| Abstract: | A design method of magnetic circuit in a disk-type permanent magnetic micro-generator is proposed, including modeling, theoretical analysis, simulation and experiment. The effects of the structural parameters on magnetic flux density in the magnetic gap and the constraint relations among the parameters are discussed. The calculation method of magnetic flux density in magnetic gap and the optimization scheme of structural parameters of micro-generator are studied. The design method of magnetic circuit in the planar permanent magnetic micro-generator is summarized. Errors between the theoretical calculations and experimental results are less than 7%, which verifies the rationality and accuracy of the calculation method of magnetic flux density. |
