Abstract
A motor includes a rotor and stator. The stator includes a stator iron core having a substantially annular yoke, and a plurality of teeth extending from the yoke toward the rotor. Each tooth includes an extending portion with a winding wire wound in a concentrated manner to form a coil, and flange portions extending circumferentially from a tip end portion of the extending portion. The plurality of teeth include adjacent first second teeth with coils having identical phases, and adjacent third and fourth teeth with coils having different phases. A first magnetic resistance circumferentially from a tip end portion of the first flange portion to a center of the extending portion of the first tooth is higher than a second magnetic resistance circumferentially from a tip end portion of the second flange portion to a center of the extending portion of the third tooth.
