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.
