摘要： A method for manufacturing a laminated iron core includes providing a plurality of annular iron core piece rows, each of which is configured by annularly arranging a plurality of divided iron core pieces including yokes and teeth, and the yokes of the annularly-adjacent divided iron core pieces in the annular iron core piece row are mutually different in shape. In the method, the annular iron core piece rows are laminated by changing a rotational angle of the newly laminated annular iron core piece row relatively to the lastly laminated annular iron core piece row laminated so that the divided iron core piece with a shape different from that of the divided iron core piece is laminated on the lastly laminated divided iron core piece.

摘要： In a method of manufacturing a laminated core, a laminated core body 14 including magnet insertion holes 12 and 13 with magnet pieces 15 inserted therein is placed between a molding (upper) die 10 and a retaining (lower) die 11, and a molding resin 19 is filled from resin reservoir portions (pots) 16 to fix the pieces 15 in the holes 12 and 13. Between the die 10 and the body 14, a guide member 18 is placed, which includes resin passages 31 provided from the portions 16 to the holes 12 and 13 and gates 30 connecting to the holes 12 and 13 on downstream sides of the passages 31. The method can reduce lead time of a production line without replacing the molding dies for different laminated rotor cores and thus without preparing different types of molding dies.

摘要： There is provided a method for measuring a laminated iron core. The method includes preparing a laminated iron core in which two or more kinds of metal plates with different shapes are laminated and a deformed part is formed inside a hole continuing in a lamination direction of the laminated iron core, acquiring a surface profile data indicating a surface shape of the deformed part through an inlet of the hole by a non-contact sensor located in an outside of the hole, and calculating a size of the deformed part by a calculator based on the surface profile data.

摘要： A method of resin-sealing for a laminated core includes the steps of: holding by sandwiching a core body 11 between a resin injection mold 20 and a supporting mold 21; extruding a molten resin using a plunger 37 from a resin reservoir pot 24 provided in the resin injection mold 20; and resin-sealing the permanent magnets 18 in the magnet insertion holes 16 and 17, wherein a material of the resin reservoir pot 24 of the resin injection mold 20 and a region through which the resin passes from the resin reservoir pot 24 is a superhard material, and wear in the resin injection mold 20 due to a flow of the resin is reduced. With this, a gap between the resin reservoir pot 24 and the resin injection mold 20 due to a difference in thermal expansion is less easily produced.
