Method of manufacturing laminated core

This disclosure relates to a method of manufacturing a laminated core including a plurality of poles arranged side by side in a circumferential direction, each pole having three or more magnet housing holes and magnets housed in the magnet housing holes. The manufacturing method includes: a step of preparing a lamination having the magnet housing holes; a step of injecting sealing resin into a pair of magnet housing holes arranged at symmetric positions with respect to a line extending in a radial direction of the lamination, with the magnets being disposed in the pair of respective magnet housing holes; and a step of injecting sealing resin into another magnet housing hole, with the magnet being disposed in the magnet housing hole. 本发明提供种层叠铁芯的制造方法，其是多个极以在周向上排列的方式设置且各个极具有三个以上的磁体收容孔及在这些孔内收容的磁体的层叠铁芯的制造方法。该制造方法包含：准备具有磁体收容孔的层叠体的工序；在以沿层叠体的径向延伸的直线为基准设置在对称位置上的对磁体收容孔中分别配置有磁体的状态下，向这些孔注入封固用树脂的工序；在其它磁体收容孔中配置有磁体的状态下，向该孔注入封固用树脂的工序。
