Die Erfindung betrifft eine elektrische Maschine, bei der eine wendeiförmige, mit mindestens zwei Anschlußenden versehene Rohrschlange in der Gehäusewand des Maschinengehäuses angeordnet ist.The invention relates to an electrical machine in which a helical pipe coil provided with at least two connection ends is arranged in the housing wall of the machine housing.

Eine solche Maschine ist durch die US-A-I 830 457 bekannt. Bei dieser Maschine ist eine metallische Rohrschlange in das aus Kunststoff bestehende Gehäuse der Maschine eingegossen. Zur Kühlung des Motors wird während des Motorbetriebes ein Kühlmittel durch die Rohrschlange geschickt. Da der Kunststoff des Maschinengehäuses schlecht wärmeleitend ist, kann die im Ständer der Maschine erzeugte Verlustwärme nicht optimal zu der vom Kühlmittel durchflossenen Rohrschlange übertragen werden.Such a machine is known from US-A-I 830 457. In this machine, a metal coil is cast into the machine's plastic housing. To cool the motor, a coolant is sent through the coil while the motor is running. Since the plastic of the machine housing is a poor conductor of heat, the waste heat generated in the machine's stator cannot be optimally transferred to the coil through which the coolant flows.

Der Erfindung liegt die Aufgabe zugrunde, eine elektrische Maschine derart auszubilden, daß die Wärmeübertragung zwischen dem Ständer der Maschine und der Kühlrohrschlange wesentlich verbessert ist.The invention is based on the object of designing an electrical machine in such a way that the heat transfer between the stator of the machine and the cooling coil is significantly improved.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß das Maschinengehäuse aus Grauguß und die Rohrschlange aus einem Stahlrohr besteht. Da Grauguß eine sehr hohe Wärmeleitfähigkeit besitzt, ist eine sehr gute Wärmeableitung vom Ständer der Maschine zu der im Maschinengehäuse eingebetteten Rohrschlange gegeben.The solution to the problem is achieved according to the invention by the machine housing being made of gray cast iron and the pipe coil being made of a steel pipe. Since gray cast iron has a very high thermal conductivity, very good heat dissipation is achieved from the machine stand to the pipe coil embedded in the machine housing.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung nachfolgend näher beschrieben. 35The invention is described in more detail below using an embodiment shown in the drawing. 35

Mit 1 ist das Gehäuse einer elektrischen Maschine bezeichnet. In ein solches Gehäuse 1 wird in bekannter Weise das Ständerblechpaket der Maschine eingebracht. Zur Kühlung der elektrischen Maschine ist in der Gehäusewand 2 des Gehäuses 1 eine wendeiförmige Rohrschlange 3 angeordnet, die mit zwei Anschlußenden A und 5 versehen ist. Während des Betriebes der elektrischen Maschine wird der Rohrschlange 3 z.B. an dem einen Anschlußende 4 eine Kühlflüssigkeit zugeführt, die am anderen Anschlußende 5 wieder aus der Rohrschlange 3 austritt.The housing of an electrical machine is designated with 1. The stator core of the machine is inserted into such a housing 1 in a known manner. To cool the electrical machine, a helical pipe coil 3 is arranged in the housing wall 2 of the housing 1, which is provided with two connection ends A and 5. During operation of the electrical machine, a cooling liquid is fed to the pipe coil 3, e.g. at one connection end 4, which exits again from the pipe coil 3 at the other connection end 5.

Das dargestellte Gehäuse 1 besteht aus Grauguß so daß eine gute Wärmeleitverbindung zwischen dem in das Gehäuse eingebauten Ständerblechpaket und der Rohrschlange 3 besteht. Damit ist eine intensive Kühlung der elektrischen Maschine möglich.The housing 1 shown is made of gray cast iron so that there is a good thermal conduction connection between the stator core built into the housing and the pipe coil 3. This enables intensive cooling of the electrical machine.
