本文提出了一种新的概念，其中交流绕组和永磁体（PMs）都放置在定子的发电机。采用具有特殊图案的集中绕组和放置在单独槽中的相位线圈。永磁体位于轮辐式磁场集中装置中，可提供高通量强化，并可使用较低剩磁和能量的非稀土磁体。转子位于定子外部，具有简单而坚固的磁阻型配置，无需任何有源电磁激励部件。工作原理的基础上介绍了封闭形式的分析气隙磁通密度分布的虚功的概念。采用电磁有限元法对一台采用不同剩磁和比能永磁体的3 MW直驱式风力涡轮机进行了初步设计和参数化设计研究。结果包括指标的良好的激励和良好的电机设计;损失;和效率的估计，表明性能相媲美的PM同步设计采用昂贵的和关键的供应稀土PM可以实现与非稀土PM使用建议的配置。
This paper proposes a novel concept for an electric generator in which both ac windings and permanent magnets (PMs) are placed in the stator. Concentrated windings with a special pattern and phase coils placed in separate slots are employed. The PMs are positioned in a spoke-type field concentrating arrangement, which provides high flux intensification and enables the use of lower remanence and energy non-rare earth magnets. The rotor is exterior to the stator and has a simple and robust reluctance-type configuration without any active electromagnetic excitation components. The principle of operation is introduced based on the concept of virtual work with closed-form analytical airgap flux density distributions. Initial and parametric design studies were performed using electromagnetic FEA for a 3MW direct-drive wind turbine generator employing PMs of different magnetic remanence and specific energy. Results include indices for the goodness of excitation and the goodness of the electric machine designs; loss; and efficiency estimations, indicating that performance comparable to PM synchronous designs employing expensive and critical supply rare-earth PMs may be achieved with non-rare earth PMs using the proposed configuration.
