摘　　要：盘式永磁发电机的磁通为轴向,其磁路与传统电机相比具有很大不同。介绍了分布式系统用盘式永磁发电机的结构特点并推导了其基本的电磁关系;通过经验及计算分析确定了电机的各尺寸和永磁体材料,利用Ansoft Maxwell 3D软件对电机的静态和瞬态磁场进行了仿真计算并对其磁场分布、电磁力、磁链等进行了分析。结果与设计相符,同时为改善风力发电机系统参数提供了理论依据,方便了电机的优化设计,可以有效降低研发成本,提高设计精度。The flux of the disc permanent magnet generator is axial, and its magnetic circuit is very different from the traditional motor. The structure characteristics of disc permanent magnet generator for distributed system applications were introduced, and the basic electromagnetic relationship was deduced, the size of the motor and the permanent magnet material had been determined through empirical calculation and analysis, the static and transient magnetic field of the motor was simulated and calculated by the Ansoft Maxwell 3D and the magnetic field distribution, electromagnetic force and flux linkage were analyzed. The results were consistent with the design as well as provide the theoretical basis to improve the parameters of wind turbine system and reduce its development costs, increasing its design accuracy.
