本文将磁通助记法的概念新推广到风力发电机中。通过在外转子双凸极铝镍钴永磁电机中加入一个小型磁化绕组，提出并实现了一种新型磁通助记永磁无刷风力发电机。这种发电机可以提供有效和高效的气隙磁通控制。首先，采用有限元方法对该发电机的特性进行了分析。其次，设计闭环磁链控制，实现时变风速下的恒电压输出。最后给出了实验结果，验证了所提出的发电机和控制系统的有效性。
In this paper, the concept of flux mnemonics is newly extended to the wind power generator. By incorporating a small magnetizing winding into an outer-rotor doubly salient AlNiCo permanent magnet (PM) machine, a new flux-mnemonic PM brushless wind power generator is proposed and implemented. This generator can offer effective and efficient air-gap flux control. First, the characteristics of the proposed generator are analyzed by using the finite element method. Second, the closed-loop flux control is devised to achieve a constant generated voltage under time-varying wind speeds. Finally, the experimental results are given to verify the validity of the proposed generator and control system.
