Summary:PROBLEM TO BE SOLVED: To provide a rotor manufacturing method that can reduce the amount of cull being a residual cured material of a resin.SOLUTION: In the rotor manufacturing method, two rotor cores 20 in which a permanent magnet 40 is arranged in a magnet insertion hole 14 are oppositely arranged while sandwiching an intermediate mold 110 in a rotor-core arrangement step S210, and a gap between the magnet insertion hole 14 and the permanent magnet 40 is filled with a resin by supplying the resin from the intermediate mold 110 to the two rotor cores 20 in a resin filling step S230.SELECTED DRAWING: Figure 2 【課題】樹脂の残留硬化物であるカル量の低減を図ることができるロータ製造方法を提供する。【解決手段】ロータ製造方法において、ロータコア配置工程Ｓ２１０で磁石挿入孔１４に永久磁石４０が配置された２つのロータコア２０を中型１１０を挟んで対向配置し、樹脂充填工程Ｓ２３０で中型１１０から２つのロータコア２０に樹脂を供給して、磁石挿入孔１４と永久磁石４０との間に樹脂を充填する。【選択図】図２
