Abstract
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.
