Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing a laminated core comprising: a first step of placing and preheating a rotor core body in a preheating device, the rotor core body being formed by laminating plural core sheets and being provided with plural magnet insertion holes inserted with permanent magnets; a second step of attaching a cull plate onto a surface of the rotor core body ejected from the preheating device; a third step of placing the rotor core body attac…
