    Abstract: A rotor includes a plurality of magnets, and an annular rotor core having a plurality of magnet insertion holes formed in a circumferential direction, into which the magnets are respectively inserted, in which each of the magnet insertion holes is formed with a protruding portion A on an inner wall surface on an inner diameter side in a radial direction of the rotor, and each of the magnets is formed with a recessed portion that is fitted to the protruding portion A when the magnet is inserted into the magnet insertion holes. With this configuration, fixation of the magnets is facilitated, and generation of chipping and vibration noise due to a movement of the magnets at the time of activation or rotation can be suppressed, thereby enabling to provide the rotor having high quality and high reliability.

    Abstract: In a permanent-magnet-embedded electric motor, at the distal ends of base sections of teeth sections of a stator core, increased magnetic-resistance sections, which have magnetic resistance larger than magnetic resistance of the base sections, are provided. Given that a minimum interval in the circumferential direction between the base sections adjacent to each other is represented as La, an interval of a minimum gap between the teeth sections adjacent to each other is represented as Lb, and an interval of a gap between a rotor and a stator is represented as Lg, a relation of La>2Lg>Lb holds. Due to such a configuration, it is possible to provide the electric motor that does not spoil a magnetic characteristic of the rotor and that is excellent in a demagnetization characteristic.
