Description

Die Erfindung betrifft eine elektrische Antriebsvorrichtung nach der im Oberbegriff von Anspruch 1 näher definierten Art. Des weiteren betrifft die Erfindung eine Verwendung einer elektrischen Antriebsvorrichtung gemäß den Ansprüchen 5 und 6.The invention relates to an electrical Drive device according to the closer defined in the preamble of claim 1 Art. Furthermore, the invention relates to a use of an electric drive device according to claims 5 and 6th

Eine gattungsgemäße elektrische Antriebsvorrichtung ist aus der WO 01/11755 A1 bekannt. Um größere Drehzahlen zu erreichen, sind hierbei die Permanentmagnete des Rotors in einen faser- oder gewebearmierten Kunststoff eingebettet und auf diese Weise formschlüssig mit demselben verbunden.A generic electric drive device is known from WO 01/11755 A1. To reach higher speeds, Here are the permanent magnets of the rotor in a fiber or fabric-armored Embedded plastic and in this way with a positive fit with connected to it.

Beispielsweise Kolbenpumpen oder Klauenverdichter, die mit derartigen Antriebsvorrichtungen angetrieben werden können, sind im Betrieb sehr hohen Drehmomentschwankungen ausgesetzt, die dazu führen, dass sich der Lastwinkel der Antriebsvorrichtung in entsprechend weiten Grenzen ändert. Dies wiederum führt zu starken Torsionsschwingungen, mit der Folge dass beim Antrieb solcher Maschinen eine Regelung der elektrischen Antriebsvorrichtung annähernd unmöglich ist. Des weiteren werden, insbesondere wenn es sich bei der elektrischen Antriebsvorrichtung um einen permanenterregten Synchronmotor handelt, zusätzliche Verluste durch Wirbelströme verursacht.For example, piston pumps or Claw compactors driven by such drive devices can be are exposed during operation very high torque fluctuations, which to lead, that the load angle of the drive device in accordance with wide limits changes. This in turn leads too strong torsional vibrations, with the consequence that the drive Such a regulation of the electric drive device nearly impossible is. Furthermore, especially when it comes to the electrical Drive device is a permanent-magnet synchronous motor, additional Losses due to eddy currents caused.

Außerdem muss bei derartigen Antriebsvorrichtungen eine separate, als Schwungmasse dienende Schwungscheibe in einem zusätzlichen Gehäuse separat gelagert werden. Dadurch entstehen meist sehr kompliziert aufgebaute Antriebsvorrichtungen, die verhältnismäßig teuer sind.In addition, with such Drive devices a separate, serving as flywheel flywheel in an additional casing be stored separately. This usually causes very complicated constructed drive devices that are relatively expensive.

Es ist daher Aufgabe der vorliegenden Erfindung, eine elektrische Antriebsvorrichtung, insbesondere zum Antrieb eines Klauenverdichters oder einer Kolbenpumpe, zu schaffen, welche in der Lage ist, derartige Maschinen, die während ihres Betriebs sehr hohen Drehmomentschwankungen ausgesetzt sind, so anzutreiben, dass eine Regelung der Antriebsvorrichtung möglich ist.It is therefore the task of the present Invention, an electric drive device, in particular for Drive a claw compressor or a piston pump to provide which is capable of such machines during their Operating are subjected to very high torque fluctuations, so driving that a regulation of the drive device is possible.

Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention this object is achieved by the solved in claim 1 features.

Durch die erfindungsgemäße einteilige Ausführung der Schwungmasse mit dem Rotor können die beschriebenen Torsionsschwingungen so gedämpft werden, dass eine Regelung der Antriebsvorrichtung problemlos möglich ist. Durch die erfindungsgemäße Lösung ergibt sich vorteilhafterweise nur ein geringer fertigungstechnischer Mehraufwand, der mit nahezu unveränderten Außenabmessungen der gesamten Antriebsvorrichtung verbunden ist.By the invention one-piece execution the flywheel with the rotor can the described torsional vibrations are damped so that a scheme the drive device is easily possible. By the solution according to the invention results advantageously only a small manufacturing overhead, the with almost unchanged Outside dimensions of the entire drive device is connected.

Vorteilhafte Verwendungen der erfindungsgemäßen elektrischen Antriebsvorrichtung sind in den Ansprüchen 5 und 6 angegeben.Advantageous uses of the electrical according to the invention Drive device are specified in claims 5 and 6.

Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus den nachfolgend anhand der Zeichnung prinzipmäßig dargestellten Ausführungsbeispielen.Further advantageous embodiments and further developments of the invention will become apparent from the dependent claims and from the below principle with reference to the drawing Embodiments.

1 eine Explosionsdarstellung einer ersten Ausführungsform der erfindungsgemäßen elektrischen Antriebsvorrichtung; 1 an exploded view of a first embodiment of the electric drive device according to the invention;

2 eine Schnittdarstellung der elektrischen Antriebsvorrichtung aus 1; 2 a sectional view of the electric drive device 1 ;

3 eine Explosionsdarstellung einer zweiten Ausführungsform der erfindungsgemäßen elektrischen Antriebsvorrichtung; und 3 an exploded view of a second embodiment of the electric drive device according to the invention; and

4 eine Schnittdarstellung der elektrischen Antriebsvorrichtung aus 3. 4 a sectional view of the electric drive device 3 ,

Die 1 und 2 zeigen eine elektrische Antriebsvorrichtung 1, im vorliegenden Fall eine permanenterregte Synchronmaschine. Die elektrische Antriebsvorrichtung 1 weist einen Rotor 2 und einen in dieser Ausführungsform aus zwei Wicklungen 3 und 4 bestehenden Stator 5 auf. Der Rotor 2 weist seinerseits eine Welle 6 auf, die über eine erste Lagereinrichtung 7 in einem vorderen Lagerschild 8 und über eine zweite Lagereinrichtung 9 in einem hinteren Lagerschild 10 gelagert ist. Die beiden Lagerschilde 8 und 10 schließen sich unmittelbar an die beiden Wicklungen 3 und 4 des Stators 5 an und sind ihrerseits mittels jeweiliger Deckel 11 und 12 verschossen. Die beiden Deckel 11 und 12 können mit einem Gehäusering 13 verschraubt werden und bilden somit zusammen mit dem Gehäusering 13 das Gehäuse der elektrischen Antriebsvorrichtung 1.The 1 and 2 show an electric drive device 1, in the present case, a permanent magnet synchronous machine. The electric drive device 1 has a rotor 2 and one in this embodiment of two windings 3 and 4 existing stator 5 on. The rotor 2 in turn has a wave 6 on that over a first storage facility 7 in a front bearing plate 8th and a second storage facility 9 in a rear end shield 10 is stored. The two end shields 8th and 10 close directly to the two windings 3 and 4 of the stator 5 and are in turn by means of respective cover 11 and 12 Missed. The two lids 11 and 12 can with a housing ring 13 be bolted and thus form together with the housing ring 13 the housing of the electric drive device 1 ,

Um Torsionsschwingungen ausgleichen zu können, die beim Antrieb eines nicht dargestellten Klauenverdichters oder einer ebenfalls nicht dargestellten Kolbenpumpe mittels der elektrischen Antriebsvorrichtung 1 an der Welle 6 auftreten können, ist eine Schwungmasse 14 einteilig mit dem Rotor 2 ausgeführt. Diese einteilige Ausführung aus Rotor 2 und Schwungmasse 14 ist einfach zu fertigen und wirkt darüber hinaus schwingungsdämpfend auf den Rotor 2.In order to compensate for torsional vibrations when driving a claw compressor, not shown, or a piston pump, also not shown by means of the electric drive device 1 on the shaft 6 can occur is a flywheel 14 in one piece with the rotor 2 executed. This one-piece version made of rotor 2 and flywheel 14 is easy to manufacture and also has a vibration-damping effect on the rotor 2 ,

Im vorliegenden Fall weist der Rotor 2 mehrere Magnetsegmente 15 auf, die sowohl mit einem als Nabe dienenden Innenring 16 als auch mit einem eine Bandage bildenden Außenring 17 des Rotors 2 verbunden sind. Die Verbindung der Magnetsegmente 15 mit dem Innenring 16 und dem Außenring 17 des Rotors 2, die vorzugsweise aus Stahl bestehen, wird dabei durch Verpressen mit einem Harz, vorzugsweise einem faserbewehrten Duroplast, erreicht.In the present case, the rotor 2 several magnet segments 15 on, both with a hub serving as inner ring 16 as well as with a bandage forming outer ring 17 of the rotor 2 are connected. The connection of the magnet segments 15 with the inner ring 16 and the outer ring 17 of the rotor 2 , which are preferably made of steel, is achieved by compression with a resin, preferably a fiber-reinforced thermoset.

Bei der elektrischen Antriebsvorrichtung 1 gemäß den 3 und 4 weist der Stator 5 lediglich die Wicklung 3 auf, wohingegen die Wicklung 4 entfällt. Es handelt sich somit um einen asymmetrischen Motor. Die Schwungmasse 14, die auch hier einteilig mit dem Rotor 2 ausgeführt ist, weist eine geringere Breite als bei der elektrischen Antriebsvorrichtung 1 gemäß den 1 und 2 auf, da sie sich aufgrund der fehlenden Wicklung 4 weiter in radialer Richtung erstrecken kann.In the electric drive device 1 according to the 3 and 4 points the stator 5 only the winding 3 on, whereas the winding 4 eliminated. It is therefore an asymmetrical motor. The flywheel 14 that are also integral with the rotor here 2 is executed, has a smaller width than in the electric drive device 1 according to the 1 and 2 on, as they are due to the lack of winding 4 can continue to extend in the radial direction.
