Description

Elektrische 1Kaschine mit einer in denselben Nuten wie die Hauptwicklung liegenden Dämpferwicklung. In dem Patent 443 752 .ist eine elektrische Maschine mit einer in denselben Nuten wie die Hauptwicklung liegenden Dämpferwicklung beschrieben. Die Dämpferwicklung ist so beschaffen, daß ihre Liter in den einzelnen Nuten oberhalb und unterhalb der Hauptleiter liegen und außerhalb der Nuten miteinander verbunden sind, so daß die so entstandenem, mit ihrer Windungsebene parallel oder nahezu parallel zur Nutenwandung liegenden Kurzschlußetromkreise die Nutenflüsse nahezu vollständig und streuungsfrei umfassen. Die vorliegende Erfindung gibt eine besonders vorteilhafte Ausführungsform für eine solche Dämpferwicklung. Sie besteht darin, daß die radial nach außen liegenden Seiten der Dämpferspule zum Teil. oder ganz in. den Nutenversc'hluß hineinverlegt werden.1 electric machine with one in the same slots as the main winding lying damper winding. In the 443,752 patent is an electric machine with a damper winding located in the same slots as the main winding. The damper winding is designed so that its liters in the individual grooves above and lie below the main conductor and connected to one another outside the grooves are, so that the so created, with their winding plane parallel or almost parallel the short-circuit current circuits lying to the wall of the groove, the groove flows almost completely and include free of scatter. The present invention gives a particularly advantageous one Embodiment for such a damper winding. It consists in that the radial outward sides of the damper coil in part. or completely in. the groove seal be relocated.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht. Diese zeigt einen Querschnitt durch die Nut n des wirksamen Eisens e und in dieser zwei; Leiter v und w mit der Isolation i. Ferner zeigt sie zwei in sich geschlossene Spulen c und k, deren radial nach außen liegende Teile c' und k' zum größten Teil in den Keile hineinragen. Der Keile ist zu diesem Zwecke radial nach innen ausgehöhlt. Er wird um allen Anforderungen an Festigkeit sowie elektrischer und magnetischer Leitfähigkeit zu entsprechen, vorteilhaft aus einem unmagnetischen, elektrisch schlecht leitenden Material, z. B. aus Nickelstahl oder Manganin, hergestellt. Wie ersichtlich, umfaßt die D,ämpferwicklung einen größeren Teil des Nutenstreufeldes als die in dem Hauptpatent dargestellte Ausführungsform. mit Nutenverschluß, wodurch ihre Wirksamkeit diesen Anordnungen gegenüber weiter erhöht wird.An embodiment of the invention is illustrated in the drawing. This shows a cross section through the groove n of the effective iron e and in this two; Conductors v and w with insulation i. It also shows two self-contained Coils c and k, whose radially outward parts c 'and k' for the most part protrude into the wedges. For this purpose, the wedge is hollowed out radially inward. It will meet all requirements for strength as well as electrical and magnetic Conductivity to match, advantageous from a non-magnetic, electrically poor conductive material, e.g. B. made of nickel steel or manganin. As can be seen the damper winding comprises a larger part of the slot stray field than that in Embodiment shown in the main patent. with groove lock, increasing their effectiveness compared to these arrangements is further increased.
