To Improve Micro-Planar-Magnetic Generator Performance Based on Addition of Magnetic Material

摘要

By finite element simulation and experiment, this paper compares the performance of generators with magnetic material to generators without magnetic material (Fe) in its coil and analyzes the reason why there is difference between simulation results and experimental results. Experimental results present that under the same rotational speed, output voltage improves 60% with the addition of magnetic material in coil compared to generator without magnetic material in coil. We further discuss the feasibility to add magnetic material in coil, present the existed problems and improvement methods.
