Abstract

The base (7') supported on, and fixed to, the tubular mast (7) serves as a mounting for the rotor (2) and for independent and individually supported stator rings (7'') which can co-operate selectively with the outer pole ring (9) coupled to the rotor (2). The outer pole ring (9) overlaps all inner stator rings (8''') uniformly so that one or more of the annular generators (8) can be utilised. Base and mast may be of reinforce concrete. ADVANTAGE - Magnetic or pneumatic control elements mounted on fixed base are more easily accessible, and massive outer pole ring increases stability.

Description

Angesichts der sich in den letzten Jahren ergebenden Sachlage auf dem Energiesektor, kann man davon ausgehen, daß es wahrscheinlich schon bald keine Nuklear-Energie mehr geben wird. Mit Sicherheit wird auch der kosten­ günstige Sonnenkollektor so bald nicht kommen, wahrscheinlich nach Ansicht von Fachleuten gar nicht, da er sehr materialintensiv ist. Infolge der sich dramatisch entwickelnden Klimaverschiebung, die neuerdings große und langanhaltende Sturmphasen bringt, ergibt sich für eine neue Windenergie, die sturmgesichert ist und bei der die Turbine bei Sturm nicht mehr abgestellt werden muß ein völlig neuer Stellenwert.In view of the situation that has arisen in recent years on the Energy sector, one can assume that it will probably be soon will no longer give nuclear energy. It will certainly cost too cheap solar panel not coming soon, probably after Not at all from experts, since it is very material-intensive. As a result of the dramatically developing climate shift, the more recently brings large and long-lasting storm phases results for a new one Wind energy that is protected against storms and that does not have the turbine during a storm more must be turned off a completely new status.

Hierzu legt die Erfindung ein neues Konzept vor. Es wird eine kostengünstige Großwindanlage geben, die bei Sturm weiterläuft und da das neue System einige Sturmproben schon überstanden hat, wird es eine gute Alternative für die Zukunft sein.To this end, the invention presents a new concept. It will be an inexpensive one Give large wind turbine, which continues in storm and since the new system some Survived storm tests, it will be a good alternative for that Be future.

Entgegen zur ersten Lösung, bei der die einzelnen Statoren des Generators fest mit dem Mast (7) verbunden sind, wird bei dieser Zusatzanmeldung jeder der Statoren einzeln gelagert und kann wahlweise mit dem Polaußenring, der mit dem Rotor gekoppelt ist, in Funktion treten. Der Polaußenring über­ deckt einheitlich alle Statorringe, so daß neben dem Freilauf ein oder mehrere der Ringgeneratoren eingesetzt werden können. Diese Lösung hat den Vorteil, daß die auf der stehenden Fundamentbasis (7) montierten magnetischen oder pneumatischen Steuerelemente leichten Zugang haben. Der mit dem Rotor verbundene Polaußenring stellt für die weitere Stabilisierung, durch seine Masse, neben dem Kreisel, der, je schneller er läuft, umso mehr Leistung bringt.Contrary to the first solution, in which the individual stators of the generator are firmly connected to the mast ( 7 ), each of the stators is stored individually with this additional application and can optionally function with the pole outer ring, which is coupled to the rotor. The outer pole ring covers all stator rings uniformly, so that one or more of the ring generators can be used in addition to the freewheel. This solution has the advantage that the magnetic or pneumatic control elements mounted on the standing foundation base ( 7 ) have easy access. The pole outer ring connected to the rotor provides for further stabilization, due to its mass, next to the gyroscope, which, the faster it runs, the more power it delivers.

Ebenso wie das Fundament kann auch der Rohrmast in Stahlbeton ausgeführt sein.Just like the foundation, the tubular mast can also be made of reinforced concrete be.
