축 자속형 영구자석 기기의 자화패턴에 따른 성능 특성 = Performance Characteristic of Axial Flux Machine according to Magnetizing Pattern

다국어 초록 (Multilingual Abstract)

The axial flux machine has higher power density than conventional radial flux machine, so it is widely applied to various industrial area, for instance, low speed wind power generator. This paper deals with the performance characteristic of axial flux machine according to magnetizing pattern. For the conventional radial flux machine, 2D finite element method (FEM) is generally applied, but axial flux machine has to employ 3D FEM with long analysis time due to its own structural characteristic. This paper introduces the analytical method to analyze its characteristic to overcome the disadvantage of 3D FEM, and performs the comparative analysis on two types of magnetizing patterns, which are vertical and Halbach patterns.
