    • A motor includes a stator formed of a stator iron-core having salient pole iron-cores and windings, and a rotor having a rotor iron-core in which permanent magnets are buried. A magnetic pole centerline connecting a rotary center of the rotor to a magnetic pole center crosses an external shape of the rotor iron-core at end point X, and the magnetic-pole boundary line connecting the rotary center to a magnetic pole boundary point crosses the external shape of the rotor iron-core at end point Z. A straight line angled at a given angle θa from the magnetic pole centerline has end point A. Then a sectional view of the rotor iron-core shows an arc drawn between the end points X and A, and the arc's center is the rotary center. The end points A and Z are connected by one or more than one straight lines in series.
    • 电动机包括由具有凸极铁芯和绕组的定子铁芯形成的定子和具有永磁体的转子铁心的转子。 将转子的旋转中心与磁极中心连接的磁极中心线在端点X与转子铁芯的外形交叉,将旋转中心与磁极边界点连接的磁极边界线穿过 在端点Z处的转子铁芯的外部形状。以给定角度和角度成角度的直线;来自磁极中心线的a具有端点A.然后转子铁芯的截面图示出了在 终点X和A,弧的中心是旋转中心。 端点A和Z通过串联的一条或多条直线连接。
