In a permanent magnet motor, a side portion of a flange portion provided on each of a plurality of teeth faces a side portion of a flange portion provided on a tooth that projects and is adjacent in a circumferential direction of a stator iron core. When the height of a side portion of a flange in a radial direction of the stator iron core is denoted by h and the length of a magnetic air gap is denoted by g, a relationship of 1 ≤ h/g ≤ 2 is satisfied. In addition, when the distance between the surfaces of adjacent flanges facing each other in a circumferential direction is denoted by a, a relationship of a/g ≥ 0.2 is satisfied. |
