Abstract

A method of manufacturing a laminated core includes: preheating a rotor core body; attaching a cull plate onto a surface of the body removed from a preheating device; placing the body in a resin-sealing mold; heating and liquefying resin in resin reservoir pots by the mold; extruding the liquefied resin into plural magnet insertion holes and curing the resin; and ejecting a laminated rotor core from the mold and detaching the plate, wherein attaching the plate and detaching the plate are performed at a same station, and the plate detached is used as the plate at the attaching of the cull plate.
