摘要： PROBLEM TO BE SOLVED: To reduce a torque ripple, an oscillation and a noise by effectively obtaining an effect similar to a skew effect.
SOLUTION: The rotor of a reluctance type rotating electric machine includes a rotor core obtained by laminating many annular silicon steel sheets and divided into four blocks 3, 4, 4 and 3. The block 3 is formed by displacing a magnetic uneven part by a predetermined angle in an opposite direction to a rotating direction X with a centerline passing a key engaged with the keyway of a rotary shaft as a reference, and the block 4 is formed by displacing a magnetic uneven part by a predetermined angle in the rotating direction X with the centerline as a reference. Thus, for example, the locus of the centerline Lc passing a center of the magnetic recesses of the blocks 4, 4, and the locus of the centerline Lb passing a center of magnetic recesses of the blocks 3, 3, are not disposed on one straight line to become a zigzag state, and the effect similar to the skew effect can be obtained.
