Abstract
Description
Die Erfindung betrifft eine Anordnung einer Entstörschaltung für einen Gleichstrommotor mit zwei Anschlusskontakten, wobei die Entstörschaltung zumindest je einen Ableitkondensator zur elektrischen Verbindung der zwei Anschlusskontakte des Gleichstrommotors mit dem Motorgehäuse, und je eine Entstördrossel zur elektrischen Verbindung der zwei Anschlusskontakte mit der Ansteuerelektronik des Gleichstrommotors aufweist.The The invention relates to an arrangement of a suppression circuit for a DC motor with two connection contacts, with the suppression circuit at least one each Ableitkondensator for electrical connection the two terminals of the DC motor with the motor housing, and one each suppression choke for the electrical connection of the two terminal contacts with the control electronics of DC motor has.
Es ist bekannt, dass durch die Verwendung von Elektromotoren oder anderen elektronischen Systemen Störstrahlungen entstehen, die den Betrieb anderer elektronischer Systeme negativ beeinflussen oder beispielsweise den Rundfunkempfang oder Funkverkehr erschweren. Gleichzeitig existiert auch eine Empfindlichkeit des Systems selbst gegen die Störabstrahlung anderer elektronischer Systeme. Daher ist es insbesondere in der Automobilindustrie üblich, die elektromagnetische Verträglichkeit von elektronischen Bauteilen nachweisen zu müssen.It is known to be through the use of electric motors or others electronic systems interference radiation arise, which negatively affects the operation of other electronic systems influence or, for example, the radio reception or radio communication difficult. At the same time there is also a sensitivity of the Systems themselves against the disturbance radiation other electronic systems. Therefore, it is especially in the Automotive industry usual, the electromagnetic compatibility to prove of electronic components.
So
wird in der
Inwieweit eine besondere Anordnung der einzelnen Bauteile einer Entstörschaltung zu einer weiteren Verbesserung der Störstrahlung führt, wurde bisher nicht untersucht.To what extent a special arrangement of the individual components of a suppression circuit led to a further improvement of the interference, was not examined yet.
Es ist daher Aufgabe der Erfindung, eine Anordnung einer Entstörschaltung zu schaffen, durch die die elektromagnetische Verträglichkeit zusätzlich verbessert werden kann, ohne zusätzliche Bauteile verwenden zu müssen.It It is therefore an object of the invention to provide an arrangement of an interference suppression circuit to create, through which the electromagnetic compatibility additionally improved can be without additional To use components.
Diese Aufgabe wird dadurch gelöst, dass die mit je einem der Anschlusskontakte des Gleichstrommotors elektrisch verbundene Entstördrossel und der mit demselben Anschlusskontakt des Gleichstrommotors verbundene Ableitkondensator jeweils derart am Gleichstrommotor in unmittelbarer Nähe zueinander angeordnet sind, dass die elektromagnetischen Feldlinien der Entstördrossel senkrecht zu den elektromagnetischen Feldlinien des mit dem gleichen Anschlusskontakt verbundenen Ableitkondensators liegen. Durch eine derartige Anordnung wird ein erheblich verbesserter Störgrad des Gleichstrommotors erreicht. Dies ist darauf zurückzuführen, dass eine induktive Kopplung zwischen den Bauteilen Entstördrossel und Ableitkondensator verhindert wird.These Task is solved by that with each one of the terminals of the DC motor electrically connected suppression choke and the one connected to the same terminal of the DC motor Conduction capacitor in each case so on the DC motor in the immediate Close to each other are arranged so that the electromagnetic field lines of the suppression choke perpendicular to the electromagnetic field lines of the same Connection contact connected Ableitkondensators lie. By a Such arrangement will significantly improve the degree of interference DC motor achieved. This is due to the fact that an inductive coupling between the components suppression choke and bypass capacitor is prevented.
Vorzugsweise ist die Entstörschaltung achssymmetrisch aufgebaut, wobei durch die Symmetrie eine zusätzliche, die Abstrahlung dämpfende Wirkung erzielt wird.Preferably is the suppression circuit axisymmetric, whereby due to the symmetry an additional, the radiation damping Effect is achieved.
In einer weiterführenden Ausführungsform sind von den Entstördrosseln zur Ansteuerelektronik verlaufende Leiterbahnen parallel und in unmittelbarer Nähe zueinander angeordnet. Durch den hier vorhandenen engen Abstand wird diese abstrahlungsdämpfende Wirkung noch einmal verstärkt. Insbesondere heben sich die elektromagnetischen Felder der beiden Leiterbahnen weitestgehend gegenseitig auf.In a continuing Embodiment are from the suppression chokes to the control electronics running tracks parallel and in in close proximity to arranged to each other. Due to the existing close distance This is radiation-damping Effect reinforced again. In particular, the electromagnetic fields of the two cancel each other out Tracks are largely mutually exclusive.
Des Weiteren wurde festgestellt, dass eine zusätzliche Verbesserung der Entstörung dadurch erreicht wird, dass die Entstördrosseln in einem Winkel von 70° bis 140° zueinander angeordnet sind. Dies führt wiederum zu einer zumindest teilweisen Entkopplung beispielsweise zwischen den beiden Entstördrosseln.Of It has also been found that this achieves an additional improvement of the suppression that is the suppression chokes at an angle of 70 ° to 140 ° to each other are arranged. this leads to turn to an at least partial decoupling, for example between the two suppression chokes.
Eine weitere Verbesserung wird dadurch erzielt, dass ein dritter Ableitkondensator die beiden Anschlusskontakte elektrisch verbindet. Dies führt zu einer verbesserten Entstörung des Gleichstrommotors insbesondere im unteren Frequenzbereich.A Further improvement is achieved in that a third leakage capacitor the two connection contacts electrically connects. This leads to a improved filtering of the DC motor, especially in the lower frequency range.
All diese Ausführungen führen zu einer deutlich verbesserten elektromagnetischen Verträglichkeit des Gleichstrommotors, so dass dieser in einem Kraftfahrzeug verwendet werden kann. Erstmalig wird somit eine Verbesserung der Störabstrahlung durch eine optimierte Anordnung der Entstörbauteile zueinander offenbart.Alles these designs to lead to a significantly improved electromagnetic compatibility of the DC motor, so this used in a motor vehicle can be. For the first time thus an improvement of the noise emission by discloses an optimized arrangement of the suppression components to each other.
Ein Ausführungsbeispiel ist in den Zeichnungen dargestellt und wird nachfolgend beschrieben.One embodiment is shown in the drawings and will be described below.

Erwähnt sei an dieser Stelle auch, dass das axiale Spiel des Motors so klein wie möglich gewählt werden sollte, da ansonsten der Funkenabriss am Kollektor größer wird und somit die Dämpfung beeinträchtigt wird.Mention should be made at this point too, that the axial play of the engine is so small as possible to get voted should, otherwise the spark arrester at the collector gets bigger and thus the damping impaired becomes.

Wie beiden Figuren zu entnehmen ist, ist eine symmetrische, insbesondere achssymmetrische Gestaltung der Entstörschaltung ebenfalls zur induktiven Entkopplung der gegenüberliegenden Bauteile zu empfehlen.As two figures is to be seen is a symmetrical, in particular Axisymmetric design of the suppression circuit also for inductive Decoupling the opposite To recommend components.

Eine derartig ausgebildete Entstörschaltung mit einer Anordnung der einzelnen Bauteile zueinander, wie sie in den Ausführungen dargestellt sind, verbessert den erreichbaren Entstörgrad erheblich, ohne zusätzliche Bauteile verwenden zu müssen. Dies wird insbesondere durch eine induktive Entkopplung der Teile zueinander erreicht. So wird eine sehr gute Dämpfung von Spannungsspitzen erzielt.A such trained interference suppression circuit with an arrangement of the individual components to each other, as in the versions are shown, the achievable degree of interference significantly improves, without additional To use components. This is in particular by an inductive decoupling of the parts to each other reached. This is a very good damping of voltage spikes achieved.
