Abstract
A motor stator in one implementation includes a plurality of teeth disposed in a radial form centered about a predetermined center axis, insulators covering the plurality of teeth, and a plurality of coils provided on each of said plurality of teeth by winding conductors onto the insulators through to multiple layers. At one axial end of the plurality of areas where the insulators cover each of the plurality of teeth, the radius of curvature of the conductor windings on the ending side is larger than the radius of curvature on the starting side. The insulators in a motor stator in another implementation are provided with a first partition and a second partition that, relative to the axial center of the plurality of teeth, respectively cover one side and the other side each tooth.
