Characterization and optimization of a novel electromagnetic transduction technique for rotational energy harvesting

A novel transduction technique that converts mechanical rotation energy to usable electrical energy using condensed magnetic flux is tested and characterized for a wind source. This rotation harvester is compared to the power output of a commercially available generator for a fixed wind source. Optimization of the rotation harvester is discussed in terms of various parameters, such as magnet spacing, number of excitation arms, rotation frequency, and harvester resonance.
