Abstract

The electric machine (1) has runner sleeve shaft (3) with air inlet aperture (5) leading to air stream channel (4). The air stream channel comprises outward radial extension portion (6) within the end winding region of stator winding (7) at air outlet side. The fan blades (2) are arranged in the region of outward radial extension portion.

Description

Die Erfindung betrifft eine elektrische Maschine mit einer als Luftführungskanal ausgebildeten Läuferhohlwelle mit Lufteintrittsöffnungen und Luftaustrittsöffnungen im Bereich der Läuferhohlwelle.The invention relates to an electric machine having a rotor hollow shaft designed as an air duct with air inlet openings and air outlet openings in the region of the rotor hollow shaft.

Derartige elektrische Maschinen sind bekannt. Dabei wird die Verlustwärme des Läufers der elektrischen Maschine durch einen außen am Läufer angeordneten Sauglüfter, der Kühlluft durch die innen offene Läuferwelle zieht, abgeführt.Such electrical machines are known. In this case, the heat loss of the rotor of the electric machine is removed by a suction fan arranged on the outside of the rotor, which draws cooling air through the internally open rotor shaft.

Der Erfindung liegt daher die Aufgabe zugrunde, eine elektrische Maschine der oben genannten Art vorzuschlagen, die eine besonders effektive Verlustwärmeabfuhr aufweist.The invention is therefore based on the object to propose an electric machine of the type mentioned above, which has a particularly effective loss heat dissipation.

Die Aufgabe wird mit den Merkmalen nach Anspruch 1 gelöst.The object is achieved with the features of claim 1.

Dabei weist die elektrische Maschine eine nach außen radiale Erweiterung des Luftführungskanals innerhalb des Wickelkopfbereichs einer Ständerwicklung auf der Luftaustrittsseite der Maschine und Lüfterflügel auf, die im Erweiterungsbereich des Luftführungskanals angeordnet sind.In this case, the electrical machine has an outward radial extension of the air ducting within the winding head region of a stator winding on the air outlet side of the machine and fan blades, which are arranged in the extension region of the air duct.

Eine vorteilhafte Weiterbildung der elektrischen Maschine besteht, wenn gemäß Anspruch 2 die Lüfterflügel in der Art eines Radiallüfters angeordnet sind.An advantageous development of the electric machine is when according to claim 2, the fan blades are arranged in the manner of a radial fan.

Außerdem ist es vorteilhaft, wenn gemäß Anspruch 3 die elektrische Maschine ein Lagerschild aufweist, das innerhalb des Erweiterungsbereichs und der Lüfterflügel zur optimalen Luftführung dient.Moreover, it is advantageous if according to claim 3, the electric machine has a bearing plate, which serves within the extension area and the fan blades for optimum air flow.

Ein Ausführungsbeispiel der Erfindung wird im Folgenden anhand einer Zeichnung näher erläutert. Es zeigen:An embodiment of the invention will be explained in more detail below with reference to a drawing. Show it:

1 eine Längsschnittansicht der erfindungsgemäßen elektrischen Maschine, 1 a longitudinal sectional view of the electric machine according to the invention,

2 eine Seitenansicht der elektrischen Maschine nach 1 auf der Luftaustrittsseite und 2 a side view of the electric machine after 1 on the air outlet side and

Der Luftführungskanal 4 weist erfindungsgemäß nach außen eine radiale Erweiterung 6 innerhalb des Wickelkopfbereichs der Ständerwicklung 7 auf der Luftaustrittsseite der Maschine 1 auf sowie die Lüfterflügel 2, die im Bereich der Erweiterung 6 des Luftführungskanals 4 angeordnet sind.In 1 is the electric machine according to the invention 1 with fan blades 2 shown in longitudinal section. The electric machine 1 is in a known manner with an air duct 4 trained rotor hollow shaft 3 with air inlets 5 in the area of the rotor hollow shaft 3 educated. The air duct 4 according to the invention has a radial extension to the outside 6 within the winding head region of the stator winding 7 on the air outlet side of the machine 1 on as well as the fan blades 2 that are in the field of enlargement 6 of the air duct 4 are arranged.

Die elektrische Maschine 1 weist ein Lagerschild 9 auf, das innerhalb des Bereichs der Erweiterung 6 und der Lüfterflügel 2 zur optimalen Luftführung dient.The electric machine 1 has a bearing plate 9 on that within the scope of the extension 6 and the fan blade 2 serves for optimal air flow.

Durch die Erweiterung 6 ist eine Saughöhe geschaffen, die durch die hier angeordneten Lüfterflügel 2 eine Selbstlüftung bewirkt.By extension 6 is created a suction height, by the here arranged fan blades 2 causes a self-ventilation.

In 2 ist eine Ansicht der Luftaustrittsseite der elektrischen Maschine 1 mit den Luftaustrittsöffnungen 8 und dem durch diese hindurch sichtbaren Lüfterflügeln 2 geht zeigt.In 2 is a view of the air outlet side of the electric machine 1 with the air outlet openings 8th and the fan blades visible through them 2 goes shows.

Die Anordnung der Lüfterflügel 2 in der Art eines Radiallüfters ist in der Querschnittsansicht der elektrischen Maschine 1 gemäß 3 verdeutlicht.The arrangement of fan blades 2 in the manner of a radial fan is in the cross-sectional view of the electric machine 1 according to 3 clarified.
