ROTOR MANUFACTURING METHOD FOR ROTARY ELECTRIC MACHINE

To reduce or eliminate wraparound of a material for a bond magnet to a flux barrier part while preferably improving workability according to an insertion of a non-magnetic body into a magnet hole.SOLUTION: The present invention discloses a rotor manufacturing method for a rotary electric machine, including: a step of preparing a workpiece of a rotor core for a rotary electric machine having a magnet hole; an insertion step of inserting a non-magnetic body into one part of magnet hole; a heating step of heating the workpiece before the insertion step or after the insertion step; and a filling step of filling a material for a bond magnet of which a magnet powder and a binding material are mixed into a part adjacent to the non-magnetic body in the magnet hole after a cooling after the heating step or subsequent to the heating step.SELECTED DRAWING: Figure 5 【課題】磁石孔内への非磁性体の挿入に係る作業性を良好化しつつ、フラックスバリア部へのボンド磁石用の材料の回り込みを低減又は無くす。【解決手段】磁石孔を有する回転電機用ロータコアのワークを準備する工程と、磁石孔内の一部に、非磁性体を挿入する挿入工程と、挿入工程の前に又は挿入工程の後に、ワークを加熱する加熱工程と、加熱工程の後の冷却後に又は加熱工程に後続して、磁石孔内の非磁性体に隣接する部分に、磁石粉末と結合材とを混合したボンド磁石用の材料を充填する充填工程とを含む、回転電機用ロータ製造方法が開示される。【選択図】図５
