ROTOR STRUCTURE OF ROTARY ELECTRIC MACHINE

A rotor structure including a rotor, a stator, and magnetic pole parts is provided. Each magnetic pole part includes a radially-magnetized fixed magnetic-force magnet, first variable magnetic-force magnets which are disposed radially outward of, and at both circumferential end sides of, the fixed magnetic-force magnet, respectively, and have a magnetization state that is changeable in the circumferential direction by a magnetic flux, and a high magnetic-reluctance part formed between the fixed magnetic-force magnet and the first variable magnetic-force magnet in the circumferential direction and having a magnetic reluctance higher than the rotor core. The high magnetic-reluctance part includes a first vertically extending part radially extending at a position near the fixed magnetic-force magnet, a second vertically extending part radially extending at a position near one first variable magnetic-force magnet in the circumferential direction, and a laterally extending part connecting the first and second vertically extending parts in the circumferential direction.
