摘要： A rotor includes a rotor core that is made of electromagnetic steel sheets rotating around a central axis and laminated in an axial direction, and that has multiple flux barriers penetrating the electromagnetic steel sheets along the axial direction. At least some of the multiple flux barriers are provided with a first penetrating portion and a second penetrating portion arranged in the radial direction, the first penetrating portion housing a magnet and the second penetrating portion housing a conductive non-magnetic conductor.
