KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vielfach besteht das Bestreben, die Ankerrückwirkung von elektrischen Maschinen durch Kompensationswicklungen, die in Nuten der Polschuhe eingebettet werden, aufzuheben und gleichzeitig die zur Erregung nötige Energie möglichst zu vermindern.In many cases there is an effort to reduce the armature reaction of electrical machines Compensation windings, which are embedded in the grooves of the pole shoes, cancel and at the same time to reduce the energy necessary for arousal as much as possible.
Die gewöhnliche Bauart, die Polkerne samt den Polschuhen aus gestanzten Blechen zusammenzusetzen, hat den Nachteil, daß dieThe usual design of assembling the pole cores including the pole pieces from stamped sheet metal, has the disadvantage that the
ίο Polkerne nicht rund hergestellt werden können, und daß infolgedessen die Windungslänge der Polspulen erheblich länger wird als bei runden Spulen. Werden bei Verwendung von runden Polkernen die in achsialer Richtung längeren Polschuhe allein senkrecht zur Achse unterteilt, so ist die magnetische Leitfähigkeit in achsialer Richtung nicht gut. Es sind auch Polschuhe bekannt, die aus mehreren einzeln auf den Polkern aufgeschraubten massiven Zähnen bestehen, deren so gebildete Nuten eine Kompensationswicklung tragen.ίο pole cores cannot be made round, and that as a result the winding length of the pole coils is considerably longer than in the case of round coils. Will be in use of round pole cores only the pole shoes, which are longer in the axial direction, perpendicular to the Divided by the axis, the magnetic conductivity in the axial direction is not good. There are also known pole shoes that are made up of several individually screwed onto the pole core There are massive teeth whose grooves formed in this way carry a compensation winding.
Gemäß der Erfindung wird der Polschuh aus derartigen zahnförmigen, gezogenen oder ' gewalzten Eisenstäben, die etwa das in der Zeichnung dargestellte Profil haben, zusammengesetzt und diese aneinander befestigt, z. B. durch Zusammenschweißen oder Zusammenlöten, so daß der Polschuh ein selbständiges Ganze darstellt und als Ganzes am Polkern befestigt werden kann.According to the invention, the pole piece is made of such tooth-shaped, drawn or ' rolled iron bars, which have approximately the profile shown in the drawing, composed and these attached to each other, e.g. B. by welding or soldering together, so that the pole piece represents an independent whole and can be attached to the pole core as a whole.
