Zusammenfassung:To improve precision of a rotor to be manufactured.SOLUTION: In joining step S1, a bottom face 12 of a first shaft body 11A is joined to a bottom face 2 of a magnet 1A, and a bottom face 22 of a second shaft body 21A is joined to a bottom face 3 of the magnet 1A. In first processing step S2, respective side faces 6, 16 and 26 of the mutually joined magnet 1A, the first shaft body 11A and the second shaft body 21A are processed so that the respective side faces 6, 16 and 26 of the magnet 1A, the first shaft body 11A and the second shaft body 21A form side faces of the same cylinder. In fitting step S3, an armor ring 51 is fitted to the magnet 1A, the first shaft body 11A and the second shaft body 21A with the respective side faces 6, 16 and 26 processed. In second processing step S4, the side faces 16 and 26 of the first shaft body 11A and the second shaft body 21A, which are exposed from the armor ring 51 of the magnet 1A, the first shaft body 11A and the second shaft body 21A, to which the armor ring 51 is fitted, are processed with an outer peripheral face 53 of the armor ring 51 as a reference.SELECTED DRAWING: Figure 4 【課題】製造されるロータの精度を向上させる。【解決手段】接合工程S1では、磁石1Aの底面2に第1軸体11Aの底面12が接合され、磁石1Aの底面3に第2軸体21Aの底面22が接合される。第1加工工程S2では、磁石1A、第1軸体11A及び第2軸体21Aのそれぞれの側面6,16,26が同一の円柱の側面をなすように、互いに接合された磁石1A、第1軸体11A及び第2軸体21Aのそれぞれの側面6,16,26が加工される。嵌合工程S3では、それぞれの側面6,16,26を加工された磁石1A、第1軸体11A及び第2軸体21Aにアーマリング51が嵌合させられる。第2加工工程S4では、アーマリング51の外周面53を基準として、アーマリング51を嵌合させられた磁石1A、第1軸体11A及び第2軸体21Aのアーマリング51から露出した第1軸体11A及び第2軸体21Aの側面16,26が加工される。【選択図】図4
