Comparison Research on Axial Flux Modulation Generators for Linear-rotary Wave Energy Conversion

To improve the performance of generators used for Underwater wave energy converter, This paper proposed a linear-rotary axial flux modulation generator. The operation principle is analyzed. Four generators with different ratio of number of modulation teeth and permanent magnet pole are studied. The performances under no-load and on-load condition are comparison researched. An optimal axial flux modulation generator is obtained.
