The invention relates to an energy generation plant for obtaining electric energy from a wind or water current, comprising: a turbine; an electric generator with a coaxial arrangement of the rotor and stator, the rotor being an external rotor and forming part of an annular supporting structure for the turbine and the stator being held in a stator housing that is sealed off from the surrounding medium. A wall region of the sealed stator housing runs in the vicinity of the gap between the rotor and the stator in such a way that the rotor lies radially outside the sealed stator housing and the magnetic interaction between the rotor and the stator takes place through said wall region; a bearing for the annular supporting structure which comprises the rotor, said bearing bordering the gap between the rotor and the stator and being supported on the outer periphery of the sealed stator housing.
L'invention concerne une installation de production d'énergie servant à produire de l'énergie électrique à partir d'un courant d'eau ou d'air et comprenant : une turbine; un générateur électrique à agencement coaxial du rotor et du stator, le rotor étant un rotor externe et faisant partie d'une structure d'appui annulaire pour la turbine, le stator étant logé dans un carter étanchéifié par rapport au milieu environnant et une zone de paroi du carter de stator étanchéifié s'étendant dans la zone de l'entrefer entre rotor et stator de sorte que le rotor se situe radialement à l'extérieur du carter de stator étanchéifié et que l'interaction magnétique entre le rotor et le stator se fait à travers cette zone de paroi; un logement pour la structure d'appui annulaire comprenant le rotor, ce logement étant adjacent à l'entrefer entre le rotor et le stator et s'appuyant sur la périphérie externe du carter de stator étanchéifié.
