Abstract
A permanent magnet motor is provided in which, in flanges each provided in a plurality of teeth, lateral side portions of the flanges oppose to lateral side portions the flanges being provided in adjacent teeth and protruding in a circumferential direction of a stator core; when a height in the lateral side portion of the flanges in a radial direction of the stator core is defined as 'h,' and the length of a magnetic air gap is defined as 'g,' the relationship “1≤h/g≤2” is held; and also, when a circumferential distance between opposing faces of the flanges being adjacent to each other is defined as “a,” the relationship “a/g≥0.2” is satisfied.
