摘要： A method for manufacturing a laminated iron core is provided. A laminated iron core body including a permanent magnet inserted into a magnet-insert hole is arranged between a molding die and a holding die. A cull plate is arranged between the molding die and the laminated iron core body. The cull plate has a groove shaped runner directed toward the magnet-insert hole from a resin reservoir and provided with a gate hole communicating with the magnet-insert hole, and a through hole which vertically passes through the cull plate is formed in the runner of the cull plate at a different position from a position of the gate hole. After the magnet-insert hole is filled with the mold resin a resin residue remaining in the cull plate is pushed off and removed from the gate hole and the through hole.

摘要： 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.
摘要翻译：层叠铁心的树脂密封方法包括以下步骤：通过将芯体11夹在树脂注射模具20和支撑模具21之间来夹持; 使用柱塞37从设置在树脂注射模具20中的树脂储存罐24挤出熔融树脂; 并且将永磁体18树脂密封在磁体插入孔16和17中，其中树脂注射模具20的树脂储存罐24的材料和树脂从树脂储存罐24通过的区域是超硬材料并且由于树脂的流动而导致树脂注射模具20中的磨损降低。由此，由于热膨胀差异，树脂储存罐24和树脂注射模具20之间的间隙不容易产生。

摘要： The anisotropic rare earth magnet powder of the present invention includes powder particles having R2TM14B1-type crystals of a tetragonal compound of a rare earth element (R), boron (B), and a transition element (TM) having an average crystal grain diameter of 0.05 to 1 μm, and enveloping layers containing at least a rare earth element (R′) and copper (Cu) and enveloping surfaces of the crystals. Owing to the presence of the enveloping layers, coercivity of the anisotropic rare earth magnet powder can be remarkably enhanced without using a scarce element such as Ga and Dy.
