    • Disclosed are a rotor of a line start permanent magnet motor and a manufacturing method thereof. The rotor comprises: a core provided with an axial hole for inserting an shaft and a plurality of penetrated magnet coupling holes formed at a periphery of the axial hole; permanent magnets respectively coupled to the magnet coupling holes of the core; a third end ring provided with magnet paths for respectively passing the permanent magnets and coupled to one side surface of the core; a fourth end ring having the same appearance as the third end ring and coupled to another side surface of the core to be connected with the third end ring; a magnet supporting plate positioned between one side surface of the core and the fourth end ring for preventing the permanent magnets from being separated; and a fixing member inserted into the magnet paths of the third end ring for preventing the permanent magnets from being separated. Accordingly, the structure and the manufacturing process are simplified thus to improve a synchronization performance, thereby enhancing efficiency of the line start permanent magnet motor, reducing a manufacturing cost, and enhancing an assembly productivity.
    • 公开了一种线路启动永磁电动机的转子及其制造方法。 转子包括:芯,其设置有用于插入轴的轴向孔和形成在轴向孔的周边处的多个穿透的磁体联接孔; 分别耦合到芯的磁体耦合孔的永磁体; 第三端环设置有用于分别通过永磁体并耦合到芯的一个侧表面的磁路; 第四端环具有与第三端环相同的外观并且耦合到与第三端环连接的芯的另一侧表面; 定位在所述芯的一个侧表面和所述第四端环之间的用于防止所述永磁体分离的磁体支撑板; 以及插入到第三端环的磁路中的固定构件,用于防止永磁体分离。 因此,简化了结构和制造过程,从而提高同步性能,从而提高线路起动永磁电动机的效率,降低制造成本,提高组装生产率。
