Dynamic magnetic field analysis and optimum design of small-sized wind power generator

The design and development of a small modular savonius-type wind power generator has been conducted since Oct., 1998. The characteristics are rare-earth permanent magnets a and core-less coil generator, savonius-type wind, and maximum power point tracking control. The Kochi University of Technology played a role of a design, and analysis of the generator. Undergraduate students shared the parts for design, and communicated with a manufacturer, who machined and assembled the generator. From the viewpoint of research interest, the dynamic magnetic field analysis has been conducted. In order to confirm the results by the analysis, a wind tunnel experiment was performed. The analytical result was within 10% error from the experimental result. The analysis is considered to be a tool for investigating the most suitable design for the generator. The small-sized wind power generator which was developed for design and manufacture is reported.
