A linear generator for submerged use in generating electricity has a linearly reciprocating translator which is attached to a wire and a rod arranged to connect the translator to a floating body on the sea surface. The generator has a sealed housing forming a watertight chamber in which the translator is located. The rod is arranged to pass through a sealed opening in a wall portion of the housing. When operated, the wall portion with the sealed opening is located at a level that is below the level of the upper end of the translator at least during a part of the movement of the translator.

Linear generator for submerged use and a method of producing electric energy

The invention relates to a stator frame () for a submerged linear generator. According to the invention the stator frame () includes a cylindrical tube of metal with mounting means () for mounting stator packages to the inside wall of the tube. The stator frame () also is the external circumferential wall of the linear generator. The invention also relates to the use of such a stator frame () and to a method for manufacturing a linear generator with such a stator frame ().

Stator frame for a submerged linear generator

The invention relates to a wave power unit having a submerged station anchored on the sea bottom, a floating body floating on the sea surface and flexible connection means () connecting these. The submerged station has a linear generator with a reciprocating translator. According to the invention, the station includes a guiding device () for the flexible connection means (). The guiding device () has a plurality of rotatable rollers (-). The rollers (-) form a passage for the flexible connection means (). The invention also relates to use of the wave power unit and to a method for producing electric power.
