摘　　要：为满足风力发电系统对发电机提出的低转速要求,研究设计了两台不同类型的轴向磁通永磁同步发电机。分析了这两种发电机拓扑结构的不同特点,确定了永磁极的形状和极弧系数,讨论了发电机的极槽配合问题,并着重对发电机的永磁体和绕组参数进行了详细计算。采用一种准三维有限元方法对两台发电机进行了仿真计算,计算结果验证了设计方法的可靠性,最后利用有限元计算结果对这两种类型发电机的电磁特性进行了比较分析。In order to satisfy the low speed requirement of wind power generation system,two different types of axial flux permanent magnet machines were designed in this paper.The paper analyzed the different characteristics of these two kinds of topological structure,the shape of the permanent magnet poles and pole-arc coefficients were determined,the generators of slot-pole coordination problem was discussed,and the parameters of the permanent magnets and windings were calculated in detail in this paper.The paper computed the models with the quasi-3 Dfinite element analysis（FEA）methodology for both generators,the reliability of designed methodology applied in axial flux permanent magnet machine was proved by finite element analysis（FEA）results.At last,the electromagnetic characteristics of these two types of generators were compared by Finite Element Analysis（FEA）results.
