mit ihrer, dem Lamellenpaket 14 zugewandten Fläche über. Im gezeigten Beispiel beträgt der Überstand 6 mm. Typischerweise lassen sich allerdings mit dieser Vorgehensweise Bauraumeinsparungen im Bereich von 2 bis 10 mm realisieren.After winding, the winding support 12 is displaced in the direction of the disk set 14 until the extension domes 16 are immersed through the recesses 18 of the disk set 14. The relative position of the laminated core 14 winding support 12 is shown in FIG. In the illustrated example, a space reduction of 6 mm can be achieved with this approach, since the distance of the winding support 12th relative to the disk pack 14 can be reduced by the telescoping by 6 mm. The contact hooks 22 then stand with their, the disk pack 14 facing surface over. In the example shown, the supernatant is 6 mm. Typically, however, with this procedure space savings in the range of 2 to 10 mm can be realized.
Fig. 6 zeigt eine perspektivische Darstellung einer fertig gewickelten Statorwicklung 10. Die Statorwicklung 10 weist den Wicklungsträger 12 und das Lamellenpaket 14 auf, die nun ineinander geschoben sind. In der zusammengebauten Statorwicklung 10 ragen die Verlängerungsdome 16 heraus. Diese sind jedoch in ihrer Dimensionierung so gehalten, dass sie beim weiteren Einbau in den Motor auf einfache Weise in entspre- chende Gegenstücke eintauchen können.Fig. 6 shows a perspective view of a finished wound stator winding 10. The stator winding 10 has the winding support 12 and the disk set 14, which are now pushed into one another. In the assembled stator winding 10, the extension dome 16 protrude. However, these are dimensioned in such a way that they can easily submerge into corresponding counterparts on further installation in the engine.
Die beschriebene Statorwicklung 10 kann insbesondere in EC- Außenläufermotoren eingesetzt werden. Beispielsweise können solche Motoren in Heiz- oder Kühlgebläsen Verwendung finden. Insbesondere bei solchen Einsatzgebieten wirken sich die erfindungsgemäßen Vorteile eines kurzen axialen Bauraums und der bereits angeführten Materialeinsparung positiv aus.
The described stator winding 10 can be used in particular in EC external rotor motors. For example, such motors can be used in heating or cooling fans. In particular, in such applications, the advantages of the invention a short axial space and the already mentioned material savings have a positive effect.
