Patent ID: 7525231

Claim:
A stator for an electric motor, comprising: a core including a plurality of teeth extending radially and spaced from each other about a center axis with tips of the teeth being oriented toward said center axis, said teeth including a first tooth and a second tooth; and wire wound a number of times around each of said teeth of said core so as to form coils around the teeth, respectively, wherein: the diameter of said wire is substantially the same along the length of said wire; the respective distances between said center axis and each of the tips of said teeth are substantially the same; a wire winding height of the wire around said first tooth is less than a wire winding height of the wire around said second tooth, the wire winding heights corresponding to the overall thicknesses of the coils, respectively, in the direction of the center axis, and the number of windings of the coil disposed around said first tooth is substantially the same as the number of windings of the coil disposed around said second tooth.
