    摘要: An interior permanent magnet motor includes a rotor and a stator. The rotor includes a rotor core. The rotor core is formed by laminating steel plates each including pairs of magnet insertion holes and pairs of cutouts. Each pair of magnet insertion holes includes two magnet insertion holes that are arranged in a V-shape, the wide end of which is relatively closer to the outer edge with a support portion located in between. Each pair of cutouts is formed at q-axis ends of the corresponding magnet insertion holes, and includes two cutouts connected to the outer edge of the rotor core. In a state where the permanent magnets are inserted in the magnet insertion holes, a gap is formed at a d-axis end of each magnet insertion hole.

    摘要: A press-forming device includes a punch and a die, as a mold to be measured, and a strain measurement means arranged within the mold and measuring a strain amount generated by press-forming. The strain measurement means is positioned at the press-direction side relative to a radius end of a die shoulder on the material flow-out side when the mold is positioned at a lower dead point of press-forming. The strain measurement means is preferably positioned within a region defined by a surface which is away from the center of curvature of a curved surface of the mold by the distance ten times R, where R is a curvature radius of the curved surface.

    摘要: A galvannealed steel sheet includes: a steel sheet; a galvannealed layer which is formed on at least one surface of the steel sheet and includes Al, Fe, and the balance composed of Zn and inevitable impurities; and a composite oxide layer of Mn, Zn, and P which is formed on the surface of the galvannealed layer, includes Mn, P, and Zn, and has the P/Mn ratio of equal to or higher than 0.3 and equal to or lower than 50. The galvannealed layer includes a flat portion having an area ratio of equal to or higher than 10% and equal to or lower than 70% and a rough portion which is at a position closer to the steel sheet than the flat portion at the interface of the galvannealed layer and the composite oxide layer 5. The composite oxide layer of Mn, Zn, and P contains an amorphous compound.
