Abstract

The rotor comprises a shaft on which laminated pole pieces (2) are assembled, on suitable keys. In the interpolar space the permanent magnets (4) are located. The axis of magnetisation is tangential to the rotational axis of the rotor. The magnets are held in position by an axial strip (5) with a T-head at each end. The strip bears against a lip (3) on each pole and thus supports the magnet against radial forces. The method of construction eliminates the need for attaching support brackets to the poles. Thus both manufacturing time and space in the machine are saved, the latter allowing greater output from a given rotor size. There is also a reduction in the number of components.

Beschreibung description

Die Erfindung bezieht sich auf einen rotierenden Induktor für elektrische Maschinen, insbesondere auf einen rotierenden Induktor, dessen Magnetachsen tangential zur Rotationsachse gerichtet sind.The invention relates to a rotating inductor for electrical Machines, especially on a rotating inductor, whose magnetic axes are tangential are directed to the axis of rotation.

Bekannt ist ein rotierender Induktor für elektrische Maschinen mit Dauermagneten, deren Magnetachsen tangential zur Rotationsachse gerichtet sind, bestehend aus einer Welle mit daran befestigten Polschuhen, die den durch zwischen denselben anyebrachte Dauermagnete erzeugten Magnetstrom in Radialrichtung lenken. Die Dauermagnete sind mit den Polschuhen zwischen zwei Scheiben aus nichtmagnetischem Werkstoff durch Stiftschrauben axial eingespannt, die durch Bohrungen in den Polschuhen geführt sind. In Radialrichtung sind die Dauermagnete durch Paßfedern aus nichtmagnetischem Werkstoff in Nuten im Oberteil der Seitenflächen der Polschuhe gesichert.A rotating inductor for electrical machines is known Permanent magnets, the magnet axes of which are directed tangentially to the axis of rotation, consisting of a shaft with attached pole pieces that pass through between direct the same magnetic current generated by any permanent magnet in the radial direction. The permanent magnets are made of non-magnetic with the pole pieces between two disks The material is clamped axially by stud bolts, which are inserted through holes in the pole pieces are led. In the radial direction, the permanent magnets are made of non-magnetic through feather keys Material secured in grooves in the upper part of the side surfaces of the pole shoes.

Nachteil dieser Konstruktion sind: das Vorhandensein von Bohrungen für die Stiftschrauben in den Polschuhen, das Vorhandensein von die Konstruktion erschwerenden Scheiben, sowie die Unmöglichkeit eines geringeren Abstands zwischen den Polen im Vergleich zur Magnetlange.Disadvantages of this construction are: the presence of holes for the stud bolts in the pole pieces, the presence of the construction aggravating discs, as well as the impossibility of a smaller distance between the poles compared to the magnet length.

Aufgabe der Erfindung ist es, die Nachteile der bekannten Konstruktion zu vermeiden und einen rotierenden Induktor für eine elektrische Maschine mit reduzierter Masse, reduziertem Volumen und reduziertem Trägheitsmoment zu schaffen, wobei die Polfläche bei vervollkommneter Technologie vergrößert werden soll.The object of the invention is to overcome the disadvantages of the known construction to avoid and use a rotating inductor for an electric machine with reduced To create mass, reduced volume and reduced moment of inertia, the Pole surface is to be enlarged with perfected technology.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die äußeren Enden der Polschuhe mit Kanten versehen sind, unter denen an den Polschuhen eingespannte doppel-T-förmige Spannbügel angebracht sind, von denen ein jeder die Pakete zweier Nachbarpolschuhe gleichzeitig einspannt, und daß in Radialrichtung die im Raum zwischen dem Bügel, der Welle und den Polschuhen angebrachten Dauermagnete befestigt sind.This object is achieved according to the invention in that the outer Ends of the pole pieces are provided with edges, under which clamped on the pole pieces Double-T-shaped clamps are attached, each of which holds the packages of two At the same time clamps neighboring pole pieces, and that in the radial direction in the space between Permanent magnets attached to the bracket, the shaft and the pole pieces are attached.

Vorteile des erfindungsgemäßen rotierenden Induktors für eine elektrische Maschine sind: das Fehlen von Stiftschrauben und Bohrungen für dieselben in den Polschuhpaketen, das Fehlen nichtmagnetischer Seitenscheiben, die Möglichkeit zur Vergrößerung der Polfläche zu Lasten der Polschuhkanten und die vereinfachte Technologie infolge des Wegfallens einer wesentlichen Anzahl konstruktiver Bauteile.Advantages of the rotating inductor according to the invention for an electrical Machine are: the lack of studs and holes for the same in the Pole shoe packs, the lack of non-magnetic side windows, the possibility of Enlargement of the pole area at the expense of the pole piece edges and the simplified technology as a result of the elimination of a significant number of structural components.

Eine Ausführungsbeispiel der Erfindung ist in den beiliegenden Zeichnungen gezeigt. Es zeigen: Fig. 1 den Querschnitt eines rotierenden Induktors für eine elektrische Maschine und Fig. 2 die Seitenansicht eines rotierenden Induktors für eine elektrische Maschine.An embodiment of the invention is in the accompanying drawings shown. 1 shows the cross section of a rotating inductor for a electrical machine and FIG. 2 shows the side view of a rotating inductor for an electric machine.

Wie aus den Figuren ersichtlich, sind auf der Welle 1 die aus Polblechen bestehenden Polschuhe 2 befestigt, zwischen denen Dauermagnete 4 mit zur Rotationsachse tangential gerichteten Magnetachsen liegen. Die äußeren Enden der Polschuhe 2 sind mit Auflagen oder Kanten 3 versehen, unter denen an den Polschuhen 2 eingespannte I-förmige Spannbügel 5 angebracht sind, von denen ein jeder die Pakete zweier benachbarter Polschuhe 2 gleichzeitig einspannt. In Radialrichtung sind die im Raum zwischein dem Bügel 5, der Welle 1 und den Polschuhen 2 angebrachten Dauermagnete 4 befestigt.As can be seen from the figures, the shaft 1 is made of pole sheets existing pole shoes 2 attached, between which permanent magnets 4 with the axis of rotation tangentially directed magnet axes lie. The outer ends of the pole pieces 2 are provided with supports or edges 3, under which clamped on the pole pieces 2 I-shaped clamps 5 are attached, each of which the packages of two adjacent Pole shoes 2 clamped at the same time. In the radial direction they are in between the bracket 5, the shaft 1 and the pole pieces 2 attached permanent magnets 4 attached.
