<P>PROBLEM TO BE SOLVED: To provide a stator having a structure capable of improve accuracy of a tip location in a lead side of a segment coil inserted into a slot of a stator core without sacrificing a stator space factor, a manufacturing method of the stator, and a manufacturing apparatus for the stator. <P>SOLUTION: A stator 10 comprises: a segment Sg which is formed by applying bending work to a flat angle conductor D; and a stator core 20 which includes a slot 12. At a lead portion Sga of the segment Sg, which protrudes from an end surface of the stator core 20, a shift portion Sf is decentered from a root-side flexion point P5 to a radial direction of the stator core 20 when viewed from an in-slot conductor portion Sgb fitted into the slot 12. In the lead portion Sga, a third lead portion Sga3 includes a first tip-side flexion point P1, and a fifth lead portion Sga5 inserted into the same slot 12 as the third lead portion Sga3 includes a second tip-side flexion point P2. A height from the end surface 20a of the stator core 20 to the first tip-side flexion point P1 is different from a height to the second tip-side flexion point P2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
