摘要
研究采用深槽结构对面贴式永磁同步电机的弱磁调速性能的影响。首先建立深槽面贴式永磁同步电机磁路模型。然后对该电机进行方案优选,通过有限元方法计算,分析深槽面贴式永磁同步电机的弱磁扩速情况。最后通过响应曲面法将满载效率及弱磁扩速倍数作为优化目标进行深槽面贴式永磁同步电机的优化,获得最佳方案。有限元分析结果验证该方法的有效性。
Used deep-slot structure to study the influence of the weak magnetic speed regulating performance of permanent magnet synchronous motors. Firstly, analytical model of a deep-slot surface-mounted permanent magnet synchronous motor was built that based on the magnetic circuit model , then selected the optimal solution. The ideal motor program was brought in the finite element method to calculate, analyzed the field weakening expanded speed situation for a deep-slot surface-mounted permanent magnet synchronous motor. Finally, response surface methodology to optimize a deep-slot surface-mounted permanent magnet synchronous motor which made full load efficiency and weak magnetic speed ratio as the optimization goals, and got the best solution, inite element analysis results show the effectiveness of the method.
