Die Erfindung bezieht sich auf eine Vorrichtung gemäß dem Oberbegriff des Patentanspruchs. Eine derartige Vorrichtung ist aus der CH-PS 3 59 477 bekannt.The invention relates to a device according to the preamble of the claim. Such a device is from CH-PS 3 59 477 known.
Zum Schutz der Wicklungen einer elektrischen Maschine gegen Beschädigungen beispielsweise durch das Blechpaket ist es aus der CH-PS 3 59 477 bekannt, in die Nuten zwischen den Nutwänden und der Wicklung Isolierhülsen aus unmagnetischem, elektrisch nichtleitendem Material einzulegen. Jede Isolierhülse steht dabei über die seitlichen Begrenzungsflächen des Statorblechpaketes hervor. Dieser Oberstand ist jedoch nicht störend, da die Wickelkopf noch weiter über das Ständerblechpaket hervorstehen.To protect the windings of an electrical machine against damage, for example by the laminated core is known from CH-PS 3 59 477, in The grooves between the groove walls and the winding are made of non-magnetic, electrically non-conductive insulating sleeves Insert material. Each insulating sleeve stands over the lateral boundary surfaces of the Stator laminated core. However, this overhang is not disturbing, as the winding head continues over the Stator core protrude.
Demgegenüber besteht die At 'gäbe der Erfindung darin, eine Vorrichtung der eingangs erwähnten Art dahingehend zu verbessern, daß der Überstand der Wickelköpfe über das Ständerblechpaket verringert und damit die Gesamtbreite der elektrischen Maschine *o geringer ist.In contrast, there is the at 'would give the invention is to improve a device of the type mentioned in that the overhang of the Winding heads are reduced over the stator core and thus the overall width of the electrical machine * o is less.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs gelöstAccording to the invention, this object is achieved by the characterizing features of the claim
Die Erfindung wird nachstehend anhand der Zeichnungen näher erläutert Es zeigenThe invention is explained in more detail below with reference to the drawings
Fig.I und 3 ausschnittsweise Draufsichten in der Horizontalebene auf jeweils eine Ausführungsform eines Ständers eines Langstatormotors, undFig.I and 3 partial plan views in the Horizontal plane on in each case one embodiment of a stator of a long stator motor, and
Pig.2 und 4 Längsschnitte in der Vertikalebene durch die Ständerausführungen nach F i g. 1 und 3 längs der Schnittlinien V-V bzw. VII-VII.Pig. 2 and 4 longitudinal sections in the vertical plane due to the stand designs according to FIG. 1 and 3 along the section lines V-V and VII-VII, respectively.
Die in den F i g. 1 und 3 in der Draufsicht und in den Fig.2 bzw. 4 im Schnitt dargestellten Ausschnitte aus zwei Ausführungsformen des Ständers 1 zeigen das geschichtete Blechpaket 2 und zwei Nuten 4, in welche jeweils ein Leiter 25 der Wicklung eingelegt ist Zur Verkürzung des Oberstands der Wickelköpfe über die beiden Längsseiten des Blechpakets 2 sind die Ansatzstellen für die wickelkopfbildenden Krümmungen der Leiter 25 nicht erst außerhalb der Nuten 4, sondern innerhalb der Nuten 4 vorgesehen. Diese Maßnahme bedingt, daß die Breitenabmessung der Nuten 4 wesentlich größer als der Leiterdurchmesser ist und der Raum zwischen den Nutenwänden und den Leitern 25 durch ein- oder mehrteilige Abfütterungen 26 ausgefüllt wird. Die Abfütterungen 26 bestehen aus unmagnetischem, elektrisch nicht-leitendem Material und sind vorzugsweise so vorgefertigt, daß ihre Form den Nuten 4 und den darin liegenden Leitern 25 angepaßt ist Femer stehen die Abfütterungen 26 über die Seitenwände des Blechpakets 2 um einen kleinen Betrag über, damit eine Berührung bzw. Beschädigung dei Leiter 25 an den Ecken der Nuten 4 vermieden wird. Im Falle der Ausführungsform nach F i g. 1 und 2 liegen die Abfütterungen 26 seitlich und unterhalb der LeiterThe in the F i g. 1 and 3 in plan view and in Fig. 2 and 4 in sections shown in sections two embodiments of the stator 1 show the laminated core 2 and two grooves 4 in which In each case a conductor 25 of the winding is inserted both long sides of the laminated core 2 are the starting points for the curvatures forming the winding head the conductor 25 is not provided outside of the grooves 4, but rather inside the grooves 4. These Measure requires that the width dimension of the grooves 4 is significantly larger than the conductor diameter and the space between the groove walls and the ladders 25 by one-part or multi-part linings 26 is filled out. The linings 26 are made of non-magnetic, electrically non-conductive material and are preferably prefabricated in such a way that their shape corresponds to the grooves 4 and the conductors 25 located therein is adapted Furthermore, the linings 26 are on the side walls of the laminated core 2 by a small amount Amount above, so that contact or damage to the conductor 25 at the corners of the grooves 4 is avoided. In the case of the embodiment according to FIG. 1 and 2 are the linings 26 to the side and below the ladder
25 und übernehmen somit gleichzeitig auch die Funktion des Glimmschutzes. Dagegen liegen im Falle der Ausführungsform nach F i g. 3 und 4 die Abfütterungen25 and thus also take on the function of corona protection at the same time. On the other hand, in the case of Embodiment according to FIG. 3 and 4 the feeding
26 oberhalb der Leiter 25. Diese Ausführungsform ist für flexible Leiter 25 vorteilhaft da die Abdeckungen über die vorstehenden Abfütterungen 26 die Leiter 25 auf der ganzen Blechpaketbreite in die Nuten 4 drücken.26 above the ladder 25. This embodiment is for Flexible conductors 25 advantageous because the covers over the protruding linings 26, the conductors 25 on the Press the entire width of the laminated core into the grooves 4.
Alternativ zu den Ausführungsformen nach F i g. 1 bis 4 können die Abfütterungen 26 auch die Leiter 25 allseitig umschließen, wobei sk selbstverständlich geteilt auszuführen sind.As an alternative to the embodiments according to FIG. 1 to 4, the linings 26 can also use the ladder 25 Enclose on all sides, whereby sk are of course to be carried out divided.
