Abstract

The invention concerns a permanently excited transverse flux machine which requires only one permanent magnet segment per phase and per magnetic circuit. The magnetic flux generated by a permanent magnet segment (3) flows alternately through the soft-magnetic body on two conductor rings (7) of this transverse flux machine. The conductor rings (7) are disposed on different sides of the permanent magnet segment, the direction of flux in the permanent magnet segments corresponding to the direction of magnetic flux in the two air gaps through which said flux passes. Preferably, the permanent magnet segments are disposed between two U-shaped halves of a split tape core wound in a square manner, constituting the rotor bodies (5). The stator bodies (6) are also prefabricated from grain-oriented material as U-shaped split tape cores.

Description

Permanenterregte Transversalflußmaschine und Verfahren zu ihrer Herstellung Permanently excited transverse flux machine and method for its manufacture
Die Erfindung betrifft eine Transversalflußmaschine gemäß dem Oberbegriff des Anspruch 1 , sowie ein Verfahren zur Herstellung einer derartigen Maschine.The invention relates to a transverse flux machine according to the preamble of claim 1 and a method for producing such a machine.
Der Rotor bekannter permanenterregter Transversalflußmaschinen weist eine Vielzahl hart- und weichmagnetischer Segmente auf, deren Vorfertigung und Montage aufwendig ist. Durch die feingliedrige Struktur erhöht sich der Herstellungsaufwand, insbesondere wenn trotz der hohen Magnetkräfte ein schwingungsfreier Aufbau erreicht werden soll.The rotor of known permanently excited transverse flux machines has a large number of hard and soft magnetic segments, the prefabrication and assembly of which is complex. The delicate structure increases the manufacturing effort, especially if, despite the high magnetic forces, a vibration-free structure is to be achieved.
Der Erfindung liegt daher die Aufgabe zugrunde, eine permanenterregte Transversalflu߬ maschine und ein Verfahren zu ihrer Herstellung derart weiter zu bilden, daß mit geringem Material- und Herstellungsaufwand ein stabiler Maschinenaufbau erreicht wird.The invention is therefore based on the object of further developing a permanently excited transverse flux machine and a method for its manufacture in such a way that a stable machine structure is achieved with little expenditure on material and manufacture.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen der Ansprüche 1 und 6 gelöst. Erfindungsgemäß durchflutet der von einem Permanentmagnetsegment erzeugte magnetische Fluß abwechselnd die weichmagnetischen Köφer von zwei auf unterschiedlichen Seiten des Magneten angeordneten Leiterringen einer Transversalflußmaschine, wobei die Flußrichtung im Magneten mit der Flußrichtung in den beiden von ihm durchfluteten Luftspalten übereinstimmt. Vorzugsweise sind die Magnetsegmente zwischen zwei u-förmigen Hälften eines quadratisch gewickelten Schnittbandkemes angeordnet und auch die Statorkerne werden als u-förmigen Schnittbandkernen aus kornorientiertem Material vorgefertigt.This object is achieved with the features of claims 1 and 6. According to the invention, the magnetic flux generated by a permanent magnet segment alternately flows through the soft magnetic bodies of two conductor rings of a transverse flux machine arranged on different sides of the magnet, the direction of flow in the magnet coinciding with the direction of flow in the two air gaps through which it flows. The magnetic segments are preferably arranged between two U-shaped halves of a square wound core of the cutting tape and the stator cores are also prefabricated as U-shaped cutting cores made of grain-oriented material.
Der gesamte Maschinenaufbau zeichnet sich durch wenige unterschiedliche, einfach gestalte¬ te und vorzufertigende Bauteile aus, wobei mit geringem Aufwand eine hohe Stabilität im magnetischen aktiven Maschinenvolumen - insbesondere gegenüber den schwankenden Luft¬ spaltkräften - gewährleistet wird.The entire machine structure is characterized by a few different, simply designed and prefabricated components, a high stability in the magnetic active machine volume being ensured with little effort, in particular with respect to the fluctuating air gap forces.
Die Erfindung wird in den Zeichnungen anhand vorteilhafter Ausführungsformen dargestellt.The invention is illustrated in the drawings based on advantageous embodiments.
Fig. 1 zeigt den Längsschnitt einer dreiphasigen, permanenterregten Transversalflu߬ maschine als Innenläufer mit radialem Luftspaltfluß;1 shows the longitudinal section of a three-phase, permanently excited transverse flux machine as an internal rotor with a radial air gap flow;
Fig. 2 zeigt Querschnitte entsprechend den Linien I - I und II - II der 24-poligen Trans¬ versalflußmaschine aus Fig. 1;FIG. 2 shows cross sections corresponding to lines I - I and II - II of the 24-pole transverse flux machine from FIG. 1;
Fig. 3 zeigt den Längsschnitt einer zweiphasigen, permanenterregten Transversalflu߬ maschine als Innenläufer mit axialem Luftspaltfluß. Die Figur 1 dargestellte Transversalflußmaschine 1 weist drei baugleiche Rotorscheiben 2 auf in die Permanentmagnete 3 integriert sind, wobei die Magnete pro Phase nur einen Ring bilden und die Richtung des Flusses im Magneten und im Luftspalt 4 übereinstimmen. Die Magnete 3 sind zwischen zwei u-förmigen, weichmagnetischen Rotorkörper 5 angeordnet, die den Fluß konzentrieren, so daß die Flußdichte im Luftspalt deutlich höher als in den Magneten ist. Der von einem Magneten 3 erzeugte magnetische Kreis wird beim drehen des Rotors abwechselnd von einem axial links und rechts von der Rotorscheibe 2 angeordneten u-förmigen weich¬ magnetischen Statorkörpern 6 geschlossen. Innerhalb dieser Statorkörper 6 befinden sich in Umfangsrichtung verlaufende Leiterringe 7 aus Profildraht. Die in den beiden Luftspalten 4 eines Magnetkreises radial wirkenden Magnetkräfte sind durch die Zweiluftspaltanordnung kompensiert. Ein radiales Schwingen der Enden der weichmagnetischen Statorkörper 5 wird durch eine stabile Ausführung des Leiterrings 7 und durch eine starre Verstärkungsplatte 8 verhindert. Im Rotor nimmt ein im Mittelteil des radial äußeren Rotorkörpers 5 angeordneter Bandagering 9 die radial wirksamen Kräfte auf. Zusätzlich werden die weich- und hartmagneti¬ schen Teile 3, 5 der Rotorscheibe 2 miteinander verklebt, wobei axial angebrachte Ring¬ scheiben 10 die mechanische Stabilität und eine Kapselung der Magnet 3 gegen Umweltein¬ flüsse gewährleisten. In mehrphasiger Transversalflußmaschinen werden mehrere baugleiche Anordnungen durch Schrauben 11 - in Umfangsrichtung um den Bruchteil einer Polteilung zueinander versetzt - aneinandergefügt. Hierzu besteht der magnetisch passive Statorteil aus vier baugleichen inneren Gehäuseelementen 12 und zwei baugleichen Motorschildern 13. Die baugleichen Rotorscheiben 2 stecken auf einer Vierkantwelle 14. An den axial äußeren Enden sind Kugellager 15 abgeordnet und zwischen den Rotorscheiben vermeiden Wälzlager 16 radiale Schwingungen.3 shows the longitudinal section of a two-phase, permanently excited transverse flux machine as an internal rotor with an axial air gap flow. The transverse flux machine 1 shown in FIG. 1 has three identical rotor disks 2 in which permanent magnets 3 are integrated, the magnets forming only one ring per phase and the direction of the flux in the magnet and in the air gap 4 being the same. The magnets 3 are arranged between two U-shaped, soft-magnetic rotor bodies 5 which concentrate the flux, so that the flux density in the air gap is significantly higher than in the magnets. The magnetic circuit generated by a magnet 3 is alternately closed when the rotor is rotated by a U-shaped soft magnetic stator body 6 arranged axially to the left and right of the rotor disk 2. Within these stator bodies 6 there are conductor rings 7 made of profiled wire which run in the circumferential direction. The magnetic forces acting radially in the two air gaps 4 of a magnetic circuit are compensated for by the two-air gap arrangement. Radial oscillation of the ends of the soft magnetic stator body 5 is prevented by a stable design of the conductor ring 7 and by a rigid reinforcing plate 8. In the rotor, a band bearing ring 9 arranged in the middle part of the radially outer rotor body 5 absorbs the radially effective forces. In addition, the soft and hard magnetic parts 3, 5 of the rotor disk 2 are bonded to one another, with axially attached ring disks 10 ensuring the mechanical stability and encapsulation of the magnet 3 against environmental influences. In multi-phase transverse flux machines, several structurally identical arrangements are joined together by screws 11 - offset circumferentially by a fraction of a pole pitch. For this purpose, the magnetically passive stator part consists of four identical inner housing elements 12 and two identical motor shields 13. The identical rotor disks 2 are mounted on a square shaft 14. Ball bearings 15 are arranged at the axially outer ends and roller bearings 16 prevent radial vibrations between the rotor disks.
In Figur 2 sind Querschnitte gemäß den Schnittlinien I - I und II - π aus Figur 1 dargestellt. Beide 24-polige Statorhälften 17a,b sind baugleich und lediglich in Umfangsrichtung um eine Polteilung versetzt zueinander angeordnet. Die Anzahl der Statorkörper 6 pro Statorhälfte entspricht der halben Rotorpolzahl.FIG. 2 shows cross sections according to section lines I - I and II - π from FIG. 1. Both 24-pole stator halves 17a, b are identical in construction and only offset from one another in the circumferential direction by one pole pitch. The number of stator bodies 6 per half of the stator corresponds to half the number of rotor poles.
Für axial kürzere Baulängen empfiehlt sich die in Figur 3 dargestellte Transversalflußmaschine 20 mit axialem Luftspalt. Die Magnetkreisanordnung aus Figur 1 wird um 90° gedreht, wobei die vorteilhafte Materialausnutzung sowie der geringe Bauteilaufwand erhalten bleibt. Für die Maschinenmontage besteht der Stator 21 vorzugsweise aus zwei baugleichen Hälften 21a, b, die wiederum zwei unterschiedliche, druckgegossene Statorschalen 22, 23 aufweisen. Auch die u-förmigen, weichmagnetischen Statorkörper 24 bestehen hierbei vorzugsweise aus zwei Schnittkernteilen 25, 26, wobei die in den inneren Statorschalen 22 befestigten Stator¬ körperteile 25 vor dem axialen Befestigen der aus den Permanentmagneten 27 und u-förmigen, weichmagnetischen Rotorkörpern 28 vorgefertigten Rotorringen 29 positioniert werden. Anschließend werden die mit den restlichen Statorkörperteilen 26 bestückten äußeren Stator¬ schalen 23 axial mit den Lagern 30 aufgeschoben.For axially shorter lengths, the transverse flux machine 20 shown in FIG. 3 with an axial air gap is recommended. The magnetic circuit arrangement from FIG. 1 is rotated through 90 °, the advantageous material utilization and the low component expenditure being retained. For machine assembly, the stator 21 preferably consists of two identical halves 21a, b, which in turn have two different, die-cast stator shells 22, 23. The U-shaped, soft-magnetic stator bodies 24 here also preferably consist of two cut core parts 25, 26, the stator body parts 25 fastened in the inner stator shells 22 before the rotor rings 28 prefabricated from the permanent magnets 27 and U-shaped, soft-magnetic rotor bodies 28 are axially fastened 29 can be positioned. The outer stator shells 23 equipped with the remaining stator body parts 26 are then pushed axially with the bearings 30.
Wie in der Radialflußausführung in Fig. 1 können die Magnete 27 blockförmig ausgeführt sein. Die zum Luftspalt 31 weisenden Oberflächen müssen nun nicht nachgeschliffen werden. Die aus einem Leiterflachband 32 vorgefertigten Leiterringe 33 können zusammen mit ihrer auf der Luftspaltseite angeordneten Verstärkungshülse 34 montiert werden. Anstatt einstückig mit der Welle kann die T-förmige Rotorscheibe 35 auch aus mehreren Teilen vorgefertigt werden.As in the radial flux embodiment in FIG. 1, the magnets 27 can be designed in block form. The surfaces facing the air gap 31 now do not have to be reground. The conductor rings 33 prefabricated from a flat conductor strip 32 can be mounted together with their reinforcing sleeve 34 arranged on the air gap side. Instead of being made in one piece with the shaft, the T-shaped rotor disk 35 can also be prefabricated from several parts.
Ebenfalls möglich sind Varianten mit rotierenden Leiterringen und ortsfesten Magneten sowie Außenläuferbauformen . Variants with rotating conductor rings and fixed magnets as well as external rotor designs are also possible.
