Abstract

A linear generator for power generation in a wave-driven power station is provided. The linear generator includes a primary part which has a plurality of annular primary coils, which are arranged concentrically with respect to an axis and are separated from one another by intermediate elements, and a secondary part which has a plurality of secondary coils, to which direct current can be applied. The secondary coils are arranged axially alongside one another with alternating polarity and have superconductor windings. The the arrangement of the primary coils in the primary part is in the form of an air-gap winding with intermediate elements composed of non-magnetizable material. The primary part or the secondary part is moved parallel to the axis, in an externally operated manner, by a buoy and the current which is induced in the primary coils by the relative movement between the primary part and the secondary part can be tapped off for power generation.
