摘要
选择内转子直驱永磁的电机系统结构进行风力发电机设计。采用等效磁路的方法进行了初步设计。使用有限元方法分析了电机在空载、额定负载和三相短路情况下的工作特性。结果表明电机齿槽转矩小、工作点合理,且短路状态下不会发生永磁材料的永久去磁。
Inner-rotor direct-coupled structure is adopted in wind generator design. Pre-design of the generator is carded out with equivalent magnet circuit method. The generator characteristics in the states of no load, rated load and short circuit are analyzed with finite element method. The result shows that the cogging torque is small and working points are reasonable, and irreversible demagnetization will not happen in short circuit state.
