Wechsel stromgenerator· mit Datiermagn eti au f er AC generator · with date magnet on top
Die Erfindung hat einen Wechselstromgenerator zum Gegenstand, mit einem fliegend gelagerten Dauermagnetläufer und mit einem den Läufer und den Stator der Maschine umgebenden, einseitig geschlossenen Gehäuse y an dessen Innenwand der Stator mit seiner Wicklung befestigt ist.The object of the invention is an alternator with a cantilevered permanent magnet rotor and with a housing y which is closed on one side and which surrounds the rotor and the stator of the machine, on the inner wall of which the stator is fastened with its winding.
Derartige Generatoren, bei denen auf der Antriebsseite kein Luftzutritt stattfindet, bedürfen einer besonderen Kühlung, wenn ihre Leistung voll ausgenützt werden soll.Generators of this type in which there is no air admission on the drive side takes place, require special cooling if their performance is to be fully utilized.
Zu diesem Zweck ist gemäß der Erfindung auf der der Antriebsseite
abgewandten Gehäuseseite eine Öffnung für einen in axialer Richtung
in das Gehäuse eintretenden Kühlluftstrom vorgs^hen, der am
Mnrnotläufer entlang und am Stator uns seiner Wicklimg vorbei
durch radiale Öffnungen im Gehäusernaritel aiis dem Gehäuse austritt.For this purpose, according to the invention, on the housing side facing away from the drive side, an opening is provided for a cooling air flow entering the housing in the axial direction, which flows along the emergency rotor and past the stator and its winding
exits through radial openings in the housing casing.

Durch einen am Magnetläufer befestigten Sauglüfter kann dabei bewirkt werden, daß belüftete Generatoren bei gleicher Erwärmung die doppelte Leistung abgeben wie unbelüf.tete Generatoren.A suction fan attached to the magnetic rotor can do this the effect that ventilated generators deliver twice the power as unbelüf.tete generators with the same heating.
Bei Magnetläufern, deren Teile (Magnete, Kraftlinienleitstücke, Nabe) von einem nichtmagnetischen Werkstoff umspritzt sind, kann der Lüfter ohne wirklichen Aufwand durch aus dem Material der Spritzmasse herausgeformte Lüfterflügel hergestellt werden.In the case of magnetic rotors whose parts (magnets, force line guide pieces, Hub) are encapsulated by a non-magnetic material, the fan can be made of the material of the Injection molding molded fan blades are produced.
In der Zeichnung ist ein erfindungsgemäßer Generator dargestellt und zwar inIn the drawing, a generator according to the invention is shown in FIG
Pig. 1 ein Längsschnitt durch Gehäuse, Stator und Läufer und inPig. 1 shows a longitudinal section through the housing, stator and rotor and in
Fig. 2 der Magnetläufer des Generators nach Fig. 1 in der Ansicht von vorne.FIG. 2 shows the magnetic rotor of the generator according to FIG. 1 in a view from the front.
Gemäß Fig. 1 ist ein Magnetgenerator in eine auf seiner Antriebsseite offenes zylindrisches Gehäuse 10 eingebaut, an dessen Innenwand ein Stator 11 mit einer Wicklung 12 befestigt ist. Ein auf einer Antriebswelle 13 fliegend gelagerter Magnetläufer ragt in das Gehäuse 10 hinein. Er besteht aus einem Eisenkern 14, an den zwölf um Je 30° gegeneinander vernetzte Dauermagnete 15 angesetzt sind. Der Eisenkern 14 und die Magnete 15 sind von einer Aluminiumvergußmasse 16 umgeben, durch die sie zusammengehalten werden und die'auf der dem Antrieb abgewandten Seite in Lüfterflügel 16' ausläuft. Durch die Lüfterflügel 16' wird Kühlluft durch eine zentrale öffnung 17' in der der Antriebsseite abgewandten Gehäuseabdeckung 17 angesaugt. Sie tritt in axialer Richtung entlang den strichpunktierten Linien in das Gehäuse ein, strömt am Magnet!aufer entlang und am Stator 11 mit seiner Wicklung 12 vorbei und tritt durch radiale öffnungen 18 im Gehäusemantel wieder aus dem Gehäuse 10 aus.According to FIG. 1, a magnetic generator is installed in a cylindrical housing 10, which is open on its drive side, on its inner wall a stator 11 with a winding 12 is attached. A magnetic rotor mounted overhung on a drive shaft 13 protrudes into the housing 10 into it. It consists of an iron core 14 to which twelve permanent magnets 15 are attached, each of which is cross-linked by 30 ° are. The iron core 14 and the magnets 15 are made of an aluminum casting compound 16, by which they are held together and which 'runs out into fan blades 16' on the side facing away from the drive. By the fan blades 16 'cooling air is through a central Opening 17 'in the housing cover facing away from the drive side 17 sucked in. It occurs in the axial direction along the dash-dotted line Lines enter the housing and flow along the magnet! and past the stator 11 with its winding 12 and emerges again from the housing 10 through radial openings 18 in the housing jacket the end.

Wie aus Fig. 2 ersichtlich, ist, ißt der Lüfter bei dem gezeichneten Ausführungsbeispiel des Erfindungsgegenstandes mit sieben Flügeln 16' versehen.As can be seen from Fig. 2, the fan eats in the one drawn Embodiment of the subject invention provided with seven wings 16 '.
Wie bereits eingangs erwähnt wurde, können derartige, mit Lüfter versehene Generatoren die doppelte Leistung abgeben wie unbelüftete Generatoren.As already mentioned at the beginning, those with a fan Provided generators deliver twice the power as non-ventilated generators.
