摘要(Abstract):
针对传统磁性复合材料轴向间隙电机在高转速大力矩工况下存在工作效率不高的问题,提出了一种采用粘结钕铁硼永磁体的新型轴向间隙电机。首先,所提轴向间隙电机具有扁平形状结构,并采用了10极12槽的分数槽结构。其次,为了抑制涡流损耗且降低成本,无芯转子结构采用了表面永磁配置,其中粘结钕铁硼永磁体被嵌入非磁性的支架中。定子结构采用了基于软磁复合材料的紧凑型铁芯。定子分为6段,每个分段具有2个定子铁芯,共12个定子铁芯。最后,通过三维有限元仿真和样机测试,验证了所提电机的有效性,并与采用烧结钕铁硼永磁体和铁氧体永磁体的轴向间隙电机进行了比较。研究结果表明,在高转速大力矩工况(6000 r/min,1.27 Nm)下,粘结钕铁硼永磁体能够更大幅提升轴向间隙电机的工作效率,最高达到93.2%。所提高性能电机在紧凑的中小型工业水泵中在具有较高的应用前景。
