Abstract:
A rotary electric machine includes a stator in which a plurality of armatures each have a coil formed by a winding wire wound in plural layers around bobbins mounted to a magnetic pole tooth, which are disposed annularly on an inner circumference of a cylindrical frame. The coil is formed by the winding wire being wound with a constant feed pitch in parallel with slots of the bobbins in plural layers. The winding wire forming a first layer of the coil is shifted by half the feed pitch between a left side and a right side of a center axis of the coil as viewed from a plane perpendicular to a stacking direction of a stacked iron core.
