Abstract: A method of manufacturing a stacked core includes: forming a stack by stacking a plurality of core members, each of the plurality of core members including one or more blanked members blanked by a die from a metal plate along a predetermined shape; removing one core member of the plurality of core members from the stack; supplying adhesive to the one core member removed from the stack; and stacking the one core member next to an adjacent core member of the plurality of core members so that the adhesive is placed between the one core member and the adjacent core member.

Abstract: A separation apparatus for a laminated core is configured to separate an annular laminated core, which includes a plurality of core pieces each of which includes a yoke portion and a tooth portion extending from the yoke portion in a direction intersecting the yoke portion and is integrated by the temporary connection of the adjacent core pieces at end portions of the yoke portions, into the respective core pieces. The separation apparatus includes a plurality of separation members that are movable in a radial direction of the laminated core and are disposed so as to be arranged in a circumferential direction of the laminated core, and an actuator that is configured to apply an outward force in the radial direction to the laminated core through the respective separation members by moving the respective separation members outward in the radial direction.

Abstract: A stator core comprises a stack and a resin portion. The stack comprises an annular yoke portion, a plurality of tooth portions, and a plurality of slots. The resin portion covers an inner wall surface of a slot of the plurality of slots. The resin portion protrudes outward relative to an end surface of the stack in a height direction of the stack. The resin portion is formed on at least a part of an end surface of the tooth portion so as to extend from the inner wall surface of the slot around the end surface of the tooth portion. A resin end portion of the resin portion is disposed on the end surface of the stack and a corner of the resin end portion is formed as an inclined surface including a planar surface or curved surface.
