    Abstract: The rotor includes a drive shaft, a first rotor core unit, and a second rotor core unit. The first rotor core unit is configured from a first iron core material having a through-hole into which the drive shaft is inserted, and a plurality of first permanent magnets, and includes a first reference surface at which the first iron core material is flush with or protruding further than first permanent magnets. The second rotor core unit is configured from a second iron core material having a through-hole into which the drive shaft is inserted, and a plurality of second permanent magnets, and has a second reference surface at which the second iron core material is flush with or protruding further than second permanent magnets, the second rotor core unit being laminated in an axial direction on the first rotor core unit such that the first reference surface and the second reference surface contact each other.
