Abstract

Energieerzeugungsanlage zur Gewinnung elektrischer Energie aus einer Wasser- oder Luftströmung, umfassend: eine Turbine; einen elektrischen Generator, mit einer koaxialen Anordnung von Läufer und Stator, wobei der Läufer ein Außenläufer und Teil einer ringförmigen Stützstruktur für die Turbine ist und der Stator in einem gegenüber dem Umgebungsmedium abgedichteten Statorgehäuse untergebracht ist und wobei ein Wandungsbereich des abgedichteten Statorgehäuses im Bereich des Spalts zwischen Läufer und Stator so verläuft, dass der Läufer radial außerhalb des abgedichteten Statorgehäuses angeordnet ist und die magnetische Wechselwirkung zwischen Läufer und Stator durch diesen Wandungsbereich hindurch erfolgt; eine Lagerung für die den Läufer umfassende ringförmige Stützstruktur, wobei die Lagerung angrenzend an den Spalts zwischen Läufer und Stator angeordnet ist und sich am Außenumfang des abgedichteten Statorgehäuses abstützt.
