A novel permanent magnet tubular linear generator for ocean wave energy

This paper presents a novel permanent magnet tubular linear generator (PMTLG) buoy system designed to convert the linear motion of the ocean waves into electrical energy. The design incorporates no working seals and a salt water airgap bearing surface integration between PMTLG buoy components. The internal generator design will be discussed, in addition to the system integration with the buoy structure and the linear test bed performance results.
