Die
Erfindung geht aus von einem Verfahren zur Herstellung einer Wicklung
für den Stator einer elektrischen Maschine, insbesondere
eines Drehstromgenerators für Kraftfahrzeuge, wie es beispielsweise
aus der
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Verfahren mit den Merkmalen des unabhängigen Anspruchs hat den Vorteil, dass sich die einzelnen Spulenseiten der Wicklung mit hohem Füllfaktor ohne Schwierigkeiten in die Nuten des Stators einfügen lassen unter Vermeidung von Drahtkreuzungen und querschnittsverengenden Drahtquetschungen. Die Form des vorgeformten, geprägten Nutpaketes bleibt nach dem Herausnehmen aus der Prägeform weitgehend erhalten, so dass das Drahtpaket einer Spulenseite präzise in jeweils eine Nut eingebracht werden kann. Weiterhin wird bei dieser Art der Formgebung des Wicklungsstrangs auch die Isolation der einzelnen Wicklungsdrähte gering belastet und die Drahtisolation nicht beschädigt.The inventive method with the features of independent claim has the advantage that the individual Coil sides of the winding with high filling factor without difficulty in insert the slots of the stator while avoiding of wire crossings and cross-section narrowing wire crimping. The shape of the preformed, embossed groove package remains largely retained after removal from the stamping mold, so that the wire package a coil side precisely in each case a groove can be inserted. Furthermore, in this Art the shape of the winding strand and the isolation of the individual Winding wires lightly loaded and the wire insulation not damaged.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im unabhängigen Anspruch angegebenen Verfahrens möglich. Besonders vorteilhaft ist es hierbei, dass neben der getrennten Prägung der einzelnen Spulenseiten auch jeder Wicklungsstrang getrennt geprägt und einzeln in die Nuten des Stators eingebracht werden kann. Neben der Vereinfachung und Verbilligung des Prägewerkzeugs wird hierdurch das Einfügen der Wicklung in die Statornuten deutlich erleichtert, da die Wicklungsstränge mit geringen Fertigungstoleranzen einzeln in die Nuten des Stators eingebracht werden können.By those listed in the dependent claims Measures are advantageous developments and improvements of the method specified in the independent claim possible. It is particularly advantageous that in addition to the separate Embossing of the individual coil sides also each winding strand shaped separately and introduced individually into the grooves of the stator can be. In addition to the simplification and cheapening of the embossing tool This is the insertion of the winding in the stator slots much easier, since the winding strands with low Manufacturing tolerances individually introduced into the grooves of the stator can be.
Hinsichtlich der Gestaltung des Prägewerkzeuges ist es vorteilhaft, wenn die für jeweils eine Nut bestimmten Spulenseiten eines Wicklungsstrangs gemeinsam in einer nutartig gestalteten Schablone mit parallelen, seitlich verschiebbaren Flanken vorgeformt werden. Mit einer derartigen Schablone erhält man eine nach dem Prägen sehr gut an die Gestalt der Nuten angepasste Form der Spulenseiten, welche auch nur eine geringe Tendenz zur Aufweitung nach der Entnahme aus dem Prägewerkzeug besitzen. Durch parallele, seitlich verschiebbare Flanken an den Schablonen wird die Entnahme der geprägten Spulenseiten deutlich erleichtert und Verformungen beim Herausnehmen der Spulenseite aus dem Prägewerkzeug praktisch vollständig vermieden. Die Spulenseiten eines Wicklungsstrangs werden hierbei vorzugsweise gemeinsam durch einen Prägestempel in den Schablonen auf der gesamten Länge der Nut geprägt, während der ursprüngliche Drahtquerschnitt in den Bereichen außerhalb der Nut erhalten bleibt, sodass die Gestaltungsmöglichkeiten der Wickelköpfe der Wicklung unbeeinflusst bleiben.Regarding the design of the embossing tool, it is advantageous if the coil sides of a Wicklungsstrangs together in a groove-like template with parallel, laterally movable flanks are preformed. With Such a template is obtained after embossing very well adapted to the shape of the grooves shape of the coil sides, which even a slight tendency for expansion after removal own the embossing tool. By parallel, laterally movable flanks on the templates is the removal of the embossed coil sides much easier and deformation when removing the coil side almost completely avoided from the stamping tool. The coil sides of a winding strand are in this case preferably together by an embossing stamp in the templates the entire length of the groove is shaped while the original wire cross section in the areas outside the groove is preserved, so that the design options of Winding heads of the winding remain unaffected.
Als besonders vorteilhaft hat es sich erwiesen, wenn die Leiter der Spulenseiten beim Prägen der Wicklung übereinander angeordnet werden. Hierdurch wird das Prägen der Spulen besonders erleichtert, das Aufspringen der Spulenseiten nach der Entnahme aus der Prägeform minimiert und das Prägewerkzeug stark vereinfacht. Vorzugsweise sind die Drahtquerschnitte aller in der Wicklung verwendeten Drähte vor dem Prägen kreisförmig und gleich groß und die Breite der zum Prägen verwendeten Schablone etwas größer als der Drahtdurchmesser, jedoch kleiner als der doppelte Drahtdurchmesser. Hierdurch erreicht man, dass die Drähte einerseits leicht in die Schablone eingebracht werden können, andererseits jedoch Drahtkreuzungen und starke Verformungen der Drähte vermieden werden. Die Querschnittsfläche der Prägeschablone ist dabei zweckmäßigerweise kleiner als die in der Nut für die Spulenseite zur Verfügung stehende Querschnittsfläche, sodass elastische Rückverformungen der Spulenseite nach der Entnahme aus dem Prägewerkzeug das Einbringen der Wicklung in die Nut nicht behindert.When It has proved to be particularly advantageous if the conductors of the Coil sides when embossing the winding on top of each other to be ordered. This will cause the embossing of the coils especially relieved, the popping of the coil sides after the Removal from the stamping mold minimizes and the stamping tool greatly simplified. Preferably, the wire cross sections of all wires used in the winding before embossing circular and the same size and the width of the stencil used for embossing slightly larger as the wire diameter, but smaller than twice the wire diameter. This ensures that the wires on the one hand easily in the template can be introduced, on the other hand, however Wire intersections and strong deformations of the wires avoided become. The cross-sectional area of the embossing template is expediently smaller than the in the groove for the coil side available Cross-sectional area, so elastic rebounding the coil side after removal from the stamping tool the introduction of the winding in the groove is not hindered.
