Description
Unterteilter magnetisch leitender Körper. Aus magnetisch leitendem und isolierendem Pulver zusammengepreßte Körper finden als Magnetkerne für Induktionsspulen, vorzugsweise für Pupinspulen, verbreitete Anwendung.Divided magnetically conductive body. Made of magnetically conductive and insulating powder are used as magnetic cores for induction coils, preferably for pupin coils, widespread use.
Man hat vorgeschlagen, den einzelnen magnetischen Pulverteilchen zur Erzielung einer güten Raumerfüllung allseitig möglichst gleich ausgebildete, also am besten kugelförmige. Gestalt zu geben. Man erhält in diesem Falle bei einem bestimmten Preßdruck zwar verhältnismäßig dichte Körper, jedoch ist die magnetische Leitfähigkeit solcher Körper im Vergleich zu ihrer Dichte gering. In Abb. r ist der Querschnitt durch einen derartigen Körper dargestellt.It has been proposed to use the individual magnetic powder particles Achieving a good space filling on all sides as similarly trained as possible, that is preferably spherical. To give shape. In this case one obtains with a certain one Compression pressure is relatively dense body, but the magnetic conductivity such bodies low compared to their density. In fig.r is the cross section represented by such a body.
Man hat daher ferner vorgeschlagen, dünne Blättchen. zu verwenden, die mit ihrer Fläche in .der Feldrichtung liegen. und eine gute Raumdurchdringung, d. h. einen verhältnismäßig günstigen magnetischen Schluß gewährleisten.. Dieses Verfahren führt jedoch nicht zu dem gewünschten Erfolg, da, sich feines blättchenförmiges Pulver nur schwer zu genügend dichten. Körpern zusammenpressen läßt. In Abb. a ist der Querschnitt durch einen aus blättchenförmigem Pulver gepreßten Körper dargestellt.It has therefore also been proposed to use thin leaflets. to use, which lie with their area in the direction of the field. and good space penetration, d. H. ensure a relatively favorable magnetic closure .. This However, the method does not lead to the desired success because it is fine flaky Powder difficult to dense enough. Bodies pressed together. In fig a is the cross-section through a body pressed from sheet-like powder.
Die Erfindung betrifft einen aus Einzelelementen zusammengesetzten Körper, der einerseits eine genügende Dichte und andererseits einen hinreichenden Schluß in der Feldrichtung, d. h. selbst für verhältnismäßig niedrige Preßdrucke eine gute magnetische Leitfähigkeit besitzt. Erfindungsgemäß besteht der Körper zum größten Teil aus allseitig möglichst gleichmäßig ausgebildeten Teilchen, die jedoch unter sich durch ein dichtes Flechtwerk von feinen Blättchen eng verbunden sind. In Abb.3 ist der Querschnitt durch einen Pulverkern gemäß der Erfindung dargestellt.The invention relates to a composite of individual elements Body that on the one hand has a sufficient density and on the other hand a sufficient one End in the field direction, d. H. even for relatively low press pressures has good magnetic conductivity. According to the invention, the body consists for the most part from all sides as uniformly formed particles as possible, the but closely connected to each other by a dense network of fine leaves are. In Fig.3 the cross section through a powder core according to the invention is shown.
Der Gedanke der Erfindung läßt sich sinngemäß auch auf andere als pulverförmige Systeme anwenden, beispielsweise auf 3>Querdrahtkerne«, bei denen die etwa runden Drahtstückchen mit feinen magnetischen Bändchen oder blättchenförmigem Pulver verflochten werden.The idea of the invention can be applied analogously to other than Use powdery systems, for example on 3> cross wire cores, where the roughly round pieces of wire with fine magnetic ribbons or leaflet-shaped Powder to be intertwined.
Die Abb. q. zeigt einen Querdxahtkern ohne Verflechtung, Abb. 5 einen solchen Kern mit Verflechtung durch blättchenförmiges Pulver.Fig.q. shows a transverse seam core without interlacing, Fig. 5 shows a such a core with interweaving by flaky powder.
