For the 1 pole, the 2 pieces of same-polarity permanent magnets (12) are embedded into the V-character pattern. The configuration of each embedded permanent magnet (12) is designed as follows: From the thickness of the permanent-magnet edge portion on the inner-diameter side of the rotor iron-core (9), which becomes the center of the V-character pattern, the thickness of the permanent magnet (12) gradually increases toward the outer-diameter side of the rotor iron-core (9), which become the right and left edge portions of the V-character pattern.
