Abstract

In the case of an electrical machine in the form of an external rotor with a fixed-position winding, it is provided in order to increase the power or efficiency that the winding (1) projects without iron or with iron into an annular gap in the rotor (3), which annular gap has a magnet system (2) at least on the radially outer wall. <IMAGE>

Description

Die Erfindung betrifft eine elektrische Maschine in Form ei-The invention relates to an electrical machine in the form of a

nes Außenläufers mit ortsfester Wicklung.external rotor with stationary winding.

Eine Maschine dieser Art ist beispielsweise für den Antrieb eines Hochgeschwindigkeits-Schwungringes ausgeführt (Archiv für Elektrotechnik 59 /1977/ S. 241, Bild 15). Dabei befindet sich ein Erregermagnetsystem auf der Innenseite eines zylindrischen Läufers, der um eine ortsfeste Statorwicklung rotiert, die von einem Stator aus Kunststoff getragen wird.A machine of this type is for example for driving a High-speed flywheel (Archive for Electrical Engineering 59/1977 / P. 241, Fig. 15). There is an exciter magnet system on the inside a cylindrical rotor that rotates around a stationary stator winding that is driven by a stator made of plastic is carried.

Der Erfindung liegt die Aufgabe zugrunde, einen Außenläufer der eingangs genannten Art so auszubilden, daß bei gleichem Maschinenvolumen eine wesentlich höhere Leistung mit geringem konstruktiven Aufwand erzielt wird.The invention is based on the object of providing an external rotor of the initially specified to train mentioned type so that with the same machine volume a substantial higher performance is achieved with little construction effort.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Hauptanspruchs angegebenen Merkmale gelöst.According to the invention, this object is achieved by the characterizing features of the main claim specified features solved.

Die weitere Ausgestaltung des Erfindungsgegenstandes geht aus den Unteransprüchen hervor, Die mit der Erfindung erzielten Vorteile bestehen darin, daß durch die Anordnung der Wicklung in einem Ringspalt des Läufers die Mittelwertinduktion gegenüber bekannten Außenläufern nahezu verdoppelt wird.The further development of the subject matter of the invention is based on Subclaims emerge, the advantages achieved with the invention are that by arranging the winding in an annular gap of the rotor, the mean value induction compared to known external rotors is almost doubled.

Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden nachstehend näher beschrieben.Two embodiments of the invention are shown in the drawing and are described in more detail below.

Es zeigen: Fig. 1 einen axialen Schnitt einer ersten Ausführungsform der elektrischen Maschine (Prinzipdarstellung), Fig. 2 einen radialen Schnitt der Maschine nach Fig. 1, Fig. 3 einen axialen Schnitt einer zweiten Ausführungsform der elektrischen Maschine (Prinzipdarstellung), Fig. 4 einen radialen Schnitt der Maschine nacn Fig. 2, und Fig. 5 eine graphische Darstellung, die die Mittelwertinduktion der Maschine nach der Fig. 1 und 2 bzw. 3 und 4 im Vergleich mit Mittelwertinduktionen von bekannten elektrischen Maschinen zeigt.1 shows an axial section of a first embodiment of the electrical machine (schematic diagram), FIG. 2 shows a radial section of the Machine according to Fig. 1, Fig. 3 is an axial section of a second Embodiment of the electrical machine (schematic diagram), FIG. 4 a radial one Section of the machine according to FIG. 2, and FIG. 5 is a diagram showing the Average value induction of the machine according to FIGS. 1 and 2 or 3 and 4 in comparison shows with mean value inductions of known electrical machines.

Die Fig. 1 und 2 zeigen eine Maschine, bei der eine ortsfeste Wicklung 1 in einen Ringspalt des Läufers 3 hineinragt, bei dem ein Magnetsystem 2, das einen geschlossenen Zylinder bildet, an der radial äußeren Wand des Ringspaltes angeordnet ist.1 and 2 show a machine in which a stationary winding 1 protrudes into an annular gap of the rotor 3, in which a magnet system 2, the one forms closed cylinder, arranged on the radially outer wall of the annular gap is.

Bei der in den Fig. 3 und 4 dargestellten Ausführungsform der Maschine, die prinzipiell genauso offenbart ist wie die Ausführungsform nach den Fig. 1 und 2, ist ein weiteres Magnetsystem auf der radial inneren Wand des Ringspaltes vorgesehen.In the embodiment of the machine shown in FIGS. 3 and 4, which is disclosed in principle in exactly the same way as the embodiment according to FIGS. 1 and 2, another magnet system is provided on the radially inner wall of the annular gap.

Fig. 5 zeigt über eine Polbreite aufgetragen die auf die Remanenzinduktion bezogene Mittelwertinduktion BZM/BR. Dabei stellen die Verläufe a - d folgendes dar: a magnetischer RUckschluß in Luft (Stand der Technik), b magnetischer RUckschluß einseitig in Eisen (Stand der Technik), c magnetischer Rückschluß zweiseitig in Eisen bei einseitiger Anordnung des Magnetsystems (Fig. 1 und 2), d magnetischer Rückschluß zweiseitig in Eisen bei zweiseitiger Anordnung des Magnetsystems (Fig. 3 und 4).5 shows the remanent induction plotted over a pole width related mean value induction BZM / BR. The courses a - d represent the following represents: a magnetic yoke in air (state of the art), b magnetic yoke on one side in iron (state of the art), c magnetic return on both sides in Iron with one-sided arrangement of the magnet system (Fig. 1 and 2), d magnetic return on both sides in iron with two-sided arrangement of the magnet system (Figures 3 and 4).
