Abstract

The electric machine (1) contains current carrying conductors (2), a motor casing (3) and a motor flange (4) on the casing. The motor flange is coupled to a machine flange (5) with one or more cooling members (6).Preferably the machine flange is capable to absorb heat. The cooling member is typically a heat exchanger, but cooling ribs may also be used. A coolant circuit may be used and may contain the heat exchanger. An Independent claim is included for a thermoplastics processing injection molding machine driven by electric motor(s).

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 in mechanical work, the current-carrying Conductor, a motor housing, and one arranged on the motor housing Motor flange includes.

Elektrische Maschinen der gattungsgemäßen Art werden im allgemeinen als Elektromotor bezeichnet und finden in einer Vielzahl von Maschinen Anwendung. Electrical machines of the generic type are generally referred to as an electric motor and found in a variety of machines Application.

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 converting electrical energy into mechanical work there is heat that must be dissipated. This is usually done by on Housing of the electric motor attached cooling fins or by special Coolant like water reached.

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 adversely affects the performance of the Electric motor because the electrical resistances in the electrical Increase the machine and no longer operate it at optimum performance can be. Certain 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 as its object an electrical To further develop the machine in such a way that the thermal energy that occurs is better dissipated 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 Maschinenflansch mit einem oder mehreren Mitteln zum Kühlen versehen ist, um zusätzlich Wärme abzuführen. The solution to the problem is in connection with the Preamble of claim 1 characterized by one with the motor flange related machine flange, the Machine flange is provided with one or more cooling means 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 such that that it absorb sufficient heat and consequently from the electric motor can dissipate. With this arrangement up to 20% more can be done Thermal energy can be dissipated from the system and thus the Power density of the electric motor increased.

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 abführt. In order to further improve the heat dissipation, it is in accordance with further training provided that the motor flange with its contact surfaces with the Machine flange is connected to the machine flange arranged means for cooling can, for example, heat exchangers or additional cooling fins. But it is also conceivable to have one Liquid circuit, such as a coolant circuit with water, as Means for cooling that use the heat via a circuit arranged heat exchanger leads away from the system.

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 wärmeleitfähige 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. Bezugszeichenliste 1 elektrische Maschine
