Description
Pol für elektrische Maschinen Die Pole elektrischer Maschinen bestehen bekanntlich in vielen Fällen aus lamelliertem Eisen, wobei sich die Lamellen in der Aehsrichtung der Maschine erstrecken können. Eine solche Anordnung ist in Fig. i der Zeichnung dargestellt, derzufolge beispielsweise die Hilfspole i in dieser Weise lamelliert sind.Pole for electrical machines The poles of electrical machines exist As is well known, in many cases made of lamellar iron, the lamellas being in the axis of the machine can extend. Such an arrangement is shown in Fig. i shown in the drawing, consequently, for example, the auxiliary poles i in this Way are laminated.
Die Pole elektrischer Maschinen können bekanntlich mit an der Polschaftwurzel vergrößertem Querschnitt ausgeführt werden, um d#e Lbergangsverluste am Joch zu verringern. Man hat zu diesem Zweck bekanntlich besonders geformte Platten zwischen Pol und Joch eingeschaltet oder die Querschnittsvergrößerung durch an die Pole angeschweißte Stäbe oder Bleche erreicht.As is well known, the poles of electrical machines can also be attached to the pole shaft root increased cross-section to reduce the transition losses at the yoke to decrease. For this purpose, it is known that specially shaped plates are between Pole and yoke switched on or the cross-sectional enlargement by being welded to the poles Bars or sheets reached.
Von der bei diesen Maßnahmen erforderlichen zusätzlichen Schweißarbeit u. dgl. kann man sich bei Verwendung axial verlaufender Lamellen frei machen, indem man erfindungsgemäß die an den Seiten des Poles liegenden Lamellen etwa rechtwinklig abbiegt.The additional welding work required for these measures and the like. You can make yourself free when using axially extending lamellae by according to the invention, the lamellae lying on the sides of the pole are approximately at right angles turns.
Ausführungsbeispiele für die Erfindung sind in Fig. 2 bis 5 dargestellt. Wie Fig. 2 erkennen läßt, sind die Lamellen i in bekannter Weise durch Punktschweißung 2 zusammengehalten, und die an den Seiten des Poles liegenden Lamellen sind bei 3 an der Polschaftwurzel abgebogen. Bei den Polen nach Fig. 3 und 4 sind die Lamellen ebenfalls durch Punktschweißung zu einem Block vereinigt, jedoch sind die Lamellen so abgebogen, daß sie Polschuhe 4. bilden. Man kann dabei die eben bleibenden mittleren Lamellen zurück-oder vorstehen lassen, um besondere Formen des Poles zu erreichen.Embodiments of the invention are shown in FIGS. As can be seen in FIG. 2, the lamellae i are spot welded in a known manner 2 held together, and the lamellae lying on the sides of the pole are at 3 bent at the pole shaft root. In the poles of Fig. 3 and 4 are the lamellae also united to form a block by spot welding, but the lamellas are bent so that they form pole pieces 4.. You can keep the middle ones Let the lamellas protrude or set back in order to achieve special shapes of the pole.
Werden die Pole nicht mit Polschuhen versehen, die als Auflagefläche für die Erregerwicklung dienen können, so kann beim Erfindungsgegenstand eine einwandfreie Halterung derselben dadurch erzielt werden, @daß an den Außenblechen abgebogene Lappen die Erregerspule U-förmig umklammern. Diese Ausführungsform zeigt Fig.5, derzufolge die außenliegenden Bleche 5 mit Einschnitten 6 versehen sind, so daß die Lappen 7 rechtwinklig nach außen hin abgebogen werden können.If the poles are not provided with pole pieces that serve as a contact surface can serve for the excitation winding, so can a flawless one in the subject matter of the invention Holding the same can be achieved @ that bent on the outer panels Clap the excitation coil in a U-shape. This embodiment is shown in Fig. 5, consequently the outer metal sheets 5 are provided with incisions 6 so that the tabs 7 can be bent outwards at right angles.
