Abstract: A core of a rotating electrical machine is formed by laminating core plates, which are each formed by a plurality of core pieces. According to the method for manufacturing the core, a belt-like workpiece is first conveyed intermittently in its longitudinal direction. Then, while the workpiece is in a stopped state, side edges of a core piece are punched out. At a downstream position in the conveying direction of the workpiece, the remaining edges of the core piece are cut, so that the core piece is punched out. The punched out core pieces are lined up on a support. The core plate is thus formed, and the core pieces are laminated.

Abstract: 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.
