    • A method of manufacturing a laminated rotor core, includes a first process of placing segment dummy plates between an iron core and a die, each of each segment dummy plates covering one or more of plural magnet insertion portions and including a resin injection hole communicating to the one or more of the magnet insertion portions; a second process of injecting a resin from resin reservoir parts formed in any one of an upper die and a lower die holding the iron core through the resin injection hole of each segment dummy plate to the corresponding one or more of the magnet insertion portions; and a third process of detaching the segment dummy plates together with excess resin after the resin injected to the one or more of the magnet insertion portions is cured.
    • 一种叠层转子铁芯的制造方法,其特征在于,包括:在铁芯和模具之间配置分段虚拟板的第一工序,各个虚拟板各自覆盖多个磁体插入部的一个或多个, 一个或多个磁体插入部分; 将形成在保持铁芯的上模和下模中的任一个中的树脂储存部分注入树脂的第二过程通过每个段虚拟板的树脂注入孔到相应的一个或多个磁体插入部分; 以及在注入到所述一个或多个所述磁体插入部分中的树脂被固化之后,将多个模板与多余的树脂一起分离的第三过程。
