An ocean wave energy converter system comprises an armature and a plurality of magnets which move relative to each other in response to ocean waves pushing on a spar and/or float to which the armature and the plurality of magnets are coupled. Components of the system comprise stacked rings and/or radial laminations. The armature can feature a variety of pole tips. Various methods can be used to assemble components from radial laminations. Air gaps in wire coils of the armatures can be filled with one or more materials that selectively alter the magnetic permeability of the wire coils. L'invention concerne un système qui permet de convertir l'énergie marémotrice. Ledit système comporte un induit et une pluralité d'aimants qui se déplacent les uns par rapport aux autres en réponse au mouvement de l'eau et poussent sur un longeron et/ou un flotteur auquel sont couplés l'induit et la pluralité d'aimant. Le système comporte également des anneaux empilés et/ou des tôles radiales. L'induit peut présenter divers embouts polaires. Divers procédés peuvent être utilisés pour assembler les composants à partir de tôles radiales. Des espaces d'air dans des bobines de fil de l'induit peuvent être remplis d'un ou de plusieurs matériaux qui modifient sélectivement la perméabilité magnétique des bobines de fil.
