摘　　要：无铁心轴向磁通永磁发电机具有起动转矩低,效率高,结构紧凑等优点,非常适用于低风速条件下发电。本文对一种无铁心轴向磁通永磁风力发电机的原理和电磁参数进行了分析和推导,建立起发电机有限元分析模型,首先分析了瞬态条件下电机气隙磁场磁场分布规律,进而分析了发电机各部件运动受力特点,最后分析了空载和带载条件下发电机瞬态输出特性。Air-cored axial flux permanent magnet generators （AFPMG）, which have start with a low torque high efficiency and compact structure advantages, are most suitable for wind power generation at low wind speed. This paper analysed air-cored axial flux permanent magnet wind generators operate principle and derivate the electromagnetic parameter, three-dimensional （3D） FEA models were built to verify the analytical model, the distribution of air-gap filed was analyzed firstly, and then the stressing features for motion components, Finally, analysed the generator transient output characteristics at no-load and load conditions.
