Abstract: Provided is a rotor for an electric generator comprising a cylindrical casing part and a connecting structure to connect the casing to a rotor shaft. The structure comprises at least one plane disc composed of a plurality of plane disc elements which comprise disc elements that engage lockingly into each other, wherein a first and a second disc element comprise a complementary shape, where the two discs meet, with at least one protrusion on the first disc element and a corresponding number of recesses of the same shape at a complementary position on the second disc element. A protrusion on the first disc element engages a recess in the other disc element, where the protrusion has a varying width with a first portion at a distal end that is broader than a second portion proximal to a base of the disc element to create a shape-permanent locking engagement.

Abstract: A wind-power unit with a wind turbine, a generator with vertical axis a supporting pillar which supports the wind turbine, and a foundation for the supporting pillar (2). The generator includes a stator which is integrated with the foundation.

Abstract: The invention relates to a wind-power unit having a turbine having a vertical turbine shaft (3), an electrical generator (6) connected to the turbine and a vertical hollow supporting pillar (2) supporting the turbine. According to the invention the material of the supporting pillar is in all essentials wood. The invention also relates to a supporting pillar for such a wind-power unit, an electric mains connected to the wind-power unit, a use of the wind-power unit and a method for the manufacture of such a supporting pillar.

Abstract: A wind-power unit has a wind turbine has an electric generator connected to the wind turbine. The stator of the generator has a winding formed of a high-voltage cable having a core of conducting material, a first layer of semiconducting material surrounding the core, an insulating layer of solid material surrounding the first layer, and a second layer of semiconducting material surrounding th solid insulation. The wind turbine has a plurality of turbine blades running vertically and being connected to a turbine shaft. The generator is arranged at the lower end of the turbine shaft. A wind-power plant; the use of a wind-power unit; and a method of generating electric power are described.
