Abstract

Direct drive generators have the potential to simplify Wave Energy Converters (WEC) and increase reliability. In the last couple of decades several technologies proposing direct drive linear generators for wave energy converters have been proposed. In this paper a review of the current technologies for direct drive generators is carried out. Moreover, the most common magnetisation types for permanent magnets used in linear machines are reviewed.
