Description

Beschreibung description
Elektrische Maschine mit einem Stator sowie deren Verfahren zur Herstellung eines derartigen Stators Electric machine with a stator and its method for producing such a stator
Die Erfindung betrifft eine elektrische Maschine mit einem Stator, in dessen Nuten ein Wicklungssystem angeordnet ist, ein Verfahren zur Herstellung einer derartigen Stators einer elektrischen Maschine und die Verwendung derartiger elektrischer Maschinen. The invention relates to an electrical machine with a stator, in whose grooves a winding system is arranged, a method for producing such a stator of an electrical machine and the use of such electrical machines.
Das Wicklungssystem elektrischer Maschinen im Stator und/oder Rotor ist elektromagnetischen Schwingungsanregungen ausgesetzt, die aufgrund der ortsfesten Fixierung des Wicklungs¬ systems innerhalb der Nut durch dementsprechende Verguss¬ massen und Tränkharze in den Aktivteilen der elektrischen Maschine, also Stator und/oder Rotor an diese Aktivteile und damit letztlich an die Umgebung abgegeben werden. The winding system of electrical machines in the stator and / or rotor is exposed to electromagnetic vibration excitations, due to the stationary fixation of the winding ¬ system within the groove by appropriate potting ¬ masses and impregnating resins in the active parts of the electric machine, so the stator and / or rotor to these active parts and ultimately delivered to the environment.
Durch Betrieb von z.B. einer dynamoelektrischen Maschine an einem Umrichter treten derartige Schwingungsanregungen verstärkt auf. Dem wird dadurch versucht zu begegnen, dass die diese elektrischen Maschinen beispielsweise Schalldämmmatten am Gehäuse aufweisen, um dementsprechende Schallemissionen zu reduzieren. Nachteilig dabei ist u.a., dass sich dadurch die Abmessungen der dynamoelektrischen Maschine vergrößern und/oder Kühlluftströme innerhalb der dynamoelektrischen Maschine beeinträchtigt werden. By operation of e.g. a dynamoelectric machine on a converter occur such vibration excitations increasingly. This is attempted to counteract that these electrical machines, for example, have sound insulation mats on the housing in order to reduce corresponding sound emissions. The disadvantage here is, inter alia, that thereby enlarge the dimensions of the dynamoelectric machine and / or cooling air flows are impaired within the dynamoelectric machine.
Ausgehend davon liegt der Erfindung die Aufgabe zugrunde, ei¬ ne elektrische Maschine, insbesondere dynamoelektrische Ma¬ schine zu schaffen, die vor allem Schallemissionen auch bei Umrichterbetrieb der dynamoelektrischen Maschine reduziert. On this basis, the invention has the object, in particular to provide dynamoelectric Ma ¬ machine that reduces even in converter of the dynamoelectric machine mainly acoustic emissions ei ¬ ne electric machine.
Die Lösung der gestellten Aufgabe gelingt durch eine elektrische Maschine mit einem Stator, mit magnetfeldführendem Material, in dem sich im Wesentlichen axial verlaufende Nuten befinden, wobei in den Nuten ein Wicklungssystem vorgesehen ist, das von Tränkharz umgeben und/oder durchsetzt ist, wobei das Tränkharz energieabsorbierende Partikel aufweist. The solution of the problem is achieved by an electric machine with a stator, with magnetic field leading material in which are substantially axially extending grooves, wherein provided in the grooves, a winding system is that surrounded by impregnating resin and / or interspersed, wherein the impregnating resin has energy-absorbing particles.
Die Lösung der Aufgabe gelingt ebenso durch ein Verfahren zur Herstellung einer elektrischen Maschine mit einem Stator und/oder Rotors durch folgende Schritte: The object is also achieved by a method for producing an electric machine with a stator and / or rotor by the following steps:
- Bereitstellen eines magnetfeldführenden Körpers mit Nuten, Providing a magnetic field guiding body with grooves,
- Einsetzen eines Wicklungssystems, - insertion of a winding system,
- Tränken/Vergießen des Wicklungssystems mittels eines mit Partikeln versetzen Tränkharzes oder Vergussmaterials.  - Impregnating / casting of the winding system by means of a particles impregnated resin or potting material.
Erfindungsgemäß wird nunmehr die Aufgabe der Reduktion der Schallemissionen dadurch gelöst, in dem die schwingungsfähigen Wicklungssysteme, d.h., insbesondere die einzelnen Drähte bzw. elektrischen Leiter in ein Tränkharz bzw. in eine According to the invention, the object of reducing the noise emissions is now achieved in that the oscillatory winding systems, that is, in particular the individual wires or electrical conductors in a impregnating resin or in a
Vergussmasse eingebettet sind, die energieabsorbierte Parti¬ kel aufweist. Damit wird vermieden, dass sich derartige Potting compound are embedded, which has energy-absorbed Parti ¬ cle. This avoids that such
Schwingungen auf das benachbarte magnetfeldführende Material, insbesondere die Blechpakete von Stator und/oder Rotor der dynamoelektrischen Maschine fortpflanzen und dementsprechend Schall an die Umgebung emittieren. Vibrations propagate to the adjacent magnetic field leading material, in particular the laminated cores of the stator and / or rotor of the dynamoelectric machine and accordingly emit sound to the environment.
In einer Ausgestaltung sind die Partikel, insbesondere faden¬ förmig ausgeführt, um dabei dann ihre Ausrichtung innerhalb der Nut zwischen den einzelnen Leitern und/oder den Leitern und den umgebenden magnetfeldführenden Material vornehmen zu können. Dabei wird eine Ausrichtung bevorzugt, die besonders energieabsorbierend ist, d.h. bei fadenförmigen Partikeln sind diese beispielsweise entweder mikroschraubenartartig oder knäulartig ausgeführt. Diese Anordnungen der fadenförmigen Partikel verstärken den energieabsorbierenden Effekt. In one embodiment, the particles, in particular thread-shaped ¬ designed to then make their alignment within the groove between the individual conductors and / or the conductors and the surrounding magnetic field leading material. In this case, an orientation is preferred which is particularly energy-absorbing, ie in thread-like particles, these are carried out, for example, either micro-screw type or like a coccyx. These filamentary particle arrangements enhance the energy absorbing effect.
Die Partikel, insbesondere auch Nanopartikel , also Partikel die in ihrer Ausdehnung kleiner 100 Nanometer sind, werden vorteilhafterweise homogen innerhalb des Tränkharzes angeord¬ net . Ansonsten weisen diese fadenförmigen Partikel eine Längenausdehnung von bis zu einigen Millimeter auf, bei dementspre- chenden Durchmessern von einigen Mikrometern. Insbesondere bei kürzeren Partikeln kann sich der Durchmesser bis auf ei- nige Nanometer verringern. The particles, especially nanoparticles, that is particles which are smaller than 100 nanometers in its extension advantageously be homogeneous within the impregnating resin angeord ¬ net. Otherwise, these thread-like particles have a length extension of up to a few millimeters, with corresponding diameters of a few micrometers. Especially with shorter particles, the diameter can be reduced to a few nanometers.
Sollten jedoch an besonders schwingungsfähigen Bereichen der Wicklung verstärkt Schwingungsbäuche auftreten, die zu However, should occur at particularly vibratory areas of the winding amplified antinodes, the
Schallemissionen führen, können dort beim Herstellungsprozess auch verstärkt diese Partikel im Tränkharz vorgesehen werden. In the manufacturing process, these particles can also be reinforced in the impregnating resin.
Die Erfindung sowie vorteilhafte Ausgestaltungen der Erfindung werden anhand der folgenden Zeichnungen näher erläutert. Darin zeigen: The invention and advantageous embodiments of the invention will be explained in more detail with reference to the following drawings. Show:
FIG 1 einen prinzipiellen Längsschnitt einer elektrischen Maschine, 1 shows a principal longitudinal section of an electrical machine,

FIG 1 zeigt in einer prinzipiellen Darstellung eine elektrische Maschine 1 mit einem Stator 2, der in dieser Ausführungsform ein Blechpaket 12 aufweist, wobei das magnetfeld- führende Teil auch als einstückiges Material z.B. als 1 shows in a schematic representation an electric machine 1 with a stator 2, which in this embodiment has a laminated core 12, wherein the magnetic field-carrying part as a one-piece material, e.g. when
Kompositwerkstoff vorgesehen sein kann. In diesem magnetfeld¬ führenden Material 12 sind im Wesentlichen axial verlaufende Nuten 4 angeordnet, in denen das Wicklungssystem 3 untergebracht ist, das an den Stirnseiten des Stators 2 Wickelköpfe 8 ausbildet. Über dementsprechende elektromagnetische Wech¬ selwirkungen mit einem Rotor 9 dreht sich dieser Rotor 9 um eine Achse 10 und kann dabei über eine Welle 11 eine Arbeits¬ maschine antreiben. FIG 2 zeigt in einem Ausschnitt des magnetfeldführenden Mate¬ rials also z.B. des Blechpaketes 12 eine Nut 4 in das eine Spule des Wicklungssystems 3 eingesetzt ist, wobei die Spule aus einer Vielzahl von einzelnen Drähten 5 besteht. Die Dräh- te 5 weisen Abstände zueinander auf, in die das Tränkharz durch dementsprechend geeignete Methoden eingefüllt wird, um danach ausgehärtet einen festen Verbund mit den magnetfeld¬ führenden Blechpaket 12 zu bilden. Zwischen den Drähten 5 und/oder auch zwischen den Drähten 5 und der Nutwand 4 sind nunmehr Partikel 7 innerhalb des Tränkharzes angeordnet, die energieabsorbierend ausgeführt sind. Dabei liegen die ur¬ sprünglich, insbesondere fadenförmig, vorliegenden Partikel 7 im Tränkharz nunmehr aufgrund eines physikalischen oder che- mischen Prozess während des Tränkungsprozesses oder danach in schwingungsabsorbierender Form vor, also als knäulartige, schraubenförmige oder kugelförmige Gebilde. Composite material can be provided. In this magnetic field ¬ leading material 12 substantially axially extending grooves 4 are arranged, in which the winding system 3 is housed, which forms on the front sides of the stator 2 winding heads 8. About corresponding electromagnetic Wech ¬ selwirkungen with a rotor 9, this rotor 9 rotates about an axis 10 and can thereby drive a working ¬ machine via a shaft 11. FIG 2 thus shows in a section of the magnetic field leading mate rials ¬ example of the laminated core 12, a groove in which a coil of the winding system is used 3 4, wherein the coil consists of a plurality of individual wires. 5 The wires te 5 have distances to each other, in which the impregnating resin is filled by appropriately suitable methods, then cured to form a solid bond with the magnetic field ¬ leading laminated core 12. Between the wires 5 and / or between the wires 5 and the groove wall 4 now particles 7 are arranged within the impregnating resin, which are designed to absorb energy. The ur ¬ nally, in particular thread-like, present in the impregnating resin particles 7 are now due to a physical or chemical blend process during or after Tränkungsprozesses in vibration dampening form, so as knäulartige helical or spherical structures.
Die dabei eingesetzten Prozesse können beispielsweise eine besondere Wärmebehandlung und/oder ein katalytisch in Gang gesetzter Vorgang im Tränkharz 6 sein, der zu einer energieabsorbierenden Formgebung der Partikel 7 führt. The processes used in this case can be, for example, a special heat treatment and / or a catalytically initiated process in the impregnating resin 6, which leads to an energy-absorbing shaping of the particles 7.
Diese Partikel 7 sind dann spiralförmig, kugelfömig, zick- zack-förmig oder knäulartig ausgebildet, wie sie prinzipiell in FIG 3 dargestellt sind. These particles 7 are then formed in a spiral, spherical, zigzag-shaped or knob-like manner, as shown in principle in FIG.
