提出了一种新型永磁无刷风力发电机。该电机采用外转子拓扑结构，旨在直接捕获风力。为了实现高功率密度，将高速永磁无刷发电机与同轴磁齿轮巧妙地集成在一起。详细阐述了设计细节，重点阐述了风力发电的特殊约束条件。采用时步有限元法，模拟了系统的静态特性以及空载和带载运行情况。还建立了一个原型用于实验。仿真和实验结果验证了新型DSPM设计方法的有效性.最后，通过定量比较，证明了该机器具有体积小、重量轻、成本低等优点。
This paper presents a new permanent-magnet (PM) brushless machine for wind power generation. This machine adopts an outer-rotor topology, aiming at capturing wind power directly. In order to achieve high power density, a high-speed PM brushless generator is artfully integrated with a coaxial magnetic gear. The design details, with emphasis on the special constraints of wind power generation, are elaborated. By using the time-stepping finite element method, the static characteristics as well as no-load and on-load operations are simulated. A prototype is also built for experimentation. Both simulation and experimental results are given to verify the validity of the proposed machine. Finally, a quantitative comparison is made to justify that the proposed machine is of smaller size, lighter weight, and lower cost than its counterparts.
