Abstract
The invention relates to a wave-power unit for the production of electric power. It comprises a floating body arranged for floating on the sea and an electric linear generator with a stator () and a reciprocating translator (). The stator () is arranged to be anchored in the bed of a sea and the translator () is connected to the floating body by connection means, The translator () is journalled in a plurality of roiling elements () such that a circumferential gap () is formed between the stator and the translator. According to the invention each rolling element () has an elasticity that is low enough to meet the condition that a change in the width (d) of the gap results in a change in the total force from the roiling elements () that is larger than the total magnet forces on the translator resulting from the change in width (d). The invention also relates to a use of the invented wave-power unit.
