Description

Die Erfindung bezieht sich auf einen Windgenerator, bestehend aus einem ersten Propeller, einem ersten von diesem angetriebenen Ro­ tor eines ersten Stromgenerators, einem zweiten Rotor, der den ersten Rotor umgibt, einem zweiten Propeller, der auf der zu dem ersten Propeller entgegengesetzten Seite des Generators angeordnet ist, den zweiten Rotor antreibt und sich und den zweiten Rotor entgegengesetzt zu dem ersten Propeller dreht.The invention relates to a wind generator consisting of a first propeller, a first Ro powered by this gate of a first power generator, a second rotor, the surrounds the first rotor, a second propeller that is on the to the first propeller arranged opposite side of the generator is, drives the second rotor and itself and the second rotor rotates opposite to the first propeller.

Bei einem bekannten Windgenerator dieser Art (FR 878 481, Fig. 1) ist nicht ein zweiter Generator vorgesehen. Infolgedessen ist die Stromausbeute begrenzt.In a known wind generator of this type (FR 878 481, Fig. 1), a second generator is not provided. As a result, the current efficiency is limited.

Der Erfindung liegt die Aufgabe zugrunde, die Stromausbeute des eingangs definierten Generators zu erhöhen.The invention is based, the current efficiency of the task to increase the initially defined generator.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß sich zwi­ schen dem zweiten Rotor und einem gerätefesten Gehäuse ein zweiter Generator befindet, daß dessen Rotor fest mit dem zweiten Rotor auf dessen Außenseite und dessen Stator fest mit dem Gehäuse ver­ bunden sind, daß sowohl der erste Rotor als auch der zweite Rotor aus Elektromagneten bestehen, und daß der von dem zweiten Genera­ tor gelieferte Strom in die Wicklungen der Elektromagnete des er­ sten oder zweiten Rotors des ersten Stromgenerators geleitet wird. This object is achieved in that between a second rotor and a device-fixed housing Generator is that its rotor is fixed to the second rotor ver on the outside and its stator firmly with the housing are bound that both the first rotor and the second rotor consist of electromagnets, and that of the second generation Tor delivered current in the windings of the electromagnets of the er most or second rotor of the first current generator is conducted.  

Auf diese Weise wird eine größere Stromausbeute des Generators erzielt.In this way there is a greater current efficiency of the generator achieved.

Hierbei ist folgendes zu beachten: Gewisse Stromgeneratoren beste­ hen aus Elektromagneten und Permanentmagneten. Der Strom kommt aus den Elektromagneten. Hat man eine zusätzliche Stromquelle zur Ver­ fügung, dann können die Permanentmagnete durch Elektromagnete er­ setzt werden, die dann von dem Strom der zusätzlichen Stromquelle gespeist werden. Diese Elektromagnete sind gegenüber den Perma­ nentmagneten vorteilhaft, da sie stärkere Magnetfelder erzeugen, was zu einer höheren Stromausbeute führt. Dieser Gedanke wird beim Erfindungsgegenstand ausgenutzt: Der zweite Generator liefert Strom. Der erste Stromgenerator besitzt anstelle mindestens eini­ ger Permanentmagnete Elektromagnete. In diese wird dieser Strom eingeleitet.Please note the following: Certain power generators are the best hen from electromagnets and permanent magnets. The electricity comes out the electromagnet. Do you have an additional power source to Ver Then the permanent magnets can be replaced by electromagnets are then set by the current of the additional power source be fed. These electromagnets are opposite to the perma Magnets advantageous because they generate stronger magnetic fields, which leads to a higher current efficiency. This is the thought of Object of the invention exploited: the second generator delivers Electricity. The first current generator has at least one instead ger permanent magnets electromagnets. In this is this stream initiated.

Fig. 2 einen Axialschnitt durch ein Gehäuse dieses Windgenerators. Fig. 2 shows an axial section through a housing of this wind generator.

Der in Fig. 1 veranschaulichte Windgenerator besteht aus einem Ständer 1, einem an dessen oberen Ende angeordneten Stromgenerator 2 und zwei entgegengesetzt zueinander rotierenden Propellern 3 und 4. Der die Propeller antreibende Wind kommt von rechts, siehe die Pfeile 5.The wind generator illustrated in FIG. 1 consists of a stator 1 , a current generator 2 arranged at its upper end and two propellers 3 and 4 rotating in opposite directions. The wind driving the propellers comes from the right, see arrows 5 .

Fig. 2 zeigt den zwischen den beiden Propellern angeordneten Gene­ rator 2. Dieser besteht aus einem Gehäuse 6. In diesem ist über ein Lager 7 eine Welle 8 gelagert, auf der ein erster Rotor 9 fest sitzt. Die Welle 8 bildet ein erstes Wellenende 10, das mit dem ersten Propeller 3 verbunden ist. Ein zweites Wellenende 11 ist über ein Lager 12 in dem Gehäuse 6 gelagert und mit dem zweiten Propeller 4 verbunden. Am Ende dieses zweiten Wellenendes 11 sitzt fest mit diesem verbunden ein zweiter Rotor 13. Auf der dem Welle­ nende 11 abgewandten Seite des zweiten Rotors 13 ist dieser über ein Lager 14 auf der Welle 8 gelagert. Letztere ist ihrerseits auf der rechten Seite der Fig. 2 über ein Lager 15 an dem zweiten Ro­ tor 13 gelagert. Die Relativbewegungen zwischen zweitem Rotor 13 und erstem Rotor 9, die zur Stromerzeugung führen, spielen sich diesseits und jenseits des Spaltes 16 ab. Fig. 2 shows the arranged between the two propellers generator 2 . This consists of a housing 6 . In this, a shaft 8 is mounted on a bearing 7 , on which a first rotor 9 is seated. The shaft 8 forms a first shaft end 10 , which is connected to the first propeller 3 . A second shaft end 11 is mounted in the housing 6 via a bearing 12 and connected to the second propeller 4 . At the end of this second shaft end 11 , a second rotor 13 is firmly connected to it. On the shaft end 11 facing away from the second rotor 13 , this is mounted on the shaft 8 via a bearing 14 . The latter is in turn mounted on the right side of FIG. 2 via a bearing 15 on the second ro tor 13 . The relative movements between the second rotor 13 and the first rotor 9 , which lead to the generation of electricity, take place on both sides of the gap 16 .

Der Generator 2 weist einen Stator 17 und einen weiteren Rotor 18 auf, die ebenfalls der Stromerzeugung dienen, wobei in diesem Fal­ le der Stator 17 gehäusefest ist, so daß die Relativgeschwindig­ keit zwischen den Teilen 17 und 18 etwa halb so groß ist wie zwi­ schen den Teilen 13 und 9.The generator 2 has a stator 17 and a further rotor 18 , which also serve to generate electricity, in which case the stator 17 is fixed to the housing, so that the relative speed between the parts 17 and 18 is approximately half as large as between parts 13 and 9 .

Der weitere Rotor 18 sitzt fest auf der Außenseite des zweiten Rotors 13.The further rotor 18 is firmly seated on the outside of the second rotor 13 .

Der erste Rotor 9 und der zweite Rotor 13 weisen Elektromagnete auf. Der von dem zweiten Generator 17, 18 gelieferte Strom wird in die Wicklungen der Elektromagnete des ersten Rotors 9 oder des zweiten Rotors 13 des ersten Stromgenerators eingeleitet.The first rotor 9 and the second rotor 13 have electromagnets. The current supplied by the second generator 17 , 18 is introduced into the windings of the electromagnets of the first rotor 9 or of the second rotor 13 of the first current generator.
