<P>PROBLEM TO BE SOLVED: To provide a stator for a rotary electric machine that has divided cores constructed so as to reduce the number of fastening bolts without causing loosening of the bolts and allow radial access for annular arrangement. <P>SOLUTION: Both circumferential side surface 24c, 24f of a fixed portion 24b of a divided core 24 have a first groove 24d and a second groove 24e, semicircular and extending axially, formed in two respective radial positions. The first grooves 24d of circumferentially adjacent divided cores 24 abut each other to form a first circular and axially extending hole 24g, and the second grooves 24e of circumferentially adjacent divided cores 24 abut each other to form a second circular and axially extending hole 24h. First bolts 26A and second bolts 26B are circumferentially alternately passed through the first holes 24g and the second holes 24h, and the bolts 26A, 26B fasten the fixed portions 24b to a base 25. <P>COPYRIGHT: (C)2012,JPO&INPIT |
