    摘要： An object of the present invention is to provide an internal permanent magnet type rotating electrical machine capable of maintaining compactness and high output and reducing vibration and noise caused by electromagnetic force. The rotating electrical machine of the present invention has an annular stator and a rotor that is arranged inside the stator with an air gap interposed between the stator and the rotor. The stator has a stator iron core provided with a plurality of slots at circumferential intervals and a coil received in each of the slots. The rotor has a rotor iron core, a plurality of permanent magnets embedded in a plurality of magnetic pole forming positions that are set along an outer circumference of the rotor iron core, an iron core section that faces the air gap and is magnetized by the permanent magnets to form a magnetic pole on an air gap fronting face at each of the magnetic pole forming positions, and an axially extending recess formed at a circumferentially central part of the air gap fronting face of each of the iron core sections.

    摘要： For an electrical reluctance rotary machine, a stator has a winding as an armature, and a rotor has permanent magnet implanting slots provided in a rotor core at lateral sides magnetic poles configured to produce reluctance torque along directions of magnetic flux passing through the magnetic poles to produce reluctance torque, and permanent magnets inserted in the permanent magnet implanting slots so as to cancel magnetic flux of the armature intersecting that magnetic flux, to control a magnetic field leaking at ends of the magnetic poles, having circumferential magnetic concavo-convex. The electrical reluctance rotary machine is configured to meet a relationship, such that 1.6 ≤ P × W pm R ≤ 1.9 where Wpm [mm] is a width of permanent magnet, R [mm] is an outer-diametrical radius of the rotor, and P is the number of poles.
