<P>PROBLEM TO BE SOLVED: To provide a laminated iron core manufacturing method which closes magnet insertion holes, respectively having openings at parts thereof, and thereby resin-sealing permanent magnets without requiring special closing members. <P>SOLUTION: A laminate iron core body 10a is formed by laminating multiple iron core pieces 11 and has magnet insertion holes 13, 14 respectively including openings 17, 18 which open at an inner space 15 or the outer side. In a laminate iron core manufacturing method, permanent magnets 20, 21 are respectively inserted into the magnet insertion holes 13, 14 of the laminated iron core body 10a and the permanent magnets 20, 21 are resin sealed in the magnet insertion holes 13, 14 with the opening 17, 18 closed by closing members 23. A closing piece member 32 forming each closing member 23 is tentatively connected to each iron core piece 11, and the closing member 23 is removed with the laminate iron core body 10a resin sealed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
