Novel design and implementation of a permanent magnet linear tubular\ud generator for ocean wave energy conversion

Graduation date: 2008The world’s energy consumption is growing at an alarming rate and the need\ud for renewable energy is apparent now more than ever. Estimates have shown that\ud optimization of the extraction of energy from the ocean could significantly aid the\ud world’s quest for sustainable and affordable energy services for all. From small power\ud data buoys to generating power for coastal communities, everyone stands to benefit\ud from the technological optimization of ocean wave energy devices. This thesis\ud explores the design and implementation of a novel permanent magnet linear generator\ud for direct drive ocean wave energy extraction point absorber buoys. The design\ud optimizes the armature and magnet sections of a permanent magnet linear tubular\ud generator (PMLTG) for the purposes of maximizing the energy conversion efficiency\ud while minimizing cogging forces. Cogging forces in a linear generator influence\ud power fluctuations and hydrodynamic performance of the wave energy extraction\ud system. Implementation techniques involving the construction and mechanical design\ud aspects are included
