KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung bezieht sich auf eine Neuerung an derjenigen Art von Wechselstrommaschinen, bei welcher der unbewegliche Theil des Magnetfeldes aus einem Eisenrahmen mit nach innen ragenden, mit je einer Inductionsspule umwickelten Polvorsprüngen besteht. Die Neuerung bezweckt, die Inductionswirkungen auf die Magnetisirungsspulen zu vermeiden, obwohl letztere in der unmittelbaren Nähe der Inductionsspulen angebracht sind.The present invention relates to an innovation of that type of alternating current machine, at which the immobile part of the magnetic field comes from an iron frame with inwardly protruding pole projections, each wound with an induction coil. The aim of the innovation is to avoid the induction effects on the magnetizing coils, although the latter are placed in the immediate vicinity of the induction coils.
In der Zeichnung ist eine der Erfindung gemäfs eingerichtete Wechselstrommaschine in Endansicht dargestellt.In the drawing, an alternating current machine set up according to the invention is shown in FIG End view shown.
A ist der Eisenrahmen. welcher entweder ganz aus Lamellen oder zum Theil aus Lamellen und zum Theil massiv hergestellt ist. nn s s sind die in diesem Rahmen angebrachten, nach innen vorragenden Pole, von denen jeder mit einer Inductionsspule J umwickelt ist. B ist der im Rahmen A rotirende lamellirte Eisenanker. Derselbe trägt keine Bewickelung und ist mit Vorsprüngen b versehen, deren Anzahl zweckmäfsig halb so grofs ist wie die der Pole des Rahmens. A is the iron frame. which is made either entirely from lamellas or partly from lamellas and partly solid. nn ss are the inwardly protruding poles attached to this frame, each of which is wrapped with an induction coil J. B is the laminated iron anchor rotating in frame A. It has no wrapping and is provided with projections b , the number of which is expediently half as great as that of the poles of the frame.
Die Neuerung besteht darin, dafs die Pole des Rahmens A, wie aus der Figur ersichtlich, paarweise mit einer gemeinsamen Magnetisirungsspule M derart umwickelt sind, dafs zwei neben einander liegenden, von derselben Magnetisirungsspule umwickelten Polen nördliche Polarität, den beiden darauf folgenden Polen südliche Polarität u. s. w. ertheilt wird, wenn ein Gleichstrom durch die Spulen M fliefst. Haben die Vorsprünge des Kernes B eine genügende Breite (zweckmäfsig die doppelte Breite der stillstehenden Pole), so erfährt bei der Umdrehung des Ankers der Magnetismus der zwei neben einander liegenden Polen gleicher Polarität zugehörigen Magnetisirungsspule keine Aenderung, während dagegen der Magnetismus der diesen Polen zugehörigen Inductionsspulen schnellen Wechseln unterworfen ist. Indem der Magnetismus in den stillstehenden Polen zwischen Null und einem Maximum wechselt, entsteht ein Wechsel des Magnetismus auch in dem rotirenden Theil. Im Rahmen ist der Magnetismus theils constant, theils wechselnd; in den Theilen, welche zwischen einem Nordpol und einem Südpol liegen, ist der Magnetismus constant, weshalb diese Theile auch massiv hergestellt werden können.The innovation consists in the fact that the poles of the frame A, as can be seen from the figure, are wrapped in pairs with a common magnetizing coil M in such a way that two adjacent poles wrapped by the same magnetizing coil have north polarity, the two following poles south polarity, and so on is given when a direct current flows through the coils M. If the projections of the core B have a sufficient width (expediently twice the width of the stationary poles), the magnetism of the magnetizing coils belonging to two adjacent poles of the same polarity does not change during the rotation of the armature, whereas the magnetism of the induction coils belonging to these poles does not change is subject to rapid changes. As the magnetism in the stationary poles alternates between zero and a maximum, a change in magnetism also arises in the rotating part. In the frame the magnetism is partly constant, partly changing; in the parts which lie between a north pole and a south pole the magnetism is constant, which is why these parts can also be made solid.
