Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung einer Statorwicklung einer elektrischen Maschine gemäß dem Oberbegriff des Patentanspruchs 1, sowie eine elektrische Maschine mit einer entsprechend hergestellten Statorwicklung gemäß dem Oberbegriff des Patentanspruches 7.The The invention relates to a method for producing a stator winding an electric machine according to the preamble of claim 1, as well as an electric machine with a According manufactured stator winding according to the preamble of claim 7th
Elektrische Maschinen, auf die im Folgenden Bezug genommen wird, umfassen einen Stator, der aus mehreren ringförmig angeordneten Einzelpolen zusammengesetzt ist. Die Einzelpole bestehen jeweils aus einem so genannten Wickelzahn, auf dem Draht aufgewickelt ist. Im Betrieb der elektrischen Maschine werden die einzelnen Wicklungen bestromt und erzeugen dadurch einen Beitrag zu einem sich drehenden magnetischen Feld. Für die Leistungsfähigkeit des Elektromotors ist es von wesentlicher Bedeutung, dass die Wicklungen möglichst dicht gewickelt sind, d.h. eine möglichst hohe Fülldichte aufweisen. Im Grunde gilt: je höher die Fülldichte, desto höher die Leistungsfähigkeit der Maschine.electrical Machines referred to below include one Stator made up of several annular arranged individual poles is composed. The single poles exist each from a so-called winding tooth, wound on the wire is. During operation of the electric machine, the individual windings energized and thereby generate a contribution to a rotating magnetic field. For the efficiency Of the electric motor, it is essential that the windings as close as possible are wound, i. one possible high filling density exhibit. Basically, the higher the filling density, the higher the efficiency the machine.
Um eine hohe Fülldichte zu erreichen, ist es bekannt, den Draht in einer Wickelstation zunächst auf den Wickelzahn zu wickeln und danach mechanisch zu pressen. Dadurch wird zwar gegenüber einer nicht gepressten Wicklung eine höhere Fülldichte erreicht, nach dem Lösen der Pressbacken federt der Draht jedoch wieder geringfügig in seine Ausgangslage zurück, so dass die hohe Fülldichte nicht dauerhaft erhalten bleibt.Around a high filling density It is known to reach the wire in a winding station first Wind the winding tooth and then press it mechanically. Thereby is indeed opposite a non-pressed winding reaches a higher filling density, after the Solve the Pressing jaws the wire but again slightly in his Starting position back, so the high filling density not permanently preserved.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren zur Herstellung einer elektrischen Maschine bzw. deren Statorwicklung zu schaffen, mittels dessen die Fülldichte der Wicklung weiter erhöht werden kann.It is therefore an object of the present invention, a method for Production of an electrical machine or its stator winding to provide, by means of which the filling density of the winding can be further increased can.
Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Patentanspruch 1, sowie im Patentanspruch 7 angegebenen Merkmale. Weitere Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen.Is solved this task according to the invention by the in claim 1, and in claim 7 specified Characteristics. Further embodiments of the invention are the subject of dependent claims.
Ein wesentlicher Aspekt der Erfindung besteht darin, bei der Herstellung der Statorwicklung einen Draht zu verwenden, der mit einem Haftmittel versehen ist. Dadurch haften benachbarten Drahtstücke einer Wicklung beim Pressen, wenn sie miteinander in Kontakt kommen, aneinander und bleiben auch nach dem Lösen der Pressbacken in diesem Zustand. Die Fülldichte eines Einzelpols kann somit weiter erhöht werden. Darüber hinaus ist es nun möglich, einige Windungen mehr als bisher auf denselben Wickelzahn zu wickeln und somit die Induktivität der Wicklung zu erhöhen.One essential aspect of the invention is in the production the stator winding to use a wire, which provided with an adhesive is. As a result, adjacent pieces of wire adhere to a winding during pressing, when they come into contact with each other, together and stay behind the release the pressing jaws in this state. The filling density of a single pole can thus further increased become. About that it is now possible Wind a few turns more than before on the same winding tooth and thus the inductance to increase the winding.
Gemäß einer bevorzugten Ausführungsform der Erfindung wird für die Wicklung ein Draht verwendet, der mit einem so genannten Back-Lack versehen ist. Diese Art von Lack schmilzt, wenn der Draht erhitzt wird und bildet eine feste Verbindung, wenn der Draht wieder abkühlt. Bei der Herstellung der Statorwicklung wird der Draht daher zunächst erhitzt und vorzugsweise noch im gepressten Zustand wieder abgekühlt, so dass der Back-Lack eine feste Verbindung zwischen den einzelnen Leiterschleifen herstellt.According to one preferred embodiment of Invention is for The winding uses a wire that has a so-called baking varnish is provided. This type of paint melts when the wire is heated and forms a tight connection when the wire cools down again. at Therefore, the wire is first heated in the production of the stator winding and preferably cooled down again in the pressed state, then that the baking varnish is a firm connection between the individual Produces conductor loops.
Zum Erhitzen des Drahtes wird dieser vorzugsweise bestromt. Der Draht erwärmt sich dabei durch die eigene ohmsche Verlustleistung. Dies ermöglicht eine gleichmäßige Erhitzung des Drahtes entlang seines Umfangs, so dass nach allen Seiten eine gleichmäßige Haftwirkung erzielt wird. Dies äußert sich insbesondere in gleichmäßigen Abständen zu benachbart angeordneten Drahtabschnitten.To the Heating the wire, this is preferably energized. The wire heated thereby by its own ohmic power loss. This allows a uniform heating of the wire along its circumference, so that on all sides one uniform adhesive effect is achieved. This manifests itself especially at regular intervals adjacent wire sections.
Alternativ können natürlich auch andere Haftmittel verwendet werden.alternative can Naturally also other adhesives are used.
Die Presskraft beträgt vorzugsweise zwischen 2 bar und 6 bar und liegt insbesondere etwa bei 4 bar. Dadurch können sich insbesondere bestimmte, vom Haftmittel abhängige Schichtdicken des Haftmittels ergeben. Die Presskraft ist vorzugsweise so gewählt, dass einerseits die Schichtdicke möglichst gering ist, um einen hohen Füllgrad zu erzielen, andererseits um – insbesondere bei nicht isolierten Drähten – eine ausreichende Isolationswirkung zu benachbarten Wicklungen zu erzielen.The Pressing force amounts preferably between 2 bar and 6 bar and is especially at about 4 bar. Thereby can in particular certain, dependent on the adhesive layer thicknesses of the adhesive result. The pressing force is preferably chosen so that on the one hand the layer thickness as possible is low to a high degree of filling on the other hand, in particular for non-insulated wires - a sufficient Isolation effect to achieve adjacent windings.
Der Wickeldraht ist vorzugsweise ein Cu-Lackdraht.Of the Winding wire is preferably a copper enameled wire.
