摘要： An electric machine comprising a stator and a rotor (2) separated by an air gap (12), (a) the rotor (2) being composed with permanent magnets (8) magnetized substantially in circumferential direction, and with one magnetic flux conducting piece assembly (10) of at least one magnetic flux conducting piece (10a; 10b) between two adjacent permanent magnets each; (b) the permanent magnets (8)—when looking at the overall geometry—each having an increasing circumferential width from the head portion on the side of the air gap to the foot portion; (c) and the conducting piece assemblies (10) between two adjacent permanent magnets (8)—when looking at the overall geometry—each having a decreasing circumferential width from the head portion on the side of the air gap to the foot portion, characterized in (d) that the conducting pieces (10a; 10b) at the foot end each have a widened portion in circumferential direction, having at least one shoulder (20) through which they are supported on an adjacent permanent magnet (8) against displacement in the direction towards the air gap (12).
摘要翻译：一种电机，包括定子和由气隙（12）分开的转子（2），（a）转子（2）由大致周向磁化的永磁体（8）组成，并具有一个磁通导电片在两个相邻的永磁体之间的至少一个磁通导体片（10a; 10b）的组件（10）;（b）永磁体（8） - 当看到总体几何形状时，每个具有从头部起增大的周向宽度（c）和两个相邻的永磁体（8）之间的导电片组件（10） - 当从整体几何形状看，每个具有从头部的周向宽度减小时在所述气隙的与所述脚部的一侧上，其特征在于，（d）所述脚端处的导电片（10a; 10b）在圆周方向上具有加宽部分，其具有至少一个肩部（20），通过所述肩部在相邻的支持永磁体（8）在朝向空气间隙（12）的方向上移动。
