Abstract
A method of resin-sealing for a laminated core includes the steps of: holding by sandwiching a core bodybetween a resin injection moldand a supporting mold; extruding a molten resin using a plungerfrom a resin reservoir potprovided in the resin injection mold; and resin-sealing the permanent magnetsin the magnet insertion holesand, wherein a material of the resin reservoir potof the resin injection moldand a region through which the resin passes from the resin reservoir potis a superhard material, and wear in the resin injection molddue to a flow of the resin is reduced. With this, a gap between the resin reservoir potand the resin injection molddue to a difference in thermal expansion is less easily produced.
