Description

Die Erfindung bezieht sich auf Dauermagnetsysteme mit Polschuhen, insbesondere für Zünd- und Lichtstromerzeuger. Bisher war es üblich, die Polschuhe an den Magneten durch Schrauben o.dgl. zu befestigen, oder auch die Polschuhe an einem -das ganze Magnetsystem umschließenden Gehäuse festzumachen und gegen die Magnete anzupressen. Zum Befestigen der Polschuhe im Gehäuse einer magnetelektrischen Zündmaschine ist schon vorgeschlagen worden, das Gehäuse van Schwalbenschwänze der Polschuhe herumzugießen. Diese bekannten Konstruktionen haben alle den Nachteil, daß eine gute Verbindung nur durch eine sorgfältige und daher kostspielige Bearbeitung der Magnete und Polschuhe zu erreichen ist. Dazu kommt noch, daß die Verluste in den Polschuhen durch, die in sie eindringenden Befestigungsteile er-The invention relates to permanent magnet systems with pole pieces, in particular for ignition and luminous current generators. So far it has been customary to attach the pole pieces to the magnet by screws or the like. to fasten, or to attach the pole shoes to a housing enclosing the entire magnet system and to press them against the magnets. To fix the pole pieces in the housing a magneto-electric blasting machine has already been proposed, the housing van dovetails herumzugießen of the pole pieces. These known constructions all have the disadvantage that a good connection can only be achieved by careful and therefore expensive machining of the magnets and pole pieces. In addition, the losses in the pole pieces are caused by the fastening parts penetrating into them.

ao höht werden. Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß die Magnete um Ansätze der Polschuhe herumgegossen werden. Der Vorteil der Erfindung besteht darin, daß zur Befestigung der Magnete und Polschuhe bzw. zu ihrer Verbindung keine besonderen Befestigungsmittel notwendig sind und daß die Bearbeitung des harten Magnetwerkstoffes vermieden wird.
In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt. Es zeigenao be raised. According to the invention, these disadvantages are avoided in that the magnets are cast around approaches of the pole pieces. The advantage of the invention is that no special fastening means are required to fasten the magnets and pole shoes or to connect them and that machining of the hard magnetic material is avoided.
In the drawing, an embodiment of the subject matter of the invention is shown. Show it

Abb. 2 einen Schnitt nach der Linie 2-2 der Abb. i.Fig. 2 is a section along the line 2-2 of Fig. I.

Das dargestellte Magnetsystem besteht aus einer Anzahl aus Blechen zusammengesetzter Polschuhe ta, die mit gleichen Abständen voneinander im Kreis angeordnet sind. Zwischen den Polschuhen liegen Magnetstäbe b, die aus einem magnetisch hochwertigen Stahl, ζ. B. Aluminiumnickelstahl, bestehen. Die Polschuhe 'und die Magnetstäbe sind dadurch miteinander verbunden, daß um die Ansätze c der Polschuhe die Magnetstäbe herumgegossen sind. Die Ansätze sind im Ausführungsbeispiel schwalbenschwanzförmig. Der aus den Polschuhen und Magmetstäben gebildete Ring ist in an sich bekannter Weise in ein Gehäuse d aus Aluminium oder einem anderen nicht magnetischen Werkstoff ein- ^0 gegossen.The magnet system shown consists of a number of pole pieces ta composed of metal sheets, which are arranged in a circle at equal distances from one another. Magnetic rods b, which are made of high-quality magnetic steel, ζ, are located between the pole pieces. B. aluminum nickel steel exist. The pole pieces' and the magnetic bars are connected to one another in that the magnetic bars are cast around the lugs c of the pole pieces. In the exemplary embodiment, the approaches are dovetail-shaped. The ring formed from the pole shoes and is Magmetstäben in known manner in a housing d from aluminum or other non-magnetic material mono- ^ 0 poured.
