Die
Erfindung betrifft Läufervorrichtung

Maschinen mit einer zylindrischen Läuferpaketeinrichtung (
Stand der TechnikState of the art
Läufer von
Synchronmotoren, bei denen Permanentmagnete am Außenumfang
des Läuferpaketes
angeordnet sind, benötigen
zur radialen Fixierung der Permanentmagnete eine Bandage, die um den
Läufer
gewickelt ist. Gemäß dem Stand
der Technik wird dazu ein Faserverbundmaterial benutzt, das mit
einer Vorspannung auf die Magnete aufgewickelt und fixiert werden
muss. Eine entsprechende Lösung
ist in der Patentschrift
Die
Temperatur des Läufers
kann durch die unterschiedlichen Ausdehnungskoeffizienten von Läuferpaket
und Bandage einen erheblichen Einfluss haben, was in der Erfindung
Das
Verkleben der Enden des Bandes für
die Bandage muss sehr sorgfältig
geschehen und ist oft Ursache für
Ausfälle,
die durch das Ablösen
der Bandenden entstehen. Eine Lösung
zur Sicherung der Bandenden durch zusätzliche Endscheiben und Sicherungsringe
ist in der Patentschrift
Die
Fixierung von Anfang und Ende des Bandes der Bandagenwicklung bestimmen
die Zuverlässigkeit
des Läufers

des Betriebes. Die Fixierung bestimmt aber auch die erreichbare
Vorspannung und damit direkt das Leistungsvermögen der Läufereinrichtung. Die in der
Patentschrift
Aufgabenstellungtask
Der im Patentanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, den Bandanfang und das Bandende einer Bandage für einen Läufer mit außenliegenden Permanentmagneten besser zu fixieren und eine höhere Vorspannung, der direkt auf die Permanentmagnete gewickelten Bandage, zu ermöglichen.Of the The invention defined in claim 1 is based on the object the beginning of the band and the band end of a bandage for a runner with external permanent magnets better to fix and a higher one Preload, the bandage wound directly on the permanent magnets, to enable.
Erfindungsgemäß wird diese
Aufgabe gelöst durch
eine Läufervorrichtung
für elektrische
Maschinen mit einer zylindrischen Läuferpaketeinrichtung (
Darüber hinaus wird die obige Aufgabe gelöst durch ein Verfahren zum Herstellen einer Läufereinrichtung durch Bereitstellen einer zylinderförmigen Läuferpaketeinrichtung, Anordnen mehrerer Permanentmagnete am Außenumfang der Läuferpaketeinrichtung und dem Fixieren der Permanentmagnete am Außenumfang der Läuferpaketeinrichtung durch eine Bandage, die neben den Permanentmagneten als Ring mit einer stärker Wandstärke ausgebildet ist.Furthermore the above task is solved by a method of manufacturing a rotor device by providing a cylindrical Rotor core facility Arranging a plurality of permanent magnets on the outer circumference of the rotor core device and the fixing of the permanent magnets on the outer circumference of the rotor package means a bandage, in addition to the permanent magnets as a ring with a stronger Wall thickness is trained.
In vorteilhafter Weise können durch die Erfindung sichere Fixierungen von Anfang und Ende der Bandagenwicklungen in den neben den Permanentmagneten befindenden Ringwicklungen erfolgen. Anfang und Ende der Bandage können dementsprechend während des Herstellungsprozesses selbst überwickelt und fixiert werden. Damit ist kein zusätzlicher Fertigungsschritt zu Sicherung von Anfang und Ende erforderlich. Durch die neue Anordnung ist es möglich, die hohe Festigkeit der Faserverbundbänder vollständig auszunutzen und die so gefertigten Läuferpaketeinrichtungen bei höheren Drehzahlen zu betreiben.Advantageously, secure fixing of the beginning and end of the bandage windings in the ring windings located next to the permanent magnets can be achieved by the invention. The beginning and end of the bandage can accordingly be wrapped and fixed during the manufacturing process itself. There is no extra Licher manufacturing step to backup from beginning and end required. The new arrangement makes it possible to fully exploit the high strength of the fiber composite tapes and to operate the rotor package devices thus produced at higher speeds.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen. In vorteilhafter Weise können für die Bandage Glasfasern eingesetzt werden, diese sind im Vergleich zu Kohlenstofffasern leicht biegsam. Kohlenstofffasern neigen durch ihre hohe Sprödigkeit beim Wickeln über scharfe Kanten zum Bruch. In vorteilhafter Weise wird ein heißhärtendes Epxoidharz eingesetzt, da damit eine bessere Festigkeit bei höheren Temperaturen erreicht wird.advantageous Further developments of the invention will become apparent from the dependent claims. In can advantageously for the Bandage glass fibers are used, these are compared to Carbon fibers easily bendable. Carbon fibers tend through their high brittleness when winding over sharp Edges to break. Advantageously, a thermosetting Epoxy resin used, as it allows better strength at higher temperatures is reached.
In vorteilhafter Weise werden die Glasfasern bei der Tränkung mit dem heißhärtenden Epoixidharz erwärmt und dann auf das kalte Läuferpaket gewickelt. Durch die Temperaturdifferenz zwischen Fasern und Läuferpaket wird die Vorspannung der Bandage vergrößert.In Advantageously, the glass fibers in the impregnation with the thermosetting one Epoixide resin heated and then on the cold runner package wound. Due to the temperature difference between fibers and rotor core the pretension of the bandage is increased.
