Characteristic analysis and comparison of axial flux machines according to magnetization pattern for 500 W-class wind power generator application

Abstract

This paper presents the electromagnetic characteristic analysis of axial flux machines applied to 500(W) class wind power generators. For the dramatic analysis time reduction, analytical method is applied, and comparative analysis is performed according to magnetization patterns of permanent magnets. Due to their structural features, quasi 3-dimensional analysis is employed, and correction function is introduced to consider the flux leakage of the machines. The analysis results are compared with the results by finite element method and experiment to validate the suggested method performed in this paper showing high reliability. ？ 2012 American Institute of Physics.
