Vorteile der ErfindungAdvantages of the invention
Der erfϊndungsgemaße Klauenpolmotor mit den Merkmalen des Anspruchs 1 hat den Vorteil, daß er sehr gut in das Innere eines anzutreibenden Geräts, insbesondere eines Lufterrads eines Lufters oder Geblases, integriert werden kann und somit keinen zusätzlichen Bauraum benotigt Aufgrund seiner Konusform laßt er sich vorteilhaft axial in das Gerat einschieben und an diesem mit seinem Rotor leicht befestigen, so daß eine gesonderte Rotorwelle entfallen kann und eine axial gedrängte Bauweise erzielbar ist. Insbesondere bei der Verwendung des Klauenpolmotors zum Antrieb des Lüfterrads eines Lüfters, z.B. m einem Klimagebläse, lassen sich die vom erfindungsgemäßen Klauenpolmotor gebotenen Vorteile optimal einbringen, da der Klauenpolmotor den gezwungenermaßen im Innern des Lüfterrads ohnehin vorhandenen Bauraum maximal ausnutzt und keine Veränderungen der Lüfterabmessungen erforderlich macht. Gegenüber herkömmlichen Lüftern für Klimageblase wird bei unverändert dimensioniertem Lüfterrad eine deutliche Reduzierung der Baulänge des Lüfters erzielt, die nunmehr nur noch durch die axiale Breite oder Tiefe des Lüfterrads bestimmt ist. Wird das Lüfterrad konstruktiv etwas modifiziert, so kann es zugleich zur Kühlung des Klauenpolmotors verwendet werden, so daß der Klauenpolmotor bei gleichen Abmessungen leistungsstarker ausgelegt werden kannThe claw-pole motor according to the invention with the features of claim 1 has the advantage that it can be integrated very well into the interior of a device to be driven, in particular an air wheel of a fan or blower, and thus does not require any additional installation space. Because of its cone shape, it can advantageously be axially inward insert the device and attach it slightly with its rotor, so that a separate rotor shaft can be omitted and an axially compacted one Construction is achievable. In particular, when using the claw-pole motor to drive the fan wheel of a fan, for example in an air conditioning blower, the advantages offered by the claw-pole motor according to the invention can be optimally introduced, since the claw-pole motor makes maximum use of the space that is necessarily present inside the fan wheel and does not require any changes in the fan dimensions , Compared to conventional fans for air conditioning bladders, the fan length is significantly reduced when the fan wheel is dimensioned unchanged, which is now only determined by the axial width or depth of the fan wheel. If the fan wheel is modified somewhat in terms of design, it can also be used to cool the claw-pole motor, so that the claw-pole motor can be designed more powerfully with the same dimensions
Durch die m den Ansprüchen 2 bis 10 aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen Klauenpolmotors möglich.Advantageous further developments and improvements of the claw-pole motor specified in claim 1 are possible through the measures listed in claims 2 to 10.
Em Lüfter mit integriertem Klauenpolmotor ist den Ansprüchen 11 bis 14 angegeben.Em fan with integrated claw-pole motor is specified in claims 11 to 14.
Ein besonders raumsparender Doppellüfter für ein Klimagebläse laßt sich mit den Merkmalen des Anspruchs 15 erzielen.A particularly space-saving double fan for an air conditioning fan can be achieved with the features of claim 15.

In the four-pole claw-pole motor designed as an example, each yoke 14 and 15 carries two diametrically arranged claws 16 and 17, respectively. The two yokes 14, 15 are assembled rotated by 90 °, so that the claws 16, 17 which extend over the belt coil 20 engage. To produce the toroidal coil 20, the coil body 21 is inserted with the radial flange 212 into the yoke 14 carrying the claws 16, the core 21 1 of the coil body 21 being pushed onto the sleeve 18. Then the coil body 21 is rotated by 90 °, so that the The radial flange 212 is congruent with the yoke 14. The yoke 15 carrying the claws 17 is then inserted with its sleeve 19 into the core 211 of the coil body 21 such that the claws 17 lie between the claws 16. The winding wire is then placed on the coil body 21 wound, whereby the cone-shaped Rmgspule 20 is formed
Der außenhegende Rotor 12 weist im Ausführungsbeispiel einen den Stator 11 konzentrisch umschließenden, konusformigen Ruckschlußπng 22 und eine der Anzahl der Klauen 16, 17 entsprechende Anzahl von Permanentmagnetpolen 23 auf, im Ausführungsbeispiel vier Permanentmagnetpole 23, die an der den Klauen 16, 17 zugekehrten Innenwand 221 des Rückschlußrings 23 anliegen. Wie m Fig 2 zu sehen ist, sind die Permanentmagnetpole 23 durch permanentmagnetische Schalensegmεnte gebildet, die in Umfangsrichtung zu einem hohlen Konus zusammengesetzt sind. Die Schalensegmente sind jeweils radial magnetisiert, wobei die Magnetisierungsπchtung in benachbarten Schalensegmenten entgegengeπchtet ist. Alternativ können die Permanentmagnetpole 23 auch durch einen geschlossen, konischen Permanentmagnetπng realisiert werden, der entsprechend magnetisiert ist. In einer modifizierten Ausfuhrung kann der Rückschlußrmg 23 entfallen. Die Permanentmagnetschalen werden dann poloπentiert magnetisiert.In the exemplary embodiment, the external rotor 12 has a conical shape 22 which concentrically surrounds the stator 11 and a number of permanent magnet poles 23 corresponding to the number of claws 16, 17, in the exemplary embodiment four permanent magnetic poles 23, which are attached to the inner wall 221 facing the claws 16, 17 the return ring 23 abut. As can be seen in FIG. 2, the permanent magnet poles 23 are formed by permanent magnetic shell segments which form a hollow cone in the circumferential direction are composed. The shell segments are each radially magnetized, the magnetization in opposite shell segments being opposed. Alternatively, the permanent magnet poles 23 can also be realized by a closed, conical permanent magnet which is magnetized accordingly. In a modified embodiment, the inference 23 can be omitted. The permanent magnet shells are then magnetized poloπentiert.
In der in Fig. 1 dargestellten emsträngigen Ausbildung des Klauenpolmotors ist es vorteilhaft, die Klauen 16, 17 asymmetrisch auszubilden, um einen definierten Anlauf des Klauenpolmotors zu gewährleisten. Die Ansteuerung der Ringspule 20 erfolgt bipolar Wünscht man eine unipolare Ansteuerung der R gspule 20, so wird die Rmgspule 20 aus zwei entgegengesetzt gewickelten Wicklungen zusammengesetzt, die auf den Spulenkörper 21 aufgewickelt sindIn the detailed design of the claw-pole motor shown in FIG. 1, it is advantageous to design the claws 16, 17 asymmetrically in order to ensure a defined starting of the claw-pole motor. The control of the ring coil 20 takes place bipolar. If a unipolar control of the ring coil 20 is desired, the ring coil 20 is composed of two oppositely wound windings which are wound on the coil body 21
Der hier beschπebene einstrangige Klauenpolmotor kann auch mehrstrangig z.B. zwei- oder dreisträngig mit beliebiger Strangzahl ausgeführt werden, indem eine der Strangzahl entsprechende Anzahl von Motormodulen, die - wie m Fig. 1 dargestellt - aus Stator 11 und Rotor 12 zusammengesetzt sind, in Achsπchtung hintereinander angeordnet werden. Dabei sind im aufeinanderfolgenden Motormodulen die Statoren 11 gegeneinander verdreht, und zwar bei zwei Motormodulen um 90° elektπsch und bei m>2 Motormodulen um 360 m elektrisch. Die Rotoren 12 sind miteinander drehfest gekoppelt Ein axialer Abstand zwischen den einzelnenThe single-stranded claw-pole motor described here can also be multi-stranded, e.g. two or three-stranded with any number of strands are carried out by arranging a number of motor modules corresponding to the number of strands, which - as shown in FIG. 1 - are composed of stator 11 and rotor 12, arranged one behind the other in axial direction. In the successive motor modules, the stators 11 are rotated with respect to one another, specifically in the case of two motor modules by 90 ° electrically and in the case of m> 2 motor modules by 360 m electrically. The rotors 12 are rotatably coupled to one another An axial distance between the individual
Motormodulen sorgt für eine magnetische Entkopplung. Alternativ können anstelle der Statoren 11 die die Permanentmagnetpole 23 tragenden Rotoren 12 um die genannten Drehwinkel gegeneinander verdreht werden.Motor modules ensure magnetic decoupling. Alternatively, instead of the stators 11, the rotors 12 carrying the permanent magnet poles 23 can be rotated relative to one another by the rotation angles mentioned.
