Abstract
本发明属于容错电机技术领域，具体公开一种永磁容错电机，包括定子、转子和扼流环，定子包括沿周向均匀分布的多个定子齿和定子绕组，定子齿为离散结构，相邻定子齿间的夹角为360° / X，X为单相定子齿数量，定子绕组采用轴向分布方式嵌入定子齿的槽中；转子位于定子内侧，包括转子铁芯和磁钢，磁钢为表贴式永磁体，两个极性相反的磁钢组成一对磁极，每一对磁极中的两个磁钢沿轴向排列，且与定子齿对齐；扼流环轴向分布于相邻定子齿之间，扼流环为矩形环结构，单个扼流环构成一个容错单元。本发明永磁容错电机在匝间或单相短路时，抑流环无延时产生高阻抗漏感，抑制短路电流，提高了电机的容错性，无需故障检测，可靠性高。
