Description
Bei Asynchronmaschinen, deren Läufer mit Käfigwicklungen versehen sind, treten, insbesondere bei Schnelläufern, an den Auistrittssitellen der Wicklungsstäbe an dem Läu-S fereisen Funken auf. Derartige Maschinen sind infolgedessen für feuergefährliche Betriebe nicht verwendbar. Nach der Erfindung soll die Funkenbildung an den Läufern dadurch, vermieden werden, daß die Stäbe min-ο destans an einem Punkte durch Verlöten oder Verschweißen mit dem Läufereisen elektrisch leitend verbunden werden. Die elektrische Verbindung kann an irgendeinem Punkte des Läuferstabes vorgenommen werden, doch wird bei gleichzeitig mechanisch starrer Verbindung wie beim Verlöten die Verbindungsistelle am besten in der Mitte des Stabes gewählt, so daß dieser sich von da aus nach beiden Seiten gleichviel frei ausdehnen kann, wenn er im Betrieb erhitzt wird. Durch die elektrische Verbindung werden die Stäbe und das Läufereisen auf gleiches elektrisches Potential gebracht und damit elektrische Spannungsunterschiede vermieden, die zumIn the case of asynchronous machines, the rotors of which are provided with cage windings, occur at the Auistrittssitellen, especially in the case of high-speed rotors the winding bars on the runner free sparks. Such machines are consequently not usable for flammable establishments. According to the invention the formation of sparks on the rotors is to be avoided by keeping the rods min-ο destans electrically at one point by soldering or welding to the armature be conductively connected. The electrical connection can be made at any point of the Runner rod are made, but is at the same time mechanically rigid connection As with soldering, the connection point is best chosen in the middle of the rod, so that from there it is to both Sides can expand equally freely when heated during operation. By the electric Connection will be the bars and the runner iron on the same electrical Brought potential and thus avoided electrical voltage differences that lead to

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht. Diese zeigt einen . Läufer, der aus einem lamellierten Eisenpaket 2 besteht, das auf einer Welle 1 angeordnet ist. In dem Läufer liegt eine Käfigwicklung, die durch Stäbe 3 und Kurzschlußringe 4 gebildet wird. Nach ,der Erfindung sind die Stäbe an den Stellen a und b, an denen sie aus dem Eisen austreten, mit diesem verlötet. Am besten wird die Verlötung jedoch in der Mitte der Stäbe an dem Punkt c vorgenommen, wo das Lot durch ein in dem Eisen angeordnetes Loch 5 eingeführt werden kann. Die Stäbe brauchen jetzt nicht mehr dicht an den Nutenwänden anzuliegen, was fabrikatorisch sehr schwer zu erreichen ist. Die elektrische Verbindung zwischen den Stäben und den nicht mit ihnen verlöteten Lamellen ist über die Welle gesichert, auf die sämtliche Lamellen fest aufgepreßt -werden.An embodiment of the invention is illustrated in the drawing. This shows you. Runner, which consists of a laminated iron package 2, which is arranged on a shaft 1. A cage winding, which is formed by rods 3 and short-circuit rings 4, is located in the rotor. According to the invention, the bars are soldered to the points a and b where they emerge from the iron. However, the soldering is best done in the middle of the rods at point c , where the solder can be introduced through a hole 5 arranged in the iron. The bars no longer need to lie tightly against the groove walls, which is very difficult to achieve in terms of manufacturing. The electrical connection between the bars and the lamellas that are not soldered to them is secured by the shaft, onto which all the lamellas are firmly pressed.
