中文摘要：

横向磁通永磁电机以电负荷和磁负荷在空间上相互解耦，能获得较高的功率密度而闻名。因其同时具有低速、大转矩及多极数的优点而适用于直驱风力发电系统。与传统横向磁通永磁发电机相比，该文提出的新型双C型定子聚磁式转子的横向磁通永磁发电机空间利用率得到明显提高。对发电机的基本结构和运行原理作了详细的描述。为了验证双C型结构在原理上的可行性，采用三维有限元分析计算了空载磁场分布，对其静态特性和瞬态特性包括磁通密度、电枢反电势，以及电枢自感波形进行了研究，对发电机的齿槽转矩也进行了分析。结果表明，双C型定子结构可以显著提高横向磁通永磁发电机的功率密度。最后设计研制了一台三相1kW样机，并进行了实验，实验结果与理论分析基本一致。

英文摘要：

Transverse flux permanent magnet generator is well-known for the decoupled electric load and magnetic load to harvest high power density. It is applied in direct-drive wind power generation for the merits of low speed, large torque capability and considerable pole numbers. This paper presents a novel transverse flux permanent magnet generator with double-C stator and flux-concentrated rotor （DSFC-TFPMG）, which has almost twice the flux linkage compared with traditional double-side TFPMGs. The structure and operation principle of the generator were described in detail. The three-dimensional （3D） finite element method （FEM） was employed to compute the no-load magnetic field distributions. Static characteristics, including flux density waveform, EMF waveform and inductance waveform of the armature winding, were obtained to verify the principle and feasibility of the generator with double-C stator hoops. The cogging torque of the presented generator was also analyzed and verified by the 3D FEM. The FEM results show that the generator has significantly increased power density due to the double-C stator structure. A prototype is fabricated and some experiments are conducted, which results verify the analysis preview well.
