Patent ID: 8154144

Claim:
A linear generator for power generation in a wave-driven power station comprising: a primary part having a plurality of annular primary coils arranged concentrically with respect to an axis and separated from one another by intermediate elements, and a secondary part having a plurality of secondary coils applicable with direct current and arranged axially alongside one another with alternating polarity and having superconductor windings, wherein the arrangement of the primary coils in the primary part is in the form of an air-gap winding with the intermediate elements composed of non-magnetizable material, and the secondary coils comprise windings of a high-temperature superconductor, as a result of which force densities of more than 18 N/cm 2 can be achieved, wherein the secondary coils are annular and are arranged concentrically with respect to one another around a supporting body, wherein spacing elements are arranged between the secondary coils, on which spacing elements the secondary coils are supported in the axial direction, wherein one of the primary part and the secondary part can be moved parallel to the axis, in an externally operated manner, by a buoy of a wave-driven power station and current which is induced in the primary coils by the relative movement between the primary part and the secondary part is tapped off for power generation.
