With The supply energy obtained from the magnetic field becomes sensor and Transponder supplied.
Der Erfindung liegt die Aufgabe zugrunde, eine sehr wirksame und dabei einfach und kompakt aufgebaute dreidimensionale Wicklungsanordnung zur Erzeugung elektrischer Energie aus einem Magnetfeld anzugeben.The invention has for its object to be a very effective and simple and compact three-dimensional winding arrangement for generating electrical Specify energy from a magnetic field.
Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffes erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. This object is achieved in connection with the features of the preamble solved by the features specified in the characterizing part of claim 1.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß sich eine kompakte, reproduzierbare Geometrie der Wicklungsanordnung ergibt - d. h. es ergeben sich sehr gut reproduzierbare elektrische Werte (Induktivität, Kapazität), wodurch sich eine zusätzliche nachträgliche, kostenintensive Abstimmung (beispielsweise jeder einzelnen Wicklung bei einer Serienfertigung) erübrigt. Der für die Wicklungsanordnung verfügbare Raum wird optimal ausgenutzt, d. h. gegenüber konventionell gewickelten Wicklungen wird Raum eingespart. Die Wicklungsanordnung ist kostengünstig herstellbar.The advantages that can be achieved with the invention are, in particular, that one compact, reproducible geometry of the winding arrangement results - d. H. it result very reproducible electrical values (inductance, capacitance) an additional subsequent, cost-intensive coordination (e.g. everyone individual winding in series production). The one for the winding arrangement available space is used optimally, d. H. versus conventionally wound Space is saved in windings. The winding arrangement is inexpensive to manufacture.
Der allgemeine Vorteil einer dreidimensionalen Wicklung ist darin zu sehen, daß die dreidimensionale Wicklungsanordnung keine spezielle Ausrichtung in Abhängigkeit des zur Energieeinspeisung dienenden Magnetfeldes erfordert, um stets eine optimale "Energieausbeute" zu erzielen. Die dreidimensionale Wicklungsanordnung ist vielmehr stets in allen möglichen Positionen "automatisch" optimal bezüglich des Magnetfeldes ausgerichtet, was einen optimalen Empfang und eine optimale energetische Ausnutzung bei bewegten Sensoren und/oder Aktoren ermöglicht.The general advantage of a three-dimensional winding is that the three-dimensional winding arrangement no special orientation depending on the magnetic field serving for energy supply always requires an optimal To achieve "energy yield". The three-dimensional winding arrangement is rather always "automatically" optimal in all possible positions with regard to the magnetic field aligned what an optimal reception and an optimal energetic utilization with moving sensors and / or actuators.
Die vorgeschlagene dreidimensionale Wicklungsanordnung ist insbesondere geeignet für eine in der DE 199 26 799 A1 vorgeschlagene Anordnung zur drahtlosen Versorgung einer Vielzahl Sensoren mit elektrischer Energie unter Einsatz mindestens einer von einem mittelfrequenten Oszillator gespeisten Primärwicklung (Primärspule, Sendespule), wobei jeder Sensor mindestens eine zur Energieaufnahme aus einem mittelfrequenten Magnetfeld (Bereich von etwa 15 kHz bis etwa 15 MHz) geeignete Sekundärwicklung (Sekundärspule, Empfangsspule) aufweist. Die dort erforderlichen Sekundärwicklungen können sehr gut durch die vorgeschlagene dreidimensionale Wicklungsanordnung realisiert werden. Der Vorteil der stets "automatisch" optimalen Ausrichtung bezüglich des Magnetfeldes und damit der optimalen Energieausbeute ist insbesondere bei an beweglichen Maschinenkomponenten montierten Sensoren (Näherungssensoren) bedeutsam.The proposed three-dimensional winding arrangement is particularly suitable for an arrangement for wireless supply proposed in DE 199 26 799 A1 a variety of sensors with electrical energy using at least one primary winding fed by a medium-frequency oscillator (primary coil, transmitter coil), wherein each sensor has at least one for energy absorption from a medium frequency Magnetic field (range from about 15 kHz to about 15 MHz) suitable secondary winding (Secondary coil, receiving coil). The secondary windings required there can very well by the proposed three-dimensional winding arrangement will be realized. The advantage of always "automatically" optimal alignment with regard to the magnetic field and thus the optimal energy yield is particularly with sensors mounted on moving machine components (proximity sensors) significant.

In Fig. 1 sind Wicklungsträger und Kern der Wicklungsanordnung vor dem Zusammenbau
dargestellt. Der würfelförmige, zentrale Kern 1 aus magnetisch wirksamem Material
wird von einem aus zwei hohlen Halbwürfeln 2, 8 gebildeten Wicklungsträger abgedeckt.
Die beiden im wesentlichen symmetrischen Halbwürfel 2, 8 bestehen aus einem
elektrisch isolierenden Kunststoffmaterial.In Fig. 1, the winding carrier and core of the winding arrangement are before assembly
shown. The cube-shaped, central core 1 made of magnetically active material
is covered by a winding carrier formed from two hollow half-
Alle vier Kanten bzw. Ecken der Außenmantelfläche 3 des Halbwürfels 2 sind als erhabene
Kanten 4, 5, 6, 7 ausgebildet. In gleicher Weise sind auch alle vier Kanten der
Außenmantelfläche 9 des Halbwürfels 8 als erhabene Kanten 10, 11, 12, 13 ausgebildet.
Der Abstand zwischen einer Außenfläche einer erhabenen Kante 4, 5, 6, 7 und der
Außenmantelfläche 3 bzw. zwischen einer erhabenen Kante 10, 11, 12, 13 und der Außenmantelfläche
9 entspricht mindestens der Wicklungsstärke.All four edges or corners of the outer
Fig. 2 zeigt den montierten Wicklungsträger vor der Bewicklung. Der Kern 1 ist vollständig
von den beiden Halbwürfeln 2, 8 umschlossen. Vorzugsweise ist zwischen Kern
1 und Innenmantelflächen der Halbwürfel 2, 8 ein Klebstoff eingebracht, um einen
Schutz vor seitlicher Verschiebung sicherzustellen und eine robuste, rüttelsichere und
dauerhafte Fixierung zu gewährleisten. Alternativ hierzu sind die Innenflächen der
Halbwürfel 2, 8 mit flexiblen Noppen versehen, welche einen Toleranzausgleich zwischen
den Außenmaßen des Kerns und den Innenmaßen der Halbwürfel 2, 8 ermöglichen
und gleichzeitig eine Zentrierung und unverrückbare Fixierung des eingeschlossenen
Kerns sicherstellen. Eine weitere Alternative stellt das Einbringen eines elastischen
Schaumstoffmaterials oder eines sonstigen elastischen Materials zwischen Innenwandung
der Halbwürfel 2, 8 und Kern 1 dar.Fig. 2 shows the assembled winding carrier before the winding. Core 1 is complete

Wie gut in Fig. 2 zu erkennen ist, werden zwischen zwei erhabenen Kanten jeweils umlaufende Abstandsräume A, B, C zur Wicklungsführung der dreidimensionalen Wicklungsanordnung gebildet, und zwar
- Abstandsräume A zwischen den
10, 11, denKanten 4, 5, denKanten 6, 7 und denKanten 12, 13,Kanten - Abstandsräume B zwischen den
11, 12, denKanten 5, 6, denKanten 4, 7 und denKanten 10, 13,Kanten - Abstandsräume C zwischen den
4, 10, denKanten 5, 11, denKanten 6, 12 und denKanten 7,13.Kanten

10, 11,edges 4, 5,edges 6, 7 andedges 12, 13,edges - Spaces B between

4, 10,edges 5, 11,edges 6, 12 and edges 7.13.edges
Durch diese als durchgehende Wicklungspassagen dienenden Abstandsräume A, B, C wird jeweils die Wicklungsbreite der aufzubringenden Wicklungen festgelegt.Through these spacing spaces A, B, C serving as continuous winding passages the winding width of the windings to be applied is determined in each case.
Fig. 3 zeigt eine fertiggestellte dreidimensionale Wicklungsanordnung. Auf den Wicklungsträger
2 + 8 sind drei Wicklungen 14, 15, 16 aufgebracht, wobei die untere Wicklung
14 längs des Abstandsraumes C, die mittlere Wicklung 15 längs des Abstandsraumes
B und die obere Wicklung 16 längs des Abstandsraumes A verläuft. Über beispielsweise
an den erhabenen Kanten 5, 6, 7 angeordnete Wicklungsanschlüsse 17
erfolgt der elektrische Anschluß der drei Wicklungen 14, 15, 16. Diese als Kontaktstifte
ausgebildete Wicklungsanschlüsse 17 sind direkt mit Leiterbahnen einer Leiterplatte
verlötbar (SMD-Technik, Surface Mounted Device).3 shows a completed three-dimensional winding arrangement. On the
Alternativ ist der elektrische Wicklungsanschluß auch über Kontaktflächen an Stelle der gezeigten Kontaktstifte realisierbar.Alternatively, the electrical winding connection is also in place of the contact surfaces shown contact pins can be realized.
In diesem Zusammenhang stellt es einen besonderen Vorteil dar, wenn beispielsweise
die erhabenen Kanten 4, 5, 6, 7 an ihren nach außen gerichteten Flächen mit Rastnasen
versehen sind, welche ein Einrasten in eine Leiterplatte und somit die mechanische
Fixierung der dreidimensionalen Wicklungsanordnung an einer Leiterplatte ermöglichen.In this context, it is a particular advantage if, for example
the
Die gebildete dreidimensionale Wicklungsanordnung dient zur Erzeugung elektrischer
Energie aus einem Magnetfeld. Die Wicklungsachsen der drei Wicklungen 14, 15, 16
sind jeweils rechtwinklig zueinander angeordnet und schneiden sich in einem gemeinsamen
Punkt. Zur Erzeugung elektrischer Energie aus einem Magnetfeld bilden die
Wicklungen 14, 15, 16 zusammen mit Resonanzkondensatoren jeweils Serien-Resonanzkreise
oder Parallel-Resonanzkreise, welche vorzugsweise an Gleichrichter
angeschlossen sind. Die Gleichrichter sind sekundärseitig jeweils mit Stützkondensatoren
versehen. Die Gleichanschlüsse aller Gleichrichter sind in Serie mit einer zu speisenden
Last - beispielsweise einer Sensor-Meßeinheit oder einer Sensor-Elektronik
bzw. einer Ansteuereinheit eines Aktors - verschaltet.The three-dimensional winding arrangement formed is used to generate electrical
Energy from a magnetic field. The winding axes of the three
Auch wenn vorstehend stets von einer dreidimensionalen Wicklungsanordnung mit integriertem
zentralem Kern ausgegangen wird, ist auch eine dreidimensionale Wicklungsanordnung
ohne Kern realisierbar. Bei einer solchen dreidimensionalen Wicklungsanordnung
ist es nicht erforderlich, den würfelförmigen Wicklungsträger aus zwei
Bauteilen zusammenzusetzen, sondern der Wicklungsträger wird durch einen einteiligen
Würfel (beispielsweise aus einem massiven Kunststoffmaterial bestehend) mit erhabenen
Kanten 4, 5, 6, 7, 10, 11, 12, 13 an allen acht Ecken gemäß der in Fig. 2 gezeigten
Form gebildet.Even if above always from a three-dimensional winding arrangement with an integrated

realizable without core. With such a three-dimensional winding arrangement
it is not necessary to make the cube-shaped winding support from two
