Description
Mechanische Spannungsregelung für PermanentmagnetgeneratorenMechanical voltage control for permanent magnet generators
Die Erfindung betrifft eine Einrichtung zur. Spannungsregelung von Generatoren mit Permanentmagneten.The invention relates to a device for regulating the voltage of generators with permanent magnets.
Permanentmagnetgeneratoren haben die Eigenschaft, daß sie je nach Belastung eine unterschiedliche Spannung liefern. Die meisten elektrischen Verbraucher erfordern eine elektrische Spannung, die relativ stabil sein muß und nur einige Prozent schwanken darf. Dieses Problem wird in der Regel durch folgende Maßnahmen gelöst:Permanent magnet generators have the property that they supply a different voltage depending on the load. Most electrical consumers require an electrical voltage that must be relatively stable and may only fluctuate by a few percent. This problem is usually solved by the following measures:
Spannungsregelung durch Regelelektronik Nachteile: relativ hohes Gewicht, komplizierte Schaltung, Beeinträchtigung des Gesamtwirkungsgrades durch Verlustwärme, grosses Bauvolumen durch Kühlflächen, aktive Kühlung durch Ventilator erforderlich, hohe Herstellungskosten, hohe Störimpulse, anfällig bei LaständerungenVoltage regulation by control electronics Disadvantages: relatively high weight, complicated circuit, impairment of the overall efficiency due to heat loss, large construction volume due to cooling surfaces, active cooling by fan required, high manufacturing costs, high interference pulses, susceptible to load changes

- Aufbau eines magnetischen Gegenfeldes Nachteile: ähnlich wie bei der Regelelektronik Regelung durch Drehzahländerung Nachteil: nicht anwendbar bei Antriebsaggregaten, die mit konstanter Drehzahl laufen (müssen).- Creation of a magnetic counter field Disadvantages: similar to control electronics Control by changing the speed Disadvantage: not applicable to drive units that (must) run at a constant speed.
- Änderung des Luftspaltes zwischen Permanentmagneten und Eisenkern Nachteile: großer Aufwand, teuer.- Changing the air gap between the permanent magnet and the iron core Disadvantages: great effort, expensive.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Spannungsregelung zu schaffen, die die angegebenen Nachteile vermeidet und auch bei hohen Generatorleistungen realisierbar ist.The invention is based on the object of creating a device for voltage regulation that avoids the stated disadvantages and can also be implemented at high generator outputs.

Die Erfindung wird nachfolgend anhand von Fig. näher erläutert.The invention is explained in more detail below with reference to Fig.
Es zeigen:Show it:
Fig. 1 eine Prinzipskizze in axonometrischer Darstellung,Fig. 1 a schematic diagram in axonometric representation,
Fig. 2 und 3 die magnetischen Kraftlinien und den Magnetfluß bei einem Permanentmagnetgenerator mit fluchtenden Magnetscheiben,Fig. 2 and 3 the magnetic lines of force and the magnetic flux in a permanent magnet generator with aligned magnet disks,
Fig. 4 und 5 die magnetischen Kraftlinien und den Magnetfluß bei einem Permanentmagnetgenerator mit radial gegeneinander verc/r£nr£f? Magnetscheiben.Fig. 4 and 5 show the magnetic lines of force and the magnetic flux in a permanent magnet generator with radially aligned magnetic disks.
Bei einem Zweischeibenläufer-Permanentmagnetgenerator 2 mit axialem Magnetfluß (Fig. 1) drehen sich die beiden Magnetscheiben 4 und 6 zu beiden Seiten des Stators 8, der aus Eisenkern und Spulen besteht. Die Magnete 10, 12, 14, 16 (Fig. 1 bis 3) liegen exakt mit den Polen Nord auf Nord und Süd auf Süd gegenüber. Dadurch wird erreicht, daß die Spulen 18, 20 von den magnetischen Feldern der Magnetscheiben 4 und 6 optimal von den magnetischen Kraftlinien durchflossen werden. In Fig. 3 sind die ansteigenden und abfallenden Stromflanken dargestellt.In a two-disk permanent magnet generator 2 with axial magnetic flux (Fig. 1), the two magnetic disks 4 and 6 rotate on either side of the stator 8, which consists of an iron core and coils. The magnets 10, 12, 14, 16 (Fig. 1 to 3) are exactly opposite each other with the poles north to north and south to south. This ensures that the magnetic fields of the magnetic disks 4 and 6 flow through the coils 18, 20 optimally, through the magnetic lines of force. The rising and falling current edges are shown in Fig. 3.
Werden die Magnetscheiben 4, 6 radial gegeneinander verdrenr; so ändert sich die Feldstärke der magnetischen Kraftlinien. Die Feldstärke, die auf die einzelnen Spulen wirkt, wird reduziert (Fig. 4). Daraus ergibt sich, daß die induzierte Spannung sinkt.If the magnetic disks 4, 6 are rotated radially against each other , the field strength of the magnetic lines of force changes. The field strength acting on the individual coils is reduced (Fig. 4). This results in the induced voltage falling.
In Fig. 5 ist die ansteigende und abfallende Stromflanke im zeitlichen Verlauf dargestellt. Der Regelbereich lag bei eine 5 kW-Testgenerator bei 60 % des Spannungsbereiches.Fig. 5 shows the rising and falling current edge over time. The control range for a 5 kW test generator was 60% of the voltage range.
