Abstract: The permanent magnet type reluctance electric motor includes a stator including a stator iron core and having armature coils placed inside slots, and a rotor provided with a plurality of magnetic barriers formed by cavities and placed on an inner side of the stator such that sections where a magnetic flux can easily pass (d-axis) and sections where a magnetic flux cannot easily pass (q-axis) are alternately formed, and made of a rotor iron core having permanent magnets in cavities. The rotor satisfies a relationship of PL/2&pgr;RWqave≧130, where Wqave [m] indicates an average thickness of the rotor iron core on an outer side in a radial direction of the rotor with respect to cavities arranged in a q-axis direction, L [m]; a width in a circumferential direction of the cavities, P; the number of poles and R [m]; the radius of the rotor.

Abstract: Permanent magnets are arranged to be supported by the provision of permanent magnet position-locating projections (12) in permanent magnet embedding holes (5). By optimizing the shape of thin-wall regions (18) and (19) within rotor core (4), leakage of flux generated from the permanent magnets is reduced and the strength of the thin-wall regions where stress is concentrated is ensured.
