Description

Die Erfindung betrifft eine elektrische Maschine, insbesondere einen elektrischen Erzeuger, mit Außenläufer.The invention relates to an electrical machine, in particular one electrical generator, with external rotor.

Bei elektrischen Maschinen erfolgt die Stromzuführung bzw. die Stromabnahme vielfach über Stromwender. Diese Stromwender haben zylindrische Gestalt. Auf ihrer zylindrischen Außenfläche schleifen die an besonderen Halterungen angebrachten Bürsten. Bei diesen elektrischen Maschinen nimmt die Bürstenhaltung verhältnismäßig viel Platz in Anspruch, der bei Aggregaten, welchen nur geringer Raum zur Verfügung steht, in unangenehmer Weise ins Gewicht fällt.In the case of electrical machines, power is supplied or drawn often via commutators. These commutators have a cylindrical shape. On your The brushes attached to special holders grind the cylindrical outer surface. With these electrical machines, the brush position takes a relatively large amount Space that is required for units with only a small amount of space available is uncomfortably significant.

Gemäß der Erfindung werden die vorerwähnten Mängel behoben, wenn man die zylindrischen Kommutatoren als Mantelkommutatoren ausbildet in der Weise, daß die Bürsten auf der Innenseite des Mantelkommutators schleifen. Eine solche Ausgestaltung elektrischer Maschinen ist von besonderer Bedeutung für elektrische Erzeuger mit Außenläufer. Bei diesen dient dann der stark peripher angeordnete Kommutator mitsamt dem Gehäuse und dem Lagerschild als Schwungmasse.According to the invention, the aforementioned shortcomings are eliminated if one trains the cylindrical commutators as jacket commutators in such a way that grind the brushes on the inside of the jacket commutator. Such a design electrical machinery is of particular importance to electrical producers having Outrunner. In this case, the commutator, which is arranged strongly on the periphery, is used along with it the housing and the end shield as a flywheel.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.

Die elektrische Maschine I besteht aus dem Außenläufer 2 und dem feststehenden Innenteil 3. Der Außenläufer wird gebildet durch die Läufer wicklungen 4, das Gehäuse 5, den Mantelkommutator 6 und die Lagerschilde 7 und 8, die, wie bei 9 und Io angedeutet, im Bereich der Kugellager doppelwandig ausgeführt sind. Die Kugellager II sind von den Schwungringen I2 eingeschlossen. Durch die feststehende Welle I3 sind die Stromanschlüsse I4 für den in der Mitte vorgesehenen Ständer I5 geführt, desgleichen die Stromanschlüsse Io für die Bürsten I7, die auf der Innenseite des Mantelkommutators 6 schleifen. Die außerordentlich kleine Bürstenbrücke I8 ist ebenfalls auf der Welle I5 befestigt und nimmt praktisch nur den Raum in Anspruch, der innerhalb des Kommutators zu ihrer Verfügung steht. Wie man aus der Zeichnung ersieht, ist der dargestellte Erzeuger als geschlossene Maschine ausgeführt. Der Stumpf I9 der Welle ist durch die dicke Lagerkappe 2o vollkommen abgedeckt. Es ist natürlich auch möglich, den neuen Stromerzeuger offen auszuführen. In diesem Falle ergibt das außen rotierende Gehäuse eine besonders gute Belüftung der ganzen elektrischen Maschine.The electrical machine I consists of the external rotor 2 and the stationary one Inner part 3. The outer rotor is formed by the rotor windings 4, the housing 5, the jacket commutator 6 and the end shields 7 and 8, which, as indicated at 9 and Io, are double-walled in the area of the ball bearings. The ball bearings II are from the flywheels I2 included. The power connections are through the stationary shaft I3 I4 for the stand I5 in the middle, as well as the power connections Io for the brushes I7, which grind on the inside of the jacket commutator 6. The extremely small brush bridge I8 is also attached to the shaft I5 and practically only takes up the space that is inside the commutator to their Available. As can be seen from the drawing, the represented producer is designed as a closed machine. The stump I9 of the shaft is through the thick Bearing cap 2o completely covered. It is of course also possible to use the new power generator to be carried out openly. In this case, the exterior rotating housing gives a special one good ventilation of the whole electrical machine.
