Description
Das Hauptpatent betrifft einen Kommutator für elektrische Maschinen mit axial verlaufenden Verbindungsfahnen zwischen den. Lamellen und den Wicklungsanschlüssen. Gemäß S der Erfindung des Hauptpatents ist zwecks besserer Abfuhr der am Kommutator erzeugten Wärme einerseits die für den Stromübergang benutzbare Kommutatoroberfläche so klein, daß sich pro Quadratzentimeter dieser Fläche mindestens 2 Watt Bürstenverluste ergeben, anderseits sind die Verbindungsfahnen zwecks Erhöhung der Wärmeabfuhr insbesondere durch Verlängerung in axialer Richtung zusätzlich vergrößert.The main patent relates to a commutator for electrical machines with axially extending Connecting flags between the. Lamellae and the winding connections. According to S of the invention of the main patent is for the purpose of better dissipation of those generated on the commutator Heat on the one hand the commutator surface that can be used for current transfer is so small that it is per square centimeter Surface area results in at least 2 watt brush losses, on the other hand are the connecting lugs for the purpose of increasing the heat dissipation, in particular by extending it in the axial direction additionally enlarged.
Gemäß der vorliegenden Erfindung ist der Kollektor in an sich bekannter Weise unterteilt, und die an den beiden Stirnseiten der Maschine angeordneten· Teilkollektoren sind mit ihren Lamellen durch Verbindungsfahnen, die gemäß dem Hauptpatent bemessen sind, an die Maschinenwicklung angeschlossen. An sich ist es namentlich bei Maschinen für hohe Stromstärken bekannt, den Kollektor zu teilen und die beiden Teile beiderseits des Läufers anzuordnen. Die Verwendung der Erfindung des Hauptpatents bei einer solchen Doppelkommutatormaschine ergibt jedoch eine besonders wirksame Wärmeabfuhr durch die vergrößerten Verbindungsfahnen. Diese Verbindungsfahnen saugen nunmehr die Wärme nicht nur von dem zugeordneten Kommutator ab, sondern auch von der Läuferwicklung, und zwar auf beiden Stirnseiten' der letzteren. Die Läuferwicklung kann also erheblich höher mit Strom belastet werden, ohne daß sich eine unzulässige Erwärmung einstellt.According to the present invention, the collector is subdivided in a manner known per se, and the partial collectors arranged on the two front sides of the machine with their lamellas by connecting lugs, which are dimensioned according to the main patent, connected to the machine winding. In itself it is especially true for machines for high Amperages known to divide the collector and the two parts on both sides of the rotor to arrange. The use of the invention of the main patent in such a double commutator machine however, results in a particularly effective heat dissipation through the enlarged connecting lugs. These connecting flags now suck the heat not only from the assigned commutator, but also from the rotor winding, on both sides of the latter. The rotor winding can therefore be considerably higher be charged with electricity without inadmissible heating.
Die Zeichnung veranschaulicht die Anordnung nach der Erfindung. 1 ist der Ständer einer Gleich- oder Wechselstromkommutatormaschine; 2 sind die beiden Kommutatorhälften, die über die Verbindungsfannen 3 je an eine Stirnseite der Läuferwicklung· angeschlossen sind. Die beiden Kommutatoren und die Verbindungsfahnen sind gemäß den eingangs geschilderten Bedingungen des Hauptpatents ausgebildet.The drawing illustrates the arrangement according to the invention. 1 is the stand a DC or AC commutator machine; 2 are the two commutator halves, which are each connected to an end face of the rotor winding via the connecting sockets 3 are. The two commutators and the connecting lugs are in accordance with the conditions described above Main patent trained.
