Abstract
An axial-air-gap rotating electric machine with a stator bobbin is provided. The bobbin renders the respective turn counts of windings in the machine the same and minimizes the lengths of connecting wires between continuous windings regardless of the continuous turn count, the direction in which each winding is wound, and whether the number of stages is odd or even. The bobbin, which has a tubular shape that substantially matches the exterior shape of a core, is provided with flanges that extend outwards from near the respective openings in the bobbin. One of the flanges has two first notches, and the other flange has a second notch. The axial positions of the starting and finishing ends of coils on adjacent stator cores are the same, and the flanges containing the notches through which the ends of the coils are run are on the same side with respect to the openings.
