ABSTRACT:
In a stator for an automotive alternator, the inner circumferential surfaces of the bridge portions are placed in contact with the end surfaces of the stator core without any gaps so that the spatial ratio occupied by the clusters of stator windings belonging to the bridge portions in the coil ends of the stator coil is at high density. The method of manufacture comprises a step of manufacturing a parallelepiped laminated body having a plurality of slots by laminating a plurality of comb-shaped strips each having a band portion and a plurality of teeth, a step of inserting into the slots from the side of the openings of the slots a stator coil comprising bridge portions and axially parallel portions having current generating portions, a step of extending the ends of the teeth of the laminated body in the longitudinal direction of the laminated body, and a step of bending the laminated body to form a cylindrical shape.
