    • A method comprising: a first process of placing a laminated rotor core (13) in a preheating device (18) to preheat the laminated core (13); a second process of removing the preheated laminated core (13) from the preheating device (18) and disposing the laminated core (13) between upper and lower dies (14, 15) of a resin sealing apparatus (29); a third process of pressing the laminated core (13) by the upper and lower dies (14, 15) and liquefying resin material (17) in resin reservoir pots (16) by heating; and a fourth process of ejecting the liquefied resin material (17) from the pots (16) into the magnet insertion holes (12) by plungers (32) inserted and moving vertically in the pots (16) and thermally curing the resin material (17). The method improves efficiency of resin sealing the permanent magnets (11) in the laminated core (13).
    • 一种方法,包括:将叠层转子芯(13)放置在预热装置(18)中以预热叠层铁芯(13)的第一工序; 从所述预热装置(18)中取出预热的叠层铁芯(13)并将所述层叠铁芯(13)设置在树脂密封装置(29)的上下模具(14,15)之间的第二工序; 通过上模和下模(14,15)挤压层压芯(13)并通过加热液化树脂储存罐(16)中的液化树脂材料(17)的第三过程; 以及通过在罐(16)中垂直插入并移动并使树脂材料(17)热固化的柱塞(32)将液化树脂材料(17)从罐(16)喷射到磁体插入孔(12)中的第四工序 )。 该方法提高了层叠铁心(13)中的永磁体(11)的树脂密封效率。
