Description
Die Erfindung geht aus von einer Anordnung zur Überwachung der Abnutzung einer Bürste des Schleifbahn- oder Kommutatorsystems einer elektrischen Maschine, wie sie beispielsweise aus der
Eine weitere bekannte Vorrichtung zur kontaktlosen Überwachung der Bürsten einer elektrischen Maschine ist in der
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zur Überwachung der Abnutzung einer Bürste einer elektrischen Maschine anzugeben, welche betriebssicher arbeiten, mit geringem Kostenaufwand herstellbar sind und keinen oder nur einen geringen zusätzlichen Bauraum in der Maschine erfordern, so dass sie in herkömmliche Bürstensysteme integrierbar oder gegen diese austauschbar sind. Dies wird erreicht durch die kennzeichnenden Merkmale der übergeordneten Vorrichtungs- und Verfahrensansprüche.The invention has for its object to provide an apparatus and a method for monitoring the wear of a brush of an electric machine, which operate reliable, can be produced at low cost and require little or no additional space in the machine, so that they are in conventional Brush systems can be integrated or exchanged for them. This is achieved by the characterizing features of the parent device and method claims.
Zur Erzielung eines deutlich messbaren Impedanzunterschiedes im Messsignal entsprechend dem fortschreitenden Bürstenverschleiß ist es zweckmäßig, wenn die Grundsubstanz der Bürste eine deutlich unterschiedliche, vorzugsweise geringere elektrische Leitfähigkeit γ1 aufweist als der in die Bürste integrierte Messabschnitt. Zweckmäßigerweise besteht hierbei die Grundsubstanz der Bürste aus einem ungefüllten oder aus einem metallgefüllten Kohlematerial mit einem elektrischen Leitwert γ1 im Bereich zwischen etwa 0,05 und 20 MS/m, während der Einsatz in der Bürste zur deutlichen Abgrenzung des vom Sensor gemessenen Impedanzwertes Z aus Metall, vorzugsweise aus Kupfer mit einem elektrischen Leitwert γ2 von 56 bis 57 MS/m besteht. Bei der Verwendung gut leitfähiger Bürsten kann das Messprinzip jedoch auch umgekehrt werden, indem als Material für den in die Bürste integrierten Abschnitt mit abweichender elektrischer Leitfähigkeit γ2 gegenüber der Grundsubstanz der Bürste ein Dielektrikum verwendet wird, so dass die Impedanz Z in diesem Messbereich deutlich abfällt gegenüber dem zulässigen Verschleißbereich der Bürste. Weiterhin kann es insbesondere bei Verwendung der Erfindung in Kommutatormotoren vorteilhaft sein, wenn der in die Bürste integrierte Abschnitt mit abweichender elektrischer Leitfähigkeit gegenüber der Grundsubstanz der Bürste elektrisch isoliert und nicht von dem Arbeitsstrom der Bürste durchflossen ist, um den Einfluss des Betriebsstromes auf die Impedanzmessung zu verhindern.To achieve a clearly measurable impedance difference in the measurement signal corresponding to the progressive brush wear, it is expedient if the base substance of the brush has a significantly different, preferably lower electrical conductivity γ1 than the measuring section integrated in the brush. Appropriately, in this case, the base substance of the brush consists of an unfilled or of a metal-filled carbon material with an electrical conductance γ1 in the range between about 0.05 and 20 MS / m, while the use in the brush for clear demarcation of the impedance Z measured from the sensor made of metal , preferably made of copper with an electrical conductivity γ2 of 56 to 57 MS / m. However, when using brushes of good conductivity, the measuring principle can also be reversed by using a dielectric material as the material for the section with deviating electrical conductivity γ2 that is integrated into the brush, so that the impedance Z clearly drops in this measuring range the permissible wear area of the brush. Furthermore, it can be advantageous in particular when using the invention in commutator motors, when the integrated into the brush section with different electrical conductivity with respect to the ground substance of the brush electrically insulated and not flowed through by the working current of the brush to the influence of the operating current to the impedance measurement prevent.
Unter fertigungstechnischen Gesichtspunkten kann es vorteilhaft sein, wenn der Abschnitt mit dem von der Grundsubstanz der Bürste abweichenden elektrischen Leitwert getrennt von der Bürste hergestellt und durch eine formschlüssige, vorzugsweise schwalbenschwanzförmige Verbindung nachträglich auf der Bürste montiert wird. Die Verbindung zwischen dem Einsatz und der Bürste kann auch durch Kleben hergestellt werden, sodass hinsichtlich der Gestaltung der zu verbindenden Teile kein oder nahezu kein zusätzlicher Aufwand entsteht. Andererseits kann auch eine formschlüssige Verbindung durch eine Klebeverbindung zusätzlich gesichert werden. Bei starken mechanischen Beanspruchungen der Bürste, beispielsweise in Antrieben mit starken Vibrationen, ist eine Nietverbindung zwischen der Bürste und dem Einsatz vorteilhaft. Bei Verwendung geeigneter Materialien für die Grundsubstanz der Bürste und für den Abschnitt mit abweichender elektrischer Leitfähigkeit ist jedoch auch die Herstellung der Bürste in einem Arbeitsgang, vorzugsweise durch gemeinsames Verpressen der unterschiedlichen Materialien möglich.From a manufacturing point of view, it may be advantageous if the section made with the deviating from the basic substance of the brush electrical conductance separately from the brush and subsequently mounted by a positive, preferably dovetailed connection on the brush. The connection between the mission and the brush can also be made by gluing, so that with regard to the design of the parts to be joined no or almost no additional effort. On the other hand, a positive connection can be additionally secured by an adhesive connection. In the case of heavy mechanical stresses on the brush, for example in drives with strong vibrations, a riveted connection between the brush and the insert is advantageous. When using suitable materials for the base substance of the brush and the section with different electrical conductivity but also the production of the brush in a single operation, preferably by co-pressing the different materials is possible.
In konstruktiver Hinsicht ist es zweckmäßig, wenn der Impedanzsensor von der Auswerteeinheit baulich getrennt und als kompakte Einheit direkt in den Bürstenhalter integriert ist. In die Auswerteeinheit kann vorteilhafterweise ein Signalgeber für die Speisung des Sensors mit einer Wechselspannung U integriert werden. Eine derartige Anordnung ist konstruktiv sehr variabel und lässt sich leicht ohne nennenswerten zusätzlichen Platzbedarf im Bürstenbereich der Maschine einbauen.In terms of design, it is expedient if the impedance sensor is structurally separated from the evaluation unit and integrated as a compact unit directly into the brush holder. In the evaluation unit advantageously a signal generator for the supply of the sensor with an AC voltage U can be integrated. Such an arrangement is structurally very variable and can be easily installed without significant additional space in the brush area of the machine.
Das erfindungsgemäße Verfahren zur Überwachung der Abnutzung einer Bürste des Schleifbahn- oder Kommutatorsystems einer elektrischen Maschine zeichnet sich dadurch aus, dass ein ortsfest angeordneter Impedanzsensor mit einer Wechselspannung U oder einer Signalfolge im Frequenzbereich von 100 kHz bis 30 MHz, vorzugsweise in einem Bereich von 500 kHz bis 3MHz gespeist wird. Entsprechend dem Leitwert γ1,γ2 eines dem Sensor benachbarten Abschnittes der verschiebbaren Bürste liefert der Sensor hieraus ein veränderliches Impedanzsignal als Maß für die verbleibende Bürstenlänge an eine Auswerteeinheit. Dieses Verfahren ist bei geringem zusätzlichem Aufwand sehr betriebssicher und gewährleistet ein mit einfachen Mitteln leicht erfassbares Messsignal für die Abnützung der Bürste, sodass herkömmliche Schwierigkeiten durch einen unvorhergesehenen Bürstenausfall vermieden werden. In einigen Applikationen wird hierbei die Bürste durch das Ausgangssignal der Auswerteeinheit von der Spannungsversorgung abgeschaltet, sobald ein vorgegebener Signalpegel überschritten wird. Hierdurch ist sichergestellt, dass in kritischen Anwendungen Folgeschäden sicher vermieden werden.The inventive method for monitoring the wear of a brush of the slideway or Kommutatorsystems an electrical machine is characterized in that a fixedly arranged impedance sensor with an AC voltage U or a signal sequence in the frequency range of 100 kHz to 30 MHz, preferably in a range of 500 kHz is fed to 3MHz. In accordance with the conductance γ1, γ2 of a section of the displaceable brush adjacent to the sensor, the sensor supplies therefrom a variable impedance signal as a measure of the remaining brush length to an evaluation unit. This method is very reliable with little additional effort and ensures an easily detectable by simple means measuring signal for the wear of the brush, so that conventional difficulties caused by an unforeseen brush failure can be avoided. In some applications, the brush is turned off by the output of the evaluation of the power supply, as soon as a predetermined signal level is exceeded. This ensures that consequential damage is safely avoided in critical applications.

In Figur 1 ist mit 10 ein Schleifring oder Kommutator einer nicht weiter dargestellten elektrischen Maschine bezeichnet, welcher über eine Bürste 12 und eine Litze 13 mit dem Pluspol 14 eines Gleichspannungsnetzes verbunden ist. Die Bürste 12 ist in einem Bürstenhalter 18 zum Kommutator oder Schleifring 10 hin längsverschiebbar gehalten und wird durch eine Feder 20, welche auf einem Fortsatz 22 der Bürste 12 zentriert ist, an den Schleifring oder Kommutator 10 angedrückt. Der Minuspol 16 des Gleichspannungsnetzes ist an eine weitere, nur schematisch eingezeichnete Bürste angeschlossen, welche gleichartig ausgebildet und gehalten ist.In Figure 1, 10 denotes a slip ring or commutator of an electric machine, not shown, which is connected via a
Die Überwachungsvorrichtung für die Abnutzung der Bürste 12 weist eine kontaktlose Sensoreinrichtung auf in Form eines Impedanzsensors 24 mit einer Spule 26 und einem E-förmigen Magnetkern 28, welcher ortsfest unmittelbar der Bürste 12 benachbart angeordnet ist und zur Bürste hin keinen geschlossenen Magnetkreis aufweist. Der Impedanzsensor 24 ist mit einer Auswerteeinheit 30 verbunden, welche eine Impedanzmesseinrichtung 32 sowie einen Signalgeber 34 enthält zur Speisung der Spule 26 mit einer hochfrequenten Spannung U. Die dem Impedanzsensor 24 unmittelbar benachbarte, in dem Bürstenhalter 18 längsverschiebbar geführte Bürste 12 ist als Zweikomponentenbauteil ausgeführt. Sie besteht im Wesentlichen aus einem ungefüllten oder teilweise metallgefüllten Kohlematerial mit einer elektrischen Leitfähigkeit γ1 im Bereich zwischen etwa 0,05 und 20 MS/m. Im oberen, von der Kontaktfläche zum Schleifring oder Kommutator 10 abgewandten Abschnitt 36 ist in den dem Impedanzsensor 24 benachbarter Außenbereich der Bürste 12 ein Einsatz 38 eingefügt aus einem Material mit deutlich höherer elektrischer Leitfähigkeit γ2, zum Beispiel ein Einsatz aus Kupfer mit einer Leitfähigkeit von 56 bis 57 MS/m. Dieser Einsatz ist durch eine dünne Isolierschicht 40 gegenüber der Grundsubstanz 35 der Bürste 12 isoliert.The monitoring device for the wear of the
Durch die von dem Signalgeber 34 in die Spule 26 eingespeiste hochfrequente Spannung U werden in der Bürste 12 Wirbelströme erzeugt, deren Höhe von der Leitfähigkeit γ des Bürstenmaterials abhängt. Unterschiedliche Wirbelströme in der Bürste beeinflussen die Impedanz Z des Sensors 24, da die Feldlinien der Spule 26 teilweise in der Bürste 12 verlaufen. Diese Tatsache macht sich die erfindungsgemäße Überwachungsvorrichtung, beziehungsweise das erfindungsgemäße Überwachungsverfahren für die Abnutzung der Bürste zunutze. Mit zunehmender Abnutzung der Bürste 12 gelangt der Einsatz 38, beziehungsweise der Abschnitt 36 mit dem Material mit höherer elektrischer Leitfähigkeit γ2 in den Bereich der Feldlinien des Sensors 24. Hierdurch nehmen die von der Spule 26 erzeugten Wirbelströme zu und mit ihnen die Impedanz Z des Sensors 24, welche in der Messeinrichtung 32 der Auswerteeinheit 30 erfasst und als vorzugsweise digitales Signal 48 zum Beispiel an eine nicht dargestellte Diagnoseeinheit ausgegeben wird.By the high-frequency voltage U fed by the
Dieser Sachverhalt ist in den Abbildungen der Figuren 2 und 3 näher dargestellt. Figur 2 zeigt schematisch die Größe der durch die Messeinrichtung 32 erfassten frequenzabhängigen Impedanz Z im Abschnitt I am Ende der Bürstenlebensdauer, im Abschnitt II für den Bereich des Eintritts des Einsatzes 38 in den Erfassungsbereich des Sensors 24 bis zur vollständigen Überdeckung des Messbereiches durch den Einsatz 38, und im Abschnitt III den Wert der vom Sensor 24 gemessenen
Impedanz Z einer neuwertigen Bürste, solange der Abschnitt 36, beziehungsweise der Einsatz 38 keinen Einfluss auf die Impedanz des Sensors 24 hat.This situation is shown in more detail in Figures 2 and 3. FIG. 2 schematically shows the size of the frequency-dependent impedance Z detected by the
Impedance Z of a new brush, as long as the
Entsprechend den Kennlinienabschnitten I und III in Figur 2 sind in den Figuren 3a und 3b die Verläufe der vom Signalgeber 34 gelieferten Spannung U und des Signalstromes I dargestellt, wobei der Kurvenverlauf in Figur 3a dem Abschnitt I für eine stark abgenutzte Bürste und der Verlauf in Figur 3b dem Abschnitt III für eine neuwertige Bürste entspricht. Der Unterschied ΔI entspricht jeweils dem fortgeschrittenen Verschleiß der Bürste.Corresponding to the characteristic sections I and III in FIG. 2, the curves of the voltage U and the signal current I supplied by the
Die Figuren 4 und 5 zeigen beispielhaft zwei unterschiedliche Bauformen einer Zweikomponentenbürste, welche jeweils einen Einsatz 38 mit gegenüber der Grundsubstanz 35 deutlich erhöhter elektrischer Leitfähigkeit γ2 aufweisen. Bei der Ausführungsform gemäß Figur 4 ist der Einsatz 38 mit einem passend geformten Abschnitt 42 in eine schwalbenschwanzförmige Nut 44 des Bürstengrundkörpers einschiebbar. Die äußeren Abmessungen des Einsatzes 38 aus dem Material höherer Leitfähigkeit γ2 sind auf die Abmessungen der Bürste abgestimmt, so dass diese ungehindert ohne bauliche Veränderung längsverschiebbar in dem Bürstenhalter 18 aufgenommen werden kann. Entsprechendes gilt für die Figur 5, welche einen durch eine Nietung 46 mit der Grundsubstanz 35 der Bürste 12 verbundenen Einsatz 38 aufweist. Auch hierbei bleibt die äußere Geometrie der Bürste unverändert. Die Isolation zwischen dem Einsatz 38 und der Grundsubstanz 35 der Bürste erfolgt jeweils durch eine geeignete isolierende Beschichtung des Einsatzes 38, auf deren Darstellung in den Figuren 4 und 5 verzichtet worden ist.FIGS. 4 and 5 show, by way of example, two different designs of a two-component brush, each of which has an
Die erfindungsgemäße Überwachungsvorrichtung, beziehungsweise das erfindungsgemäße Überwachungsverfahren ermöglichen somit eine dauernde Überwachung des Bürstenverschleißes bei Elektromotoren in Antriebs- oder Generatorapplikationen, wobei insbesondere ein durch unterschiedliche Betriebsbedingungen verursachter unterschiedlicher Verschleiß der Bürsten rechtzeitig vor deren Ausfall festgestellt werden kann. Dies gilt beispielsweise für den Einsatz im Automobilbereich, wo ein unterschiedlicher Betrieb und/oder unterschiedliche Umweltbedingungen, beispielsweise durch Verschmutzung, eine stark verkürzte Lebensdauer der Bürsten von elektrischen Maschinen verursachen können. Insbesondere wird eine gestufte Vorwarnung durch ein optisches, akustisches oder sonstiges Warnsignal ermöglicht, welche dem Benutzer die Zeit und die Möglichkeit gibt, absehbaren Störungen rechtzeitig vorzubeugen. Hierdurch können erhebliche Folgekosten durch einen überraschenden Ausfall der elektrischen Maschine und insbesondere auch hierdurch verursachte Risiken, beispielsweise im Verkehr, rechtzeitig und mit Sicherheit vermieden werden.The monitoring device according to the invention, or the monitoring method according to the invention thus enable a continuous monitoring of brush wear in electric motors in drive or generator applications, in particular caused by different operating conditions different wear of the brushes can be found in good time before their failure. This applies, for example, for use in the automotive sector, where a different operation and / or different environmental conditions, such as pollution, can cause a greatly shortened life of the brushes of electrical machines. In particular, a gradual warning is made possible by a visual, audible or other warning signal, which gives the user the time and the opportunity to prevent foreseeable disruptions in good time. This can result in significant follow-up costs Surprising failure of the electrical machine and in particular also caused thereby risks, for example in traffic, timely and certainly avoided.
