Description
Die Erfindung betrifft eine elektrische Maschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to an electrical machine according to the Preamble of claim 1.
Eine solche Maschine ist durch die EP-A-0 357 913 bekannt. Bei dieser Maschine ist der Gehäusekörper im Schleudergußver fahren hergestellt. Mit einem solchen Verfahren lassen sich praktisch nur rotationssymmetrische Körper herstellen. Dies hat zur Folge, daß nach radial außen von dem Gehäuse abste hende, unregelmäßig geformte Teile, wie beispielsweise der Klemmenkasten oder die Füße der Maschine gesondert am Ge häuse angebracht werden müssen. Ein weiterer Nachteil ist, daß innenliegende Flächen, wie beispielsweise die Ständerboh rung nicht einwandfrei von der Gußmasse bedeckt werden. Ins besondere dringt die Gußmasse nicht zwischen die einzelnen Bleche des Ständerblechpaketes, so daß gesonderte Maßnahmen ergriffen werden müssen um ein Eindringen von Wasser zwischen die Ständerbleche zu verhindern, wenn die Maschine als soge nannter Naßläufer eingesetzt werden soll.Such a machine is known from EP-A-0 357 913. In this machine, the housing body is in the centrifugal casting drive manufactured. With such a procedure can be practically only produce rotationally symmetrical bodies. This has the consequence that radially outward from the housing ing, irregularly shaped parts, such as the Terminal box or the feet of the machine separately on the Ge housing must be attached. Another disadvantage is that internal surfaces, such as the stand drill tion are not properly covered by the casting compound. Ins in particular, the casting compound does not penetrate between the individual Sheets of the stator core, so that separate measures must be taken to prevent water from entering between to prevent the stand plates when the machine as a so-called called wet runner is to be used.
Der Erfindung liegt die Aufgabe zugrunde, eine elektrische Maschine zu schaffen, die wesentlich günstiger gefertigt wer den kann.The invention has for its object an electrical To create machines that are manufactured much cheaper that can.
Die Lösung der gestellten Aufgabe gelingt durch die im Kenn zeichen des Anspruches 1 angegebenen Merkmale. Die Herstel lung des Gehäusekörpers im Spritzgußverfahren ermöglicht von der zylindrischen Form abweichende Ausführungen des Gehäuse körpers. Außerdem ist eine einwandfreie Bedeckung der Fläche der Ständerbohrung gewährleistet. Infolge des beim Spritzgie ßen herrschenden Druckes dringt die Gußmasse auch zwischen die Ständerbleche, so daß diese gegen Korrosion geschützt werden. Da die Gußmasse beim Spritzgießen die Ständerwicklung gasdicht und ohne Gaseinschlüsse in der Spritzmasse um schließt, ergeben sich auch hinsichtlich der elektrischen Isolierung wesentliche Verbesserungen der Maschine. Es wird beispielsweise eine Spannungsfestigkeit von größer 1000 Volt erreicht. Hierzu trägt auch noch bei, daß durch die in der Gußmasse enthaltene Wärme eine Trocknung der Wicklung er folgt. Durch den dichten Einschluß der Ständerwicklung ist auch ein beständiger Schutz der Wicklung gegen Feuchtigkeit und aggressive Medien, wie Amoniak, Öl, Frigen etc. gegeben.The task is solved by the in the Kenn Character of claim 1 specified features. The manufacturer development of the housing body in the injection molding process made possible by Designs of the housing deviating from the cylindrical shape body. In addition, the surface is perfectly covered the stator bore ensures. As a result of the injection molding The prevailing pressure also penetrates the casting compound the stand sheets so that they are protected against corrosion will. Since the molding compound during injection molding the stator winding gas-tight and without gas inclusions in the molding compound closes, also arise with regard to the electrical Isolation essential improvements to the machine. It will for example a dielectric strength of more than 1000 volts reached. This also contributes to the fact that in the Cast material contained heat drying the winding he follows. Due to the tight enclosure of the stator winding also a permanent protection of the winding against moisture and aggressive media such as ammonia, oil, frigen etc.
Vorteilhaft ist es, einen notwendigen Klemmenkasten und/oder Aufstellfüße beim Herstellen des Gehäusekörpers gleich mit anzuformen. Damit entfallen gesonderte Montagevorgänge.It is advantageous to have a necessary terminal box and / or Set-up feet when manufacturing the housing body to form. This eliminates separate assembly processes.
Eine weitere Montagevereinfachung ergibt sich dadurch, daß mit der Ständerwicklung verbundene Anschlußelemente in Wan dungen des Klemmenkastens eingespritzt sind. Damit werden diese Anschlußklemmen beim Spritzen des Gehäusekörpers an schlußfertig im Klemmenkasten festgelegt. Sind die Anschluße lemente als Stecklaschen ausgebildet, so braucht für das elektrische Anschließen der Maschine lediglich ein Stecker auf die Stecklaschen aufgesteckt zu werden.A further simplification of the assembly results from the fact that connection elements connected to the stator winding in Wan the terminal box are injected. With that these terminals when spraying the housing body ready to use in the terminal box. Are the connections elements designed as plug-in tabs, so for that electrical connection of the machine only a plug to be put on the tabs.
Auf der Antriebsseite der Maschine kann für den Anschluß ei nes an die Maschine anzubauenden Teiles ein Zentrierring an der Stirnseite des Gehäusekörpers eingespritzt werden.On the drive side of the machine you can ei a centering ring on the part to be attached to the machine the face of the housing body are injected.
Ferner können für an die Maschine anzubauende Teile, z. B. eine anzutreibende Pumpe oder ein Lagerschild, Gewindeboh rungen in dem Zentrierring vorgesehen werden. Es besteht auch die Möglichkeit bei einem Verzicht auf den Zentrierring Ge windehülsen in den Gehäusekörper einzuspritzen, die sowohl zum Befestigen als auch zum Zentrieren eines mit der Maschine zu verbindenden Teiles dienen.Furthermore, for parts to be attached to the machine, e.g. B. a pump to be driven or a bearing plate, threaded hole stations are provided in the centering ring. It also exists the possibility of dispensing with the centering ring Ge inject wind sleeves into the housing body, both for fastening as well as for centering one with the machine serve to be connected part.
Anhand eines in der Zeichnung dargestellten Ausführungsbei spieles wird die Erfindung nachfolgend noch näher erläutert.Based on an exemplary embodiment shown in the drawing game, the invention is explained in more detail below.
Es zeigt:It shows:

Mit 1 ist der Gehäusekörper einer elektrischen Maschine be zeichnet. Dieser Gehäusekörper 1 ist im Spritzgußverfahren hergestellt und umschließt sowohl das Ständerblechpaket 2 als auch die in dessen Nuten eingelegte Ständerwicklung 3 der Ma schine. Am Außenumfang des Gehäusekörpers 1 sind ein Klemmen kasten 4 und Aufstellfüße 5 einteilig angespritzt.With 1 the housing body of an electrical machine is characterized. This housing body 1 is made by injection molding and encloses both the stator core 2 and the stator winding 3 inserted into the slots of the machine. On the outer circumference of the housing body 1 , a terminal box 4 and feet 5 are molded in one piece.
