ROTOR EINER ELEKTRISCHEN MASCHINEROTOR OF AN ELECTRIC MACHINE

Die Erfindung bezieht sich auf einen Rotor einer elektrischen Maschine der im Oberbegriff des Patentanspruchs beschriebenen, aus den BG-A 24 523 und -29 845 bekannten Art.The invention relates to a rotor of an electrical machine of the type described in the preamble of the claim, from BG-A 24 523 and -29 845 known Art.

Bei den bekannten Rotoren sind die inneren Enden der Polendstücke schwalbenschwanzförmig ausgebildet und mittels einer durch Gießen hergestellten Buchse aus nichtmagnetischem Material unbeweglich miteinander verbunden. Die äußeren Enden der Polendstücke sind mit Borden versehen, unterhalb denen zu den Polendstücken gespannte Bügel angeordnet sind.In the known rotors, the inner ends are the pole end pieces Dovetail-shaped and made of non-magnetic by means of a socket made by casting Material immovably connected to one another. The outer ends of the pole end pieces are provided with ribs, underneath which clamps are arranged to the pole end pieces.

Bei der bekannten Konstruktion wird durch die schwalbenschwanzförmige oder ähnliche Form der inneren Enden der Polendstücke und durch die Borde an ihren äußeren Enden die radiale Abmessung des Magneten vermindert, so daß der nützliche Magnetfluß der Maschine reduziert wird. Infolge der Schwalbenschwanzform der Enden und durch die Welle der Maschine sind auch die magnetischen Streuflüsse verhältnismäßig hoch.In the known construction is through the dovetail-shaped or similar shape of the inner ends of the pole end pieces and the rims at their outer ends Radial dimension of the magnet is reduced so that the useful magnetic flux of the machine is reduced. As a result of Dovetail shape of the ends and through the shaft of the machine the magnetic leakage fluxes are also proportionate high.

Der Erfindung liegt die Aufgabe zugrunde, einen Rotor für eine elektrische Maschine mit tangential ausgerichteten Permanentmagneten und zwischen ihnen angeordneten Polendstükken anzugeben, der einen erhöhten nützlichen Magnetfluß und einen verminderten magnetischen Streufluß durch die Welle der Maschine aufweist.The invention is based on the object of a rotor for an electrical machine with tangentially aligned permanent magnets and to indicate pole end pieces arranged between them which have an increased useful magnetic flux and has reduced magnetic flux leakage through the shaft of the machine.

Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch genannten Maßnahmen gelöst.According to the invention, this object is achieved by the measures mentioned in the patent claim.

Bei dem erfindungsgemäßen Rotor ist die radiale Abmessung des Magneten vergrößert und dadurch der nützliche Magnet-In the rotor according to the invention, the radial dimension of the magnet is increased and thus the useful magnet

fluß der Maschine gesteigert. Die inneren Enden der Polendstücke können in einer Form ausgebildet werden, die minimale magnetische Streuflüsse durch die Welle der Maschine gewährleistet .machine flow increased. The inner ends of the pole tails can be designed in a shape that ensures minimal magnetic leakage flux through the shaft of the machine .

Ein Ausführungsbeispiel des erfindungsgemäßen Rotors wird anhand der Zeichnung erläutert. Es zeigen:An embodiment of the rotor according to the invention is explained with reference to the drawing. Show it:

Fig. 1 den Querschnitt undFig. 1 shows the cross section and

Fig. 2 den Längsschnitt eines Rotors.2 shows the longitudinal section of a rotor.

Gemäß Fig. 1 und 2 sind in in den Seitenflächen der Polendstücke 1 ausgebildete Kanäle Keile 2 eingeschlagen, die länger als die Polendstücke 1 sind. Nichtmagnetische Verbindungselemente 3 verbinden mechanisch die Enden der Keile 2 miteinander und mit der Welle 4 der Maschine.According to FIGS. 1 and 2, channels 2 formed in the side surfaces of the pole end pieces 1 are driven in, which are longer than the pole tails are 1. Non-magnetic connecting elements 3 mechanically connect the ends of the wedges 2 with each other and with the shaft 4 of the machine.

Weil in in zwei oder mehr Längsflächen der Endstücke 1 vorgesehene Kanäle Keile 2 eingeschlagen sind, deren Länge größer ist als die der Endstücke 1, und weil die Enden dieser Keile 2 durch das nichtmagnetische Verbindungsgelement 3 untereinander und mit der Welle 4 der Maschine mechanisch verbunden sind, werden die radialen Abmessungen der Magneten vergrößert. Hierdurch wird der nützliche Magnetfluß gesteigert und die grundlegenden Betriebskennzahlen der Maschine werden verbessert. Außerdem sind die magnetischen Streuflüsse durch die Welle der Maschine vermindert, wodurch die Nutzbarkeit des Magneten gesteigert ist.Because in two or more longitudinal surfaces of the end pieces 1 provided Channels wedges 2 are driven in, the length of which is greater than that of the end pieces 1, and because the ends of these Wedges 2 through the non-magnetic connecting element 3 are mechanically connected to each other and to the shaft 4 of the machine, the radial dimensions of the magnets enlarged. This increases the useful magnetic flux and increases the basic operating metrics of the machine are improved. In addition, the magnetic leakage flux through the shaft of the machine is reduced, whereby the usability of the magnet is increased.
