Abstract
Scheibenförmiger Rotor (1) einer Elektroarbeitsmaschine, der magnetisch aktive Elemente (2) enthält, dadurch gekennzeichnet, dass der Rotor aus mehreren kreisförmigen metallischen Lamellen (3) besteht, die konzentrisch zum Kreismittelpunkt und parallel zueinander angeordnet sind, Taschen zur Aufnahme magnetisch aktiver Elemente enthalten und zur Sicherung gegen Verdrehen untereinander fest verbunden sind.Disc-shaped rotor (1) of an electrical work machine, the magnetically active elements (2), characterized in that the rotor consists of a plurality of circular metallic lamellae (3), which are arranged concentrically to the circle center and parallel to each other, containing pockets for receiving magnetically active elements and are firmly connected to each other to prevent rotation.
Description
Die Erfindung betrifft einen scheibenförmigen Rotor einer Elektroarbeitsmaschine, der magnetisch aktive Elemente enthält.The invention relates to a disk-shaped rotor of an electrical work machine containing magnetically active elements.
Rotoren derartiger Elektroarbeitsmaschinen werden wie in den Druckschriften
Es ist Aufgabe der vorliegenden Erfindung, einen kostengünstig und hoch-automatisiert herstellbaren scheibenförmigen Rotor einer Elektroarbeitsmaschine zur Aufnahme magnetisch aktiver Elemente und zur Reduzierung der Wirbelströme vorzuschlagen.It is an object of the present invention to provide a cost-effective and highly automated producible disc-shaped rotor of an electrical work machine for receiving magnetically active elements and to reduce the eddy currents.
Die Aufgabe wird durch einen scheibenförmigen Rotor gelöst, der aus einzelnen Lamellen (z. B. Blechen) besteht und somit vorzugsweise als Stanzteil hergestellt werden kann. Zwischen den Blechen befindet sich Kunststoff zum Fixieren und Verkleben, der zum einen die elektrische Isolierung der Bleche untereinander, zum anderen die mechanische Stabilität zur Aufnahme der im Betrieb auftretenden Querkräfte gewährleistet. Zusätzlich können in die einzelnen Lamellen Schitzungen zur Unterbrechung der Wirbelstrompfade eingebracht werden. Um die mechanische Stabilität nicht zu gefährden, sollen die Schlitzungen in jeweils zwei benachbarten Lamellen nicht an gleicher radialer und tangentialer Position sein.The object is achieved by a disk-shaped rotor which consists of individual laminations (for example metal sheets) and thus can preferably be produced as a stamped part. Between the sheets is plastic for fixing and gluing, on the one hand ensures the electrical insulation of the sheets with each other, on the other hand, the mechanical stability to absorb the transverse forces occurring during operation. In addition, in the individual lamellae can be introduced to interrupt the eddy current paths. In order not to endanger the mechanical stability, the slits in each two adjacent slats should not be in the same radial and tangential position.
Der Aufbau und die Bestandteile eines solchen Rotors sollen im Folgenden anhand von Figuren näher erläutert werden, wobeiThe structure and components of such a rotor will be explained in more detail below with reference to figures, wherein
