Description
Gemäß der Erfindung des Hauptpatentes 547 967, die einen Kommutator für elektrische Maschinen betrifft, ist einerseits die für den Stromübergang benutzbare Fläche des Kommutators so klein, daß sich pro Quadratzentimeter dieser Fläche mindestens 2 Watt Bürstenverluste ergeben; anderseits sind die Verbindungsfahnen zwischen dem Kommutator und der Wicklung zwecks Erhöhung der Wärmeabfuhr zusätzlich verlängert. Der Vorteil dieser neuen Kommutatorausbildung besteht in einer wesentlichen Verkleinerung des Kommutators,According to the invention of the main patent 547 967, which is a commutator for electrical Concerning machines, there is on the one hand the area of the commutator that can be used for current transfer so small that there is at least 2 watt brush losses per square centimeter of this area result; on the other hand are the connecting lugs between the commutator and the winding to increase the heat dissipation additionally extended. The advantage of this new commutator training consists of a significant reduction in the size of the commutator,
Gemäß der vorliegenden Erfindung ist zur weiteren Erhöhung der Kühlwirkung der Verbindungsfahnen (entweder zwischen der Wicklung und dem Kommutator oder zwischen zwei Kommutatorteilen) ein Ventilator vorgesehen, dessen Kühlluft zwischen den Verbindungsfahnen hindurchgeleitet ist. Zur Abfuhr der Kühlluft ist außerdem ein die Verbindungsfahnen außen umgebender Ringkanal vorgesehen. Derartige, die Verbindungsfahnen umgebende Ringkanäle sind bei Doppelkommutatoren bereits bekannt. Ihre VerwendungAccording to the present invention, the connecting lugs are used to further increase the cooling effect a fan is provided (either between the winding and the commutator or between two commutator parts), whose cooling air is passed between the connecting lugs. To discharge the Cooling air is also provided in an annular channel surrounding the connecting lugs on the outside. Such ring channels surrounding the connecting lugs are found in double commutators already known. Your use
25' für die Anordnung des Hauptpatentes erweist sich aber insofern als besonders zweckmäßig, weil dadurch die wärmeabsaugende Wirkung -der Verbindungsfahnen des Hauptpatentes noch besonders gefördert wird.25 'for the arrangement of the main patent but to the extent that it is particularly useful because it has the effect of absorbing heat -the connecting flags of the main patent is particularly promoted.
Die Zeichnung zeigt zwei Ausführungsbeispiele der Erfindung. In Abb. 1 sind 1 der Eisenkörper einer Kommutatormaschine, 2 die Lamellen des Kommutators, 3 die verlängerten Verbindungsfahnen zwischen den Kommutatorlamellen und der Wicklung. An die rechte Seite des Kommutators schließt sich nun ein Blechgehäuse 4 an, durch das mittels eines Ventilators 5 unter die Kommutatorlamellen Kühlluft geleitet wird, die dann zwischen den Verbindungsfahnen 3 nach außen strömt. 6 ist ein die Verbindungsfahnen umgebender Ringkanal für die Ableitung der Kühlluft nach unten.The drawing shows two exemplary embodiments of the invention. In Fig. 1, 1 are the iron bodies a commutator machine, 2 the lamellas of the commutator, 3 the extended connecting lugs between the commutator lamellas and the winding. A sheet metal housing is now attached to the right-hand side of the commutator 4, through the cooling air by means of a fan 5 under the commutator fins is passed, which then flows between the connecting lugs 3 to the outside. 6 is a the ring channel surrounding the connecting lugs for the discharge of the cooling air downwards.
Die Anordnung nach Abb. 2 betrifft einen Doppelkommutator mit Kommutatorteilen 7 und 8 und den verlängerten Verbindungsfahnen 9. 10 ist wieder der die Verbindungsfahnen umgebende Ringkanal, an dessen unterer Abführungsöffnung ein Saugventilator 11 angeschlossen ist. Die von außen angesaugte Luft umspült wieder zunächst die Innenseite der Kommutatorteile 7 und 8 und tritt dann zwischen den Verbindungsfahnen 9 nach außen.The arrangement according to Fig. 2 relates to a double commutator with commutator parts 7 and 8 and the extended connecting lugs 9. 10 is again the ring channel surrounding the connecting lugs, at its lower A suction fan 11 is connected to the discharge opening is. The air sucked in from the outside again first flows around the inside of the commutator parts 7 and 8 and then occurs between them the connecting lugs 9 to the outside.
