Patent ID: 7827672

Claim:
A method of manufacture for a stator for an automotive alternator comprising: 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 substantially rectangular teeth disposed substantially parallel to each other and extending perpendicularly relative to a longitudinal direction of said band portion, each tooth including an end portion having a slit, which is formed in a radial center of said end portion and is perpendicular to the longitudinal direction of said band portion; inserting into said slots from a side of openings of said slots a stator coil being a cluster of three phases of connected stator windings comprising: axially parallel portions being those portions which are substantially parallel to a central axis of said stator coil having current generating portions being those portions disposed within said slots and generating electric current; and bridge portions being circumferential portions connecting axially parallel portions to each other within each of said three phases of windings; subsequent to the inserting, spreading said end portion of each of said teeth, from a corresponding slit, in a longitudinal direction of said laminated body, thereby newly forming pairs of projection portions from the end portions which are spread apart, the projection portions of each pair extending away from one another in the longitudinal direction of said laminated body; and bending said laminated body to form a cylindrical shape.
