Description

Gegenstand, der Erfindung ist ein vielpoliger festliegender Anker für Kleinstromerzeuger, insbesondere für Fahrradbeleuchtungs- und Taschenlampenzwecke, d. h. für äußerst kleine und leicht auszubildende Stromerzeuger. The subject matter of the invention is a multi-pole fixed armature for small power generators, especially for bicycle lighting and flashlight purposes, d. H. for extremely small and easy to train power generators.

Es sind bereits ■ Anker vorgeschlagen worden, bei welchen durch die Pole eine einzige Spule induziert wird, und deren magnetischer Teil durch Biegen von einzelnen Blechstreifen mit dem Luftspalt zugekehrter Breitseite gebildet wird.There have already been proposed ■ anchors in which a single through the poles Coil is induced, and its magnetic part by bending individual sheet metal strips is formed with the air gap facing broadside.

Um ieine hohe Leistung solcher Stromerzeuger zu erzielen, muß dem magnetischen Fluß ein großer Querschnitt zur Verfugung stehen, insbesondere auch im Luftspalt, welcher jeweils die Stelle größten Widerstandes bildet. Um dies zu erreichen, werden erfindungsgemäß jeweils zwei längs der Breitseite dicht aneinander liegende Blechstreifen gleichförmig gebogen, aber zur gleichnamigen Polbildung an ihren Enden auseinandergehalten, derart, daß die Feldmagnetpole zwischen den PoI-enden der Blechstreifen umlaufen können. Hierdurch wird erreicht, daß dem Luftspalt ein doppelt so großer Querschnitt zur Verfügung steht, zugleich mit einer derartig vollständigen Ausnutzung der ineinandergreifenden Polflächen, daß Streuungsflüsse auf den ο Kleinstwert herabgesetzt werden.In order to achieve a high output of such power generators To achieve this, the magnetic flux must have a large cross section stand, especially in the air gap, which forms the point of greatest resistance. In order to achieve this, according to the invention, two each are sealed along the broad side Adjacent sheet metal strips curved uniformly, but to form poles of the same name held apart at their ends so that the field magnetic poles between the PoI ends the sheet metal strips can circulate. This ensures that the air gap a cross-section twice as large is available, at the same time with such a complete one Exploitation of the interlocking pole faces that scatter fluxes on the ο the minimum value can be reduced.

Die aneinanderliegenden Bleche können inThe adjacent sheets can be in

bekannter Weise aus Blechstreifen bestehen, die ein Mehrfaches der Polbreite bilden und durch Zusammenfalten auf die* erforderliche Polbreite zurückgeführt sind.known way consist of sheet metal strips that form a multiple of the pole width and are brought back to the * required pole width by folding.

Die Zeichnung zeigt beispielsweise eine Ausführungsform des Erfindungsgegenstandes im axialen Schnitt.The drawing shows, for example, an embodiment of the subject matter of the invention in axial section.

Ein Feldmagnet 1 dreht sich um dieAchse 2, während der Anker 3 mit seiner einzigen Spule 4 festliegt.A field magnet 1 rotates around the axis 2, while the armature 3 with its only one Coil 4 is fixed.

Jeder Pol, z. B. 5, des Feldmagneten läuft zwischen den Polenden, z. B. 6 und 7, der Ankerblechstreifen, so daß jeweils zwei parallel geschaltete Luftspalten, z. B. 8 und 9, entstehen. Diesen Luftspalten gegenüber liegt jeweils die Breitseite der an diesen Stellen auseinandergehaltenen, aber sonst dicht aneinander liegenden und gleichförmig gebogenen Blechstreifen, was eine äußerst einfache, billige und leichte Konstruktion ermöglicht.Each pole, e.g. B. 5, the field magnet runs between the pole ends, z. B. 6 and 7, the Anchor plate strips, so that two air gaps connected in parallel, for. B. 8 and 9 arise. Opposite these air gaps is the broad side of the one held apart at these points, but otherwise close to one another lying and uniformly curved sheet metal strips, which is an extremely simple, cheap and lightweight construction allows.
