Aus dem DE-GM 17 97 835 ist es grundsätzlich bekannt, zur Nutenisolation für den Ständer oder Anker eines elektrischen Motors Formkörper zu verwenden. Die Verwendung derartiger Formkörper bringt gegenüber den anderen Isolationsverfahren wie Ausspritzen oder Auskleiden mit einer Folie zwar schon Herstellungsvorteile, jedoch müssen auf der anderen Seite bei den bislang bekannt gewordenen Formkörperisolationen noch erhebliche Nachteile in Kauf genommen werden. Insbesondere mtiß es als nachteilig angesehen werden, daß die Formkörper oft mehrteilig ausgeführt sind und bei der Montage von beiden Seiten axial in die entsprechenden Nuten des Ständerpaketes eingeführt werden müssen. Dadurch ergeben sich aber hinsichtlich der Isolation kritische überlappungsbereiche, die sich dann oft als Isolationsschwachstellen zeigen. Ferner erfordert das Einfügen der Formkörper in die Nuten der Motorenteile eine gewisse Geschicklichkeit und einen entsprechenden Zeitaufwand.From DE-GM 17 97 835 it is known in principle for groove isolation to use molded body for the stator or armature of an electric motor. the The use of shaped bodies of this type brings advantages over the other insulation methods such as injection molding or lining with a film, although manufacturing advantages, however, on the other hand, with the previously known molded body insulation there are still considerable disadvantages to be accepted. In particular, it must be disadvantageous be considered that the moldings are often made in several parts and in the Assembly inserted axially into the corresponding grooves of the stator assembly from both sides Need to become. However, this results in critical overlap areas with regard to the insulation, which then often show up as insulation weak points. It also requires pasting the molded body in the grooves of the engine parts a certain skill and a corresponding expenditure of time.

Der Erfindung liegt die Aufgabe zugrunde, die vorgenannten Nachteile zu vermeiden und ein Verfahren sowie für die Durchführung des Verfahrens geeignete Formkörper zu schaffen, wodurch die Wicklungsisolation mit einfacher Handlichkeit und geringem Zeitaufwand bei der Montage vorgenommen werden kann.The invention is based on the aforementioned disadvantages to avoid and a procedure as well as suitable for the implementation of the procedure To create molded bodies, thereby reducing the winding insulation with ease of handiness and can be done in a short time during assembly.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Formkörper als einteilige Isolations- und Wicklungsstützkörper ausgebildet sind, die vom Innenraum des Ständerpaketes her koaxial in die jeweiligen Pollücken eingeschwenkt werden.According to the invention, this object is achieved in that the shaped bodies are designed as a one-piece insulation and winding support body, which from the interior of the stator assembly can be swiveled coaxially into the respective pole gaps.

Der erfindungsgemäß ausgebildete Formkörper für die Durchführung des Verfahrens ergibt sich aus dem Anspruch 2 und den nachgestellten Unteransprüchen.The shaped body designed according to the invention for carrying out the The method results from claim 2 and the subsequent subclaims.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß je Pollücke ein einteiliger Formkörper verwendet werden kann, der als Isolations- und Wicklungsstützkörper dient und der mit einem einfachen Handgriff sitzfest in die Pollücke des Ständerpaketes einfügbar ist. Die Trennstelle zu dem gegenüberliegenden Isolationskörper erfolgt in einem für die Kriechwege unkritischen Bereich.The advantages that can be achieved with the invention are, in particular, that a one-piece molded body can be used for each pole gap, which acts as an insulation and winding support body and which fits securely in with a simple movement of the hand the pole gap of the stator package can be inserted. The separation point to the opposite The insulation body takes place in an area that is not critical for the creepage distances.
