<p>Provided is a rotary electric machine having a stator for which a small feed pitch is maintained for all turns, interference between adjacent magnetic pole teeth is prevented, and an improvement in coil space factor can be achieved. Provided is the rotary electric machine in which a stator (1) is configured by disposing a plurality of armatures (3), in which a coil (10) is formed by winding a plurality of layers of a wire (13) for winding around bobbins (7, 8) fitted to magnetic pole teeth (6), in an annular shape in the inner circumference of a tubular frame (2), wherein the coil (10) is formed by winding in parallel a plurality of layers of a wire for winding inside of slots (7d, 8d) of the bobbins (7, 8) at a uniform feed pitch (P), and the wire for winding that forms the first layer of the coil is offset by only half (P/2) of the feed pitch (P) with respect to the left and the right of the center axis (10c) of the coil when viewed from a plane perpendicular to the layering direction of the layering core (4).</p> |
