Current and Future Developments of the C-GEN Lightweight Direct Drive Generator for Wave & Tidal Energy

The C-GEN is a novel permanent magnet generator aimed at reducing overall system mass in direct dri ve power takeoff applications. The design of a C-GEN generator requires the combination of electromagnet ic, structural and thermal models. Two rotary prototype s of 15 & 20kW have been constructed and tested and t he 15kW prototype has been fitted to a wind turbine. A 1kW linear generator has been tested and is being modified for flooded operation meanwhile a larger 50kW prototype is being designed. A feasibility stu dy of C-GEN technology in four different wave and tida l projects is being undertaken.
