The manufacturing method of a motor core includes attaching an ID code to a stack of blanked members in which a magnet insertion hole to fill with a resin material is formed, the ID code containing information in accordance with a type of the stack, reading the information from the ID code which is attached to the stack, and setting a mold condition based on the information read from the ID code. The mold condition includes at least one type of condition including: the resin material to be injected to the magnet insertion hole, an injection amount of the resin material, and a discharge position of the resin material. A mold device is controlled to inject the resin material to the magnet insertion hole in accordance with the mold condition.

Manufacturing method of stacked core

An apparatus for inserting a magnet into a rotor iron core includes a magnet inserting unit configured to insert a permanent magnet into a magnet-insert hole formed along a lamination direction of a rotor iron core body in which a plurality of iron core pieces are laminated, and a guide member to be attached to the magnet inserting unit, and arranged in a space formed between the magnet inserting unit and the rotor iron core body and configured to communicate the magnet-insert hole of the rotor iron core body to a supply part for the permanent magnet formed in the magnet inserting unit.

Apparatus for inserting magnet into rotor iron core

A method for manufacturing a laminate used for manufacturing a rotor is provided. The method includes: (a) stamping out a plurality of workpieces from a metal sheet wherein each of the workpieces has a temporarily-interlocking portion; and (b) obtaining a laminate including the workpieces integrated together by the temporarily-interlocking portion, wherein each of the workpieces further has a shaft hole, a magnet insertion hole, and a weight-reducing hole formed between the shaft hole and the magnet insertion hole, and the temporarily-interlocking portion is provided to the weight-reducing hole.

Method for manufacturing a laminate and method for manufacturing a rotor

This disclosure relates to a method for manufacturing a laminate used for manufacturing a laminated core including a circumferential yoke part and a plurality of magnetic pole parts radially extending from the yoke part. This method includes: feeding a metal sheet drawn from a roll thereof to a progressive die; stamping out a plurality of workpieces from the metal sheet in the progressive die, wherein each of the workpiece comprises a temporarily-interlocking portion between adjacent magnetic pole portions; and stacking the workpieces to integrate these workpieces together by the temporarily-interlocking portion to obtain the laminate.

Laminate and method for manufacturing the same and method for manufacturing laminated core

A method for manufacturing a laminated rotor core comprises a first step of positioning and mounting a laminated core bodyon a mounting tableof a carrying tray, a second step of positioning and arranging the laminated core bodymounted on a mounting tableon a lower die, the laminated core bodyhaving permanent magnetsinserted into respective magnet insertion holesand, and clamping the laminated core bodymounted on the mounting tableby an upper dieand a lower die, and a third step of pushing resin out of resin reservoir potsprovided in the lower dieand filling the respective corresponding magnet insertion holesandof the laminated core bodywith the resin through resin passagesformed in the mounting table

Method for manufacturing laminated rotor core

A method of resin-sealing a laminated core, including inserting permanent magnetsinto magnet insertion holesof a core body, pressing the bodywith upper and lower dies, and injecting resinto the holesfrom a resin reservoirof the dieorvia a runnerin a removable cull plate, one end of the runnerhaving plural resin injection holesper hole. The resinpresses the magnetsin the holesto one sides in a radial direction of the holes. Thereby, resin-sealing is performed using the plateand the magnetsare arranged in radially outward or inward sides even with narrow gaps between the magnetsand the holesor without resin injection holes in centers in a width direction of the holes

Method of resin-sealing laminated core

A rotor having permanent magnetsincludes: a laminated core bodyhaving a shaft holein the center thereof and magnet insertion holesaround the shaft holepermanent magnetsdisposed in the respective magnet insertion holesand first and second end face platesdisposed on one axial end and the other axial end of the laminated core bodyrespectively, the first and second end face platesincluding first and second through holesrespectively. The first and second through holeseach overlap a contour of a magnet insertion holeon a radially inner side or a radially outer side in a plan view, and have first and second tapered portionsgradually expanding the diameter toward the magnet insertion holerespectively.
