<P>PROBLEM TO BE SOLVED: To provide a stator of a rotary electric machine capable of preventing the generation of buckling in a split core by compression stress in a circumferential direction acting on the split core, and a manufacturing method of the same. <P>SOLUTION: A stator 20 includes: a stator core 30 formed by annularly assembling a plurality of split cores 32 split in the circumferential direction; an outer cylinder 37 fittingly fixed to an outer periphery of the stator core 30 by shrinkage fitting; and a stator winding 40 wound around the stator core 30. On both sides in the axial direction of the stator core 30, binding members 61 and 62 held by the outer cylinder 37 for regulating deformation of the split core 32 in the axial direction are disposed. The binding members 61 and 62 are fittingly fixed to the outer cylinder 37 together with the split cores 32 when the outer cylinder 37 is fittingly fixed to the annularly assembled split cores 32 by shrinkage fitting. <P>COPYRIGHT: (C)2012,JPO&INPIT |
