Filed: 2007-01-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electric rotating machine which attains high performance by improving the roundness of a stator core fitted in and supported by a case, and also to provide a method for manufacturing its stator.  <P>SOLUTION: An arbor 25 moves in the axial direction to move each divided piece 26a of a collet 26 outward in the radial direction. This causes each divided piece 26a to press the inner circumferential surface of the stator core of the stator 10A from the inner diameter side, thereby holding the stator 10A on the same axis as the collet 26. Thereafter, shaping rollers 29 are moved down to press the circumferential surface of the stator core. In that state, the collet 26 is rotated to rotate the stator 10A. This causes the internal circumferential surface of the stator core to be compressed and plastically deformed after the collet 26 and the circumferential surface of the stator core is compressed and plastically deformed by the shaping rollers 29, thereby coaxially correcting the inner circumferential surface and the circumferential surface of the stator core with high roundness.  <P>COPYRIGHT: (C)2008,JPO&INPIT
