  • Abstract The purpose of this research is to provide systematic design of a permanent magnet (PM) generator, by adopting the double-rotor and the coaxial magnetic gear structural concept, which is suitable for harvesting the wind energy or the marine tidal energy directly without mechanical conversions. In addition to the physical model realizations, this research will present the detailed design and implementation concerns of the magnetic-geared double-rotor PM generator along with thorough loss assessments. The comparisons of PM magnetization directions and arrangements at different rotors, the selections of proper coils and windings, and the operational efficiencies of this machine along with terminal voltage phase shifts due to different loading conditions will all be summarized and confirmed by finite element analyses (FEA). The realization process of a portable 2.5 kVA generator that can be directly coupled to the driven source without additional mechanical gears will be demonstrated, and the feasibility of such a machine structure can certainly be confirmed from the satisfactory performance results.
