Es ist bekannt, bei Gldchstrommaschinen zur Einstellung des Luftspaltes zwischen dem Joch und den Polschenkeln oder Wendepolen Eisenbleche 'einzulegen, um den Luftspalt auf einen bestimmten Wert zu bringen bzw. die magnetische Charakteristik zu beeinflussen. It is known in Gldchstrommaschinen to adjust the air gap between the Yoke and the pole legs or reversing poles 'iron sheets' insert around the air gap to bring to a certain value or to influence the magnetic characteristics.
Bei Wechselstrommasc'hinen ist die Anwendung· derartiger magnetischer ZwischenlagenIn the case of AC machines, the application such magnetic spacers
nicht möglich, weil infolge des Wechselfeides in den quer zu den Kraftlinien liegenden Eisenzwischenlagen starke Verluste und daher Erwärmungen auftreten würden. Erfkidungsgemäß werden nun bei derartigen Maschinen an Stelle von einzelnen Blechen Körper aus magnetisierbarem Material verwendet, bei denen das magnetisch leitende Material, beispielsweise Eisenspäne, in fein verteilter Form in einen Isolierstoff· eingebettet ist. Die Anwendung derartiger Zwischenlagen ermöglicht es, bei Wechselstrommaschinen in beliebiger Weise den Luftspalt zu verändern, was insbesondere bei den Wendepolen zur Erzielung einer günstigen Kommutierung erwünscht ist.not possible because as a result of the alternating field in the transverse to the lines of force Iron liners heavy losses and therefore warming would occur. According to the invention are now used in such machines instead of individual sheets Body made of magnetizable material used, in which the magnetically conductive Material, for example iron filings, embedded in a finely divided form in an insulating material is. The use of such intermediate layers makes it possible in AC machines to change the air gap in any way, which is particularly important with the Reversing poles to achieve a favorable commutation is desirable.
Der Erfindungsgedanke kann aber auch bei Gleichstrommaschinen Anwendung finden, beispielsweise um die Zeitkonstante des magnetischen Feldes besonders klein zu halten.The idea of the invention can also be used in DC machines, for example by the time constant of the magnetic field to be particularly small keep.
An sich ist die Verwendung von Isoliermassen, die ein magnetisch gut leitendes Material in pulverförmiger Form enthalten, als Baustoff bei elektrischen Maschinen und Apparaten für höhere Frequenzen bereits bekannt. Dort handelt es sich jedoch nicht um die Gesichtspunkte, auf die es beim Erfindungsgegenstand ankommt.In itself, the use of insulating compounds, which have good magnetic conductivity Contains material in powder form as a building material for electrical machines and Apparatus for higher frequencies already known. However, it is not there about the points of view on which the subject matter of the invention applies arrives.
Im folgenden soll die Erfindung an Hand eines Ausführungsbeispieles näher erläutert werden.The invention is explained in more detail below using an exemplary embodiment will.
Fig1, ι zeigt den Ständer eines Wechselstrommotors, der aus lamellierten Blechen aufgebaut ist.Fig 1 , ι shows the stator of an AC motor, which is constructed from laminated metal sheets.
ι ist das Joch, 2 sind die Hauptpole. 3 sind die Wendepole. Zwischen den Wendepolen und dem Joch sind Leisten 4-aus, Isoliermasse angeordnet, welche in fein verteilter Form Eisenpulver oder ein ähnliches, magnetisch gut leitendes Material enthält.ι is the yoke, 2 are the main poles. 3 are the reversing poles. Between the reversing poles and the yoke there are 4-made strips of insulating compound arranged, which in finely divided form iron powder or a similar, Contains magnetically good conductive material.
