Description
Die Erfindung betrifft eine elektrische Maschine zur Umwandlung von elektrischer Energie in mechanische Arbeit, die stromdurchflossene Leiter, ein Motorgehäuse, und einen am Motorgehäuse angeordneten Motorflansch umfasst.The invention relates to an electrical machine for converting electrical energy into mechanical work, which comprises current-carrying conductors, a motor housing, and a motor flange arranged on the motor housing.
Elektrische Maschinen der gartungsgemäßen Art werden im allgemeinen als Elektromotor bezeichnet und finden in einer Vielzahl von Maschinen Anwendung.Electrical machines of this type are generally referred to as electric motors and are used in a wide variety of machines.
Bei der Umwandlung der elektrischen Energie in mechanische Arbeit entsteht Wärme, die abgeführt werden muss. Meist wird dies durch am Gehäuse des Elektromotors angebrachte Kühlrippen oder durch spezielle Kühlmittel wie Wasser erreicht.When electrical energy is converted into mechanical work, heat is generated that must be dissipated. This is usually achieved by cooling fins attached to the housing of the electric motor or by special coolants such as water.
Die entstehende Wärme wirkt sich nachteilig auf die Leistung des Elektromotors aus, da sich die elektrischen Widerstände in der elektrischen Maschine erhöhen und diese nicht mehr im Leistungsoptimum betrieben werden kann. Bestimmte Einzelteile des Elektromotors erlauben nur begrenzte Betriebstemperaturen.The heat generated has a detrimental effect on the performance of the electric motor, as the electrical resistance in the electric machine increases and it can no longer be operated at optimum performance. Certain individual parts of the electric motor only allow limited operating temperatures.
Die Erfindung stellt sich daher die Aufgabe, eine elektrische Maschine derart weiterzubilden, dass die auftretende Wärmeenergie besser abgeführt wird, um die Leistungsdichte der Maschine zu erhöhen.The invention therefore has the object of developing an electrical machine in such a way that the heat energy that occurs is better dissipated in order to increase the power density of the machine.
Die Lösung der Aufgabe ist in Verbindung mit dem Oberbegriff des Anspruchs 1 gekennzeichnet durch einen mit dem Motorflansch in Verbindung stehenden Maschinenflansch, wobei der Maschinen-The solution to the problem is characterized in conjunction with the preamble of claim 1 by a machine flange connected to the motor flange, wherein the machine
K G 046 DE Jul-01K G 046 EN Jul-01
flansch mit einem oder mehreren Mitteln zum Kühlen versehen ist, um zusätzlich Wärme abzuführen.flange is provided with one or more cooling means to dissipate additional heat.
Hierbei ist der Flansch in seinen Materialeigenschaften derart ausgelegt, dass er ausreichend Wärme aufnehmen und folglich vom Elektromotor abführen kann. Bei dieser Anordnung kann bis zu 20% mehr Wärmeenergie aus dem System abgeführt werden und somit wird die Leistungsdichte des Elektromotors erhöht.The material properties of the flange are designed in such a way that it can absorb sufficient heat and thus dissipate it from the electric motor. With this arrangement, up to 20% more heat energy can be dissipated from the system, thus increasing the power density of the electric motor.
Um die Wärmeabfuhr zusätzlich zu verbessern ist weiterbildungsgemäß vorgesehen, dass der Motorflansch mit seinen Auflageflächen mit dem Maschinenflansch verbunden ist, die am Maschinenflansch angeordneten Mittel zum Kühlen können beispielsweise Wärmetauscher oder zusätzliche Kühlrippen sein. Es ist aber auch denkbar, einen Flüssigkeitskreislauf, wie beispielsweise einen Kühlmittelkreislauf mit Wasser, als Mittel zum Kühlen einzusetzen, der die Wärme über einen im Kreislauf angeordneten Wärmetauscher aus dem System abfuhrt.In order to further improve heat dissipation, the development provides that the motor flange is connected to the machine flange with its support surfaces; the cooling means arranged on the machine flange can be, for example, heat exchangers or additional cooling fins. However, it is also conceivable to use a liquid circuit, such as a coolant circuit with water, as a means of cooling, which dissipates the heat from the system via a heat exchanger arranged in the circuit.
Die vorgeschlagene elektrische Maschine eignet sich vor allem zum Betreiben von Teilen einer Spritzgießmaschine zur Verarbeitung von vorzugsweise thermoplastischen Kunststoffen.The proposed electrical machine is particularly suitable for operating parts of an injection molding machine for processing preferably thermoplastics.
In der Zeichnung ist schematisch eine elektrische Maschine 1 dargestellt, die stromdurchflossene Leiter 2 aufweist. Am Motorgehäuse 3 ist ein Motorflansch 4 angeordnet. Dieser weist eine gute wärmeleitfahige Verbindung zum Maschinenflansch 5 auf, damit die Wärme abgeführt werden kann. Der Maschinenflansch 5 ist mit einem oder mehreren Mitteln zum Kühlen 6 versehen, um die Wärmeabfuhr zu gewährleisten.The drawing shows a schematic representation of an electrical machine 1 which has conductors 2 through which current flows. A motor flange 4 is arranged on the motor housing 3. This has a good thermally conductive connection to the machine flange 5 so that the heat can be dissipated. The machine flange 5 is provided with one or more cooling means 6 to ensure heat dissipation.
