Ein bekannter Kommutator (US 6 285 106 Bl) besitzt einen auf die Rotorwelle einer Kommutatormaschine drehfest aufsetzbaren, hohlzylindrischen Kommutatorkörper aus Isolierstoff, auf dessen Außenumfang die Kommutatorlamellen mit Spaltabstand voneinander in Umfangsrichtung nebeneinander angeordnet sind. Jede Kommutatorlamelle trägt einstückig eine Anschlussf hne oder -haken zum Anschließen der Spulen einer Rotorwicklung, die in bekannter Weise in Nuten eines drehfest auf der Rotorwelle sitzenden, ferromagnetischen Rotorkörpers eingewickelt ist. Um beim Betrieb der Kommutatormaschine die bei der Kommutierung entstehende, für eine elektromagnetische Störstrahlung ursächliche Funkenbildung zu reduzieren, ist in das von den Anschlusshaken abgekehrte Stirnende des Kommutatorkörpers eine Vertiefung eingearbeitet, in die eine Entstörscheibe, z.B. ein Varistor, so eingelegt ist, dass ihre eine ringförmige Scheibenfläche am Grund der Vertiefung anliegt und die andere, Anschlusselektroden tragende, ringförmige Scheiben läche nach außen weist. Auf die Entstörscheibe ist ein Kontaktring aufgedrückt, der die Anschlusselektroden mit dem Kommutatorlamellen ■ elektrisch leitend verbindet. Der Kontaktring weist einen Basisring aus Isoliermaterial mit einer Vielzahl von jeweils miteinander verbundenen ersten und zweiten Kontakten auf. Die Anzahl der: ersten Kontakte und die Anzahl der zweiten Kontakte entspricht jeweils der Zahl der Kommutatorlamellen bzw. der gleich großen Zahl der Anschlusselektroden an der Entstörscheibe. Jeweils ein erster Kontakt liegt auf einer Anschlusselektrode auf und jeweils ein mit dem ersten Kontakt: in elektrisch leitender Verbindung stehender zweiter Kontakt liegt mit mechanischer Vorspannung an der Unterseite einer der endseitig über die Vertiefung vorstehenden Kommutatorlamellen an. Auf den Kontaktring ist ein Deckel aufgedrückt der die ersten Kontakte an dieA known commutator (US Pat. No. 6,285,106 B1) has a hollow cylindrical commutator body made of insulating material that can be rotatably attached to the rotor shaft of a commutator machine, on the outer circumference of which the commutator lamellae are arranged next to one another in the circumferential direction with a gap distance from one another. Each commutator bar carries in one piece a connecting thread or hook for connecting the coils of a rotor winding, which is wound in a known manner in the slots of a ferromagnetic rotor body seated in a rotationally fixed manner on the rotor shaft. In order to reduce the spark formation that occurs during commutation and that causes electromagnetic interference radiation during operation of the commutator machine, the front end of the Commutator body incorporated a recess, in which a suppressor, such as a varistor, is inserted so that its an annular disc surface rests against the bottom of the recess and the other, connecting electrodes carrying, annular disc surface faces outwards. A contact ring is pressed onto the interference suppression disk, which connects the connection electrodes to the commutator bars ■ in an electrically conductive manner. The contact ring has a base ring made of insulating material with a multiplicity of respectively connected first and second contacts. The number of: first contacts and the number of second contacts each correspond to the number of commutator bars or the same number of connection electrodes on the interference suppression disk. In each case a first contact rests on a connection electrode and in each case one with the first contact: the second contact, which is in an electrically conductive connection, rests with mechanical prestress on the underside of one of the commutator lamellae projecting beyond the recess at the end. A cover is pressed onto the contact ring which connects the first contacts to the

Beschreibung der AusführungsbeispieleDescription of the embodiments
Der in Fig. 1 perspektivisch dargestellte Kommutator .für eine elektrische Maschine, insbesondere für einen Elektromotor für Stellantriebe bei Fahrzeugen, weist einen hohlzylindrischen Kommutatorkörper 11 mit einer äußeren Mantelfläche 111 und einer inneren Mantelfläche 112 auf. Der Kommutatorkorper 11 besteht aus einem elektrisch isolierenden Kunststoff mnd trägt auf seiner inneren Mantelfläche 112 eine Vielzanl von in Umfangsrichtung mit Spaltabstand nebeneinander angeordneten Kommutatorlamellen 12, die sich über die gesamte axiale Länge des Kommutatorkörpers 11 erstrecken. Jede Kommutatorlamelle 12 trägt an einem Lamellenende eine Anschlussfahne oder einen Anschlusshaken 14 (Fig. 2) . In die Anschlusshaken 14, von denen einer in Fig. 3 vergrößert dargestellt ist. werden in bekannter Weise die Spulen einer Anker- oder Rotorwicklung eingehängt und mit: diesen mechanisch und elektrisch verbunden. Die Verbindung erfolgt üblicherweise im sog. Hot-Stacking, einem Heisspres sverfahren, bei dem die Anschlusshaken 14 auf die Kommutatorlamellen 12 aufgedrückt werden, und dabei gleichzeitig im Bereich der Anschlusshaken 14 die Isolation des Ankerwicklungsdrahts abgeschmolzen wird.The commutator shown in perspective in FIG. 1 for an electrical machine, in particular for an electric motor for actuators in vehicles, has a hollow cylindrical commutator body 11 with an outer lateral surface 111 and an inner lateral surface 112. The commutator body 11 consists of an electrically insulating plastic and carries a multitude of on its inner lateral surface 112 Commutator lamellae 12 arranged next to one another in the circumferential direction with a gap spacing, which extend over the entire axial length of the commutator body 11. Each commutator bar 12 carries a terminal lug or a hook 14 (FIG. 2) at one end of the bar. In the hooks 14, one of which is shown enlarged in Fig. 3. the coils of an armature or rotor winding are hung in a known manner and connected to them mechanically and electrically. The connection is usually carried out in what is known as hot stacking, a hot press method in which the connecting hooks 14 are pressed onto the commutator bars 12, and at the same time the insulation of the armature winding wire is melted off in the region of the connecting hooks 14.
Auf das von den Anschlusshaken 14 abgekehrte Stirnende des Kommutato körpers 11 ist ein Deckel 15 aufgesetzt und mit dem Kommutatorkörper 11, z.B. durch Verschraubung oder Verkleben fest verbunden. Der Deckel 15 besteht aus einem Material, der elektromagnetische Strahlungen abschirmt oder absorbiert. Der Deckel 15 besitzt eine zentrale Durchtrittsöffnung 16 für die Rotorwelle 17 (Fig. 5) und dient zur drehfesten und axial unverschieblichen Abstützung des Kommutators auf der Rotorwelle 17. Der Deckel 15 kann auch einstückig mit dem Kommutatorrkörper 11 ausgeführt werden, indem derOn the end of the commutator body 11 facing away from the connecting hook 14, a cover 15 is placed and connected to the commutator body 11, e.g. firmly connected by screwing or gluing. The cover 15 is made of a material that shields or absorbs electromagnetic radiation. The cover 15 has a central passage opening 16 for the rotor shaft 17 (FIG. 5) and serves for the rotationally fixed and axially immovable support of the commutator on the rotor shaft 17. The cover 15 can also be made in one piece with the commutator body 11 by the
Kommutatorkörper 11 becherförmig ausgebildet wird, so dass der Deckel 15 von dem Becherboden gebildet ist.Commutator body 11 is cup-shaped, so that the lid 15 is formed by the cup bottom.
Wie aus der Schnittdarstellung in Fig. 5 zu erkennen ist, in der noch die geschnittene Rotorwelle 17 eingezeichnet ist, ist im Innern des Kommutatorkörpers 11 ein Bürstenhalter 18 mit - zwei diametral am Kommutatorkörper 11 auf den Kommutatorlamellen 12 aufliegenden Kommutatorbürsten 19 angeordnet. Der Bürstenhalter 18 weist einen räumlich feststehenden Tragring 20 auf, an dem zwei Bürstenköcher 21 diametral angeordnet sind. Jeder Bürstenköcher 21 nimmt eine Kommutatorbürste 19 axial vers chieblich auf. Jede Kommutatorbürste 19 wird mittels einer nicht dargestellten Bürstenandruckfeder radial auf die Kommutatorlamellen 12 gedrückt und steht mit einer elektrischen Anschlusslitze 22 in elektrisch leitender Verbindung.As can be seen from the sectional view in FIG. 5, in which the cut rotor shaft 17 is also shown, inside the commutator body 11 there is a brush holder 18 with two diametrically on the commutator body 11 on the Commutator bars 12 arranged commutator brushes 19. The brush holder 18 has a spatially fixed support ring 20 on which two brush holders 21 are arranged diametrically. Each brush holder 21 accommodates a commutator brush 19 axially displaceable. Each commutator brush 19 is pressed radially onto the commutator bars 12 by means of a brush pressure spring (not shown) and is in electrically conductive connection with an electrical connecting wire 22.
Beim Betrieb eines mit einem solchen Kommutator ausgestatteten elektrischen Motors, z. B. eines Gleichstrommotors, entstehen bei jeder Kommutierung Funken, da beim Kommutieren die Spulen der Anker- oder Rotorwicklung für eine sehr kurze Zeitspanne von den Kommutatorbürsten 19 kurzgeschlossen werden und dann deren Kurzschluss wieder aufgerissen wird. Von dieser Funkenbildung geht eine elektromagnetische Störstrahlung aus, die einen hochfrequenten Störanteil, der durch das sich bildende elektrostatische Feld erzeugt wird, und einen niederfrequenten Störanteil, de:r durch das sich bildende magnetische Feld erzeugt wird, aufweist. Durch die hier vorgenommene Verlagerung der Kommutatorlamellen 12 und des Bürstenhalters 18 in das Innere des Kommutatorkörpers 11 wird ein großer Teil dieser elektromagnetischen Störstrahlung durch den Kommutator selbst abgeschirmt. Der Deckel 15 sorgt dafür, dass die elektromagnetische Strahlung auch in Achsrichtung nicht oder nur bedämpft aus dem Kommutator austreten kann.When operating an electric motor equipped with such a commutator, e.g. B. a DC motor, sparks occur with each commutation, since during commutation the coils of the armature or rotor winding are short-circuited for a very short period of time by the commutator brushes 19 and then their short-circuit is opened again. This spark formation emits electromagnetic interference radiation, which has a high-frequency interference component, which is generated by the electrostatic field that is formed, and a low-frequency interference component, which is generated by the magnetic field that is formed. Due to the shifting of the commutator bars 12 and the brush holder 18 into the interior of the commutator body 11, a large part of this electromagnetic interference radiation is shielded by the commutator itself. The cover 15 ensures that the electromagnetic radiation cannot exit the commutator, or only in an attenuated manner, even in the axial direction.
Wird ein noch höher Entstörungsgrad gefordert, so wird - wie dies in Fig. 5 dargestellt ist - die äußere Mantelfläche 111 des Kommutatorkörpers 11 mit einer Schicht 23 versehen, die aufgrund ihrer Materialeigenschaft die elektromagnetische Störstrahlung noch weitergehend bedämpft. Eine solche Schicht 23 kann beispielsweise eine Metallhülse sein.If an even higher degree of interference suppression is required, then - as is shown in FIG. 5 - the outer lateral surface 111 of the commutator body 11 is provided with a layer 23 which, due to its material properties, further attenuates the electromagnetic interference radiation. Such a layer 23 can be a metal sleeve, for example.
In einem alternativen Ausführungsbeispiel ist für die verstärkte Bedämpfung der elektromagnetischen Störstrahlung der Kommutatorkörper 11 aus einem elektromagnetische Strahlung absorbierenden Material hergestellt. Ein solches Material wird beispielsweise dadurch gewonnen, dass demIn an alternative embodiment, the commutator body 11 is made of an electromagnetic radiation absorbing material for the increased attenuation of the electromagnetic interference radiation. Such a material is obtained, for example, by the
Kunststoff Beimengungen von magnetisch und/oder elektrisch leitfähigen Materialien zugegeben wird. Beispielsweise sind im Kunststoff Stahlfasern integriert oder ist dem Kunststoff Kohlenstoff in Form von Ruß beigemischt. Im ersten Fall werden die niederfrequenten Störanteile und im zweiten Fall die höherfrequenten Störanteile der elektromagnetischen Störstrahlung weitergehend bedämpft. Selbstverständlich können auch beide Materialkomponenten dem Kunststoff zugemischt werden. Der Kommutatorkorper 11 kann auch aus Metall bestehen, wobei zwischen dem Kommutatorkörper 11 und den Kommutatorlamellen 12 eine Isolierschicht vorzusehen ist.Plastic admixtures of magnetically and / or electrically conductive materials is added. For example, steel fibers are integrated in the plastic or carbon is added to the plastic in the form of soot. In the first case, the low-frequency interference components and in the second case the higher-frequency interference components of the electromagnetic interference radiation are further attenuated. Of course, both material components can also be mixed into the plastic. The commutator body 11 can also consist of metal, an insulating layer being provided between the commutator body 11 and the commutator bars 12.
Der Deckel 15 mit seiner störstrahlungsabsobierenden Eigenschaft wird aus dem gleichen Material wie vorstehend beschrieben hergestellt. The cover 15 with its interference-absorbing property is made of the same material as described above.
