Der Hauptzweck dieser Erfindung ist die Vermeidung von Foucault'schen oder Inductionsströmen in den Ankerringen von dynamo-elektrischen Maschinen, aber dieselbe ist auch auf analoge Maschinen, sowie auch auf Elektromagnete und Inductionsspiralen im allgemeinen anwendbar.The main purpose of this invention is to avoid Foucault or induction currents in the anchor rings of dynamo-electric machines, but the same is also on analog machines, as well as electromagnets and induction spirals in general applicable.
Zu diesem Zwecke besteht der Magnetkern aus fein zertheiltem magnetischen Metall, vorzugsweise Eisen, dessen Theile von einander durch Firnifs oder anderes passendes Material isolirt sind. Dieses Gemisch wird entweder in dickflüssigem Zustande in passende Formen geprefst oder die gewünschte Form wird aus dem Gemisch geschnitten,' nachdem dasselbe sich gesetzt hat.For this purpose, the magnetic core consists of finely divided magnetic metal, preferably Iron, the parts of which are isolated from one another by firnifs or other suitable material. This mixture is either in viscous state pressed into suitable shapes or the desired shape is made from the Mixture cut 'after it has set.
Ein passendes Verfahren der Herstellung be-, steht darin, fein zertheiltes Eisen mit gepulvertem Harz oder Schellack zii mischen und das Gemisch unter gleichzeitiger Anwendung von Wärme zu comprimiren, so dafs das Harz oder der Schellack schmilzt und nach dem Erkalten sämmtliche Eisentheile von demselben ■ umhüllt sind. Zur Vermehrung derCohäsion ',;'/.■', kann man den genannten Bestandteilen noch ' Haare oder Fasern irgend welcher Art beifügen. Der Magnetkern kann in jeder belie-: bigen Form, entweder solid oder durchbrochen, .-: hergestellt werden.A suitable method of manufacture is it says to mix finely divided iron with powdered resin or shellac and to compress the mixture with the simultaneous application of heat, so that the resin or the shellac melts and, after cooling, all the iron parts of it are wrapped. To increase cohesion ',;' /. ■ ', you can add hair or fibers of any kind to the components mentioned. The magnetic core can be used in any: bigen form, either solid or openwork, .-: be made.
