Description

Rotor zum Umwandeln der Energie des natürlichenRotor to convert the energy of the natural

Windes in nutzbare elektrische Energie Die Erfindung betrifft einen Rotor zum Umwandeln der Energie des natürlichen Windes in nutzbare elektrische Energie, bestehend aus einem Windrotor vorzugsweise aus einem Wrtikal-Doppel-Rotor der modernen aerodynamischen Art z.B. dem Hansen-Vertikal-Doppel-Rotor und einem Generator, der als Ringgenerator in die untere Endscheibe integriert ist.Wind into usable electrical energy The invention relates to a Rotor for converting the energy of the natural wind into usable electrical energy, consisting of a wind rotor, preferably a modern double rotor aerodynamic type e.g. the Hansen vertical double rotor and a generator, the is integrated as a ring generator in the lower end plate.

Rotoren dieser Art sind seit langem in vielen Variationen bekannt. Einachser: Savoniusrotor, Dariusrotor u.s.w.Rotors of this type have long been known in many variations. Single-axle: Savonius rotor, Darius rotor, etc.

Zweiachser: Hansen-Vertikal-Doppel-Rotor, Krüger-Rotor, Herter-Rotor, Burgdorf-Rotor, Christie-Rotor u.s.w.Two-axis: Hansen vertical double rotor, Krüger rotor, Herter rotor, Burgdorf rotor, Christie rotor etc.

Hbrizontalachser: z.B. Growian Rotoren dieser Arten benötigen ein Übersetzungsgetriebe zum Antrieb von Generatoren, da Elektrogeneratoren höhere Drehzahlen benötigen,als die Windrotoren sie zu leisten vermögen. Das kostet einen Teil der Windenergie. Bei niedriger Windgeschwindigkeit macht sich dieses besonders negativ bemerkbar.Hbrizontalachser: e.g. Growian rotors of these types need a Transmission gear for driving generators, as electric generators have higher speeds need than the wind rotors to do it capital. It costs part of the wind energy. This is done at low wind speeds particularly noticeable negatively.

Bei den Vertikal-Doppel-Rotoren kommt noch ein weiterer negativer Aspekt hinzu: es werden: weitere Getriebe für die Synchronisierung der beiden Vertikalrotoren benötigt, welches wieder einen Teil der Windenergie b;enötigt, was sich wiederum besonders bei niednger Windgeschwindigkeit negativ bemerkbar macht. Alle Getriebe verursachen Geräusche, die oft sehr störend empfunden werden und einen Betrieb in Wohngebieten ausschließen. Die Windrotoren aller Arten und Typen konnten sich, weil sie zu teuer sind, auf dem Markt nicht durchsetzen.With the vertical double rotors there is another negative one Another aspect: there will be: additional gears for synchronizing the two vertical rotors needed, which again b; needs part of the wind energy, which in turn especially noticeable at low wind speeds. All gears cause noises that are often very annoying and cause operation Exclude residential areas. The wind rotors of all kinds and types could turn out because they are too expensive to fail on the market.

Aufgabe der Erfindung war es daher, Rotoren zu schaffen, die die Energie des natürlichen Windes in nutzbare Energie umwandeln, die geräuschlos sind, einen besseren Wirkungsgrad haben und ohne die oben erwähnten Nachteile arbeiten.The object of the invention was therefore to create rotors that generate the energy converting the natural wind into usable energy that is noiseless, one have better efficiency and work without the disadvantages mentioned above.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Übersetzungs und Synchronisierungsgetriebe vollkommen entfallen. Die Vertikal-Rotoren erhalten mind.estens unten Endscheiben, die dafür sorgen, daß das Nutzungsverhältnis wesentlich verbessert wird. Ohne Endscheiben geht ein Teil der Windströmung oben und unten verloren (Höhen-Breitenverhältnis). Dieses wurde im Wind.According to the invention, this object is achieved in that the translation and synchronization gears are completely eliminated. The vertical rotors received at least at the bottom end plates, which ensure that the usage ratio is substantial is improved. Without end caps, part of the wind flow goes up and down lost (height-width ratio). This was in the wind.

kanal bei den Flettnerrotoren eingehend untersucht.duct examined in detail at the Flettner rotors.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß die untere Endscheibe als Rotor im Sinne eines Synchron-oder Asynchron-Elektromotors ausgebildet wird. Der Stator und. die Drehstromwicklung werden U förmiig über den äußeren Rand des Rotors (Endscheibe unten) angebracht, sodaß das Drehfeld der Stern- oder Dreieckswicklung linear in Drehrichtung des Vertikal-Windrotors wirkt. Die Windrotoren sind so in der Lage, die Energie berührungslos und geräuschlos und ohne Getriebe direkt an den Verbraucher oder an das E-Netz abzugeben.In a further embodiment of the invention it is proposed that the lower end disk as a rotor in the sense of a synchronous or asynchronous electric motor is trained. The stator and. the three-phase windings are U-shaped over the outer edge of the rotor (end disk below) so that the rotating field of the star or triangular winding acts linearly in the direction of rotation of the vertical wind rotor. the Wind rotors are thus able to generate energy without contact and without making any noise Deliver the gearbox directly to the consumer or to the electrical network.

Um die Leistung des Windrotors der jeweiligen Windgeschwindigkeit anzupassen, wird in einer Weiterbildung der Erfindung vorgeschlagen, daß verschieden starke Wicklungen angebracht werden, die nach Bedarf automatisch zu- bzw. abgeschaltet werden.To the power of the wind rotor of the respective wind speed adapt, it is proposed in a development of the invention that different strong windings are attached, which are automatically switched on or off as required will.

Der Rotor (Endscheibe) kann durch seinen großen Umfang (3 - 30 m) problemlos jede elektrische Leistung abgeben, die der Rotor auch bei Sturm erzeugt.Due to its large circumference (3 - 30 m), the rotor (end disk) easily deliver any electrical power that the rotor generates even in a storm.

In weiterer Ausgestaltung der Er.findumg wird vorgeschlagen, daß bei Inselbetrieb der Rotor (Endscheibe) mit Permanent-Mag neten versehen wird, um netzunabhkngig auch kleinste Windgeschwindigkeiten in Nutzenergie umzuwandeln. Jedoch könnten auch hier große Leistungen erzeugt werden, da auf einer Länge von 3 - 30 m viele Permanentmagnete angebracht werd.en können.In a further embodiment of the invention it is proposed that with Island operation of the rotor (end disk) is provided with permanent magnets in order to be network-independent to convert even the smallest wind speeds into useful energy. However, could also Great power is generated here, as there are many permanent magnets over a length of 3 - 30 m can be attached.

Die Leistungsabnahme kann elektrisch genau auf die Leistungskurve des jeweiligen Windrotors angepasst werden.The decrease in power can be electrical exactly on the power curve of the respective wind rotor.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, den Rotor (Endscheibe) gleichzeitig als Bremsscheibe zu nutzen.In a further embodiment of the invention, it is proposed that the rotor (End plate) can also be used as a brake disc.

Durch den großen Durchmesser der Bremsscheibe ist ein problemloses Abbremsen auch bei Strrm möglich.Due to the large diameter of the brake disc, it is easy to use Braking is also possible when there is a storm.
