Abstract

The device has radial magnetic block (4) around a shaft (2) and flux guidance parts (5) of essentially circular segment-shaped cross-section held between 2 cover plates by rod-shaped holding elements (31) fed via apertures (52) in the flux guidance parts and joined to the cover plates. The holding elements and cover plates are in the form of a one-piece injection-molded part of plastic or other non-magnetic, electrically non-conducting material.

Description

  • Die Erfindung betrifft einen Permanentmagnet-Rotor für eine elektrische Maschine, bei dem strahlenförmig um eine Welle angeordnete Magnete und dazwischen angeordnete Flussleitstücke mit im wesentlichen kreissegmentförmigem Querschnitt zwischen zwei mit der Welle verbundenen Deckscheiben gehalten und mittels stabförmiger Halteelemente fixiert werden, die durch Aussparungen in den Flussleitstücken geführt und mit den Deckplatten verbunden sind. The invention relates to a permanent magnet rotor for an electric machine, radially arranged at the about a shaft magnets and disposed therebetween flux conductors having a substantially circular segment cross-section between two kept connected to the shaft cover plates and are fixed by means of rod-shaped holding elements which by recesses in the flux guide pieces are guided and connected to the cover plates.
  • Ein Permanentmagnet-Rotor dieser Bauart ist beispielsweise aus der DE 35 17 883 A1 bekannt. A permanent magnet rotor of this type is known for example from DE 35 17 883 A1. Dabei werden wegen der einfachen Geometrie Ferritmagnete mit rechteckigem Querschnitt strahlenförmig um eine Welle herum angeordnet. In this case, because of the simple geometry of ferrite magnets are arranged with a rectangular cross-section radially around a shaft. Zur Erhöhung des magnetischen Flusses werden zwischen den Magneten Flussleitstücke aus geschichteten Blechsegmenten eingesetzt, die durch Vorsprünge gleichzeitig zur Halterung der Magnete in radialer Richtung dienen. In order to increase the magnetic flux flux conducting elements are used of layered sheet metal segments between the magnets, which are used by projections at the same time for holding the magnets in the radial direction. Um einen magnetischen Rückschluss über die Welle zu vermeiden, muss diese aus nichtmagnetischem Material gefertigt sein, was sehr teuer ist. To avoid a magnetic yoke through the shaft, it must be made of non-magnetic material, which is very expensive. Alternativ können an der Welle zwei Deckscheiben aus magnetisch nichtleitendem Material befestigt werden, zwischen denen Segmente und Magnete koaxial und mit Abstand zur Welle befestigt werden. Alternatively, two cover plates may be fixed from a magnetically non-conductive material to the shaft, are attached between those segments and magnets coaxially and at a distance from the shaft. Da bei hohen Drehzahlen starke Fliehkräfte auf die Segmente und auf die Magnete wirken, erfolgt die Befestigung zwischen den Deckscheiben durch Bolzen oder andere stangenförmige Halteelemente, die durch Öffnungen in den Segmenten hindurchgeführt und mit den Deckscheiben verbunden sind (bei der DE 35 17 883 A1 werden in Nuten geführte Keile verwendet). Since strong centrifugal forces act at high speeds on the segments and on the magnets, the attachment between the cover plates by bolts or other rod-shaped holding elements, which are passed through openings in the segments and connected to the cover plates is carried out (35 17 883 A1, in DE used in grooves guided wedges).
  • Der klassische Einsatz eines solchen Permanentmagnet-Rotors mit Flusskonzentration erfolgt in elektrischen Maschinen, die Statoren mit eingezogener Wicklung besitzen. The classic use of such a permanent magnet rotor flux concentration occurs in electrical machines that have stators with drawn-winding. Bei Antrieben, bei denen eine große Drehzahlspreizung erforderlich ist, beispielsweise für Waschmaschinen, besteht der Wunsch, anstelle der eingezogenen Wicklung eine Einzelpolwicklung zu verwenden. On drives in which a large speed spread is required, such as for washing machines, there is a desire to use a single pole instead of the drawn-winding. Hierdurch entsteht folgendes Problem: This gives rise to the following problem:
    In der Einzelpolwicklung wird zusätzlich zur sinusförmigen Speisespannung eine Spannung mit doppelter Frequenz induziert. In the single pole voltage at twice the frequency is induced in addition to the sinusoidal supply voltage. Bei einer elektrischen Verbindung zwischen den Bolzen und den Deckplatten wirkt der vorbeschriebene Aufbau des Rotors aus Deckplatten und Bolzen wie ein Käfigläufer, in dem Ströme induziert werden. In an electrical connection between the bolts and the cover plates of the above-described construction of the rotor from the cover plates and bolts acts like a squirrel cage, are induced in the streams. Dies führt zu Oberwellen und Leistungsverlusten. This results in harmonics and power losses. Zur Vermeidung dieses Phänomens könnte eine Isolation im Verbindungsbereich zwischen Bolzen und Deckplatten verwendet werden. To avoid this phenomenon, an isolation in the connecting area between the pin and cover plates could be used. Hierdurch entsteht ein in der Fertigung aufwendiger Aufbau, da viele Einzelteile verwendet werden. This creates a more complex in production design, since many items are used.
