Characteristic analysis and experiment of axial flux type permanent magnet synchronous generator for small wind turbine

소형풍력발전 시스템용 축방향 자속형 영구자석 동기발전기의 특성해석과 실험

This paper presents a axial flux permanent magnet synchronous generator(AFPMSG), which is suitable for both vertical-axis and horizontal-axis wind turbine generation system. The design and construction features of the AFPMSG are reviewed. The characteristic analysis is performed such as cogging torque and e.m.f waveform, with the aid of a 3D finite element method. The experimental results confirm the characteristic analysis developed.
