<P>PROBLEM TO BE SOLVED: To join split cores together tightly without using welding or the like. <P>SOLUTION: A rotary electric machine includes: a stator core that has first teeth cores to fourth teeth cores each including a plurality of laminated T-shaped magnetic pole pieces each having a tenon and a dovetail groove formed at an end of a yoke; and a rotor that is provided on an inner side of the stator core. The third teeth cores are identical in shape size to the second teeth cores, and the fourth teeth cores are identical in shape size to the first teeth cores. The first teeth cores and the second teeth cores are alternately arranged in a circular pattern by engaging the respective tenons with the respective dovetail grooves, and the third teeth cores and the fourth teeth cores are also alternately arranged in a circular pattern by engaging the respective tenons with the respective dovetail grooves. The tenons of the first teeth cores are smaller in width at the base than the tenons of the second teeth cores, and the dovetail grooves of the first teeth cores are larger in width at the base than the dovetail grooves of the second teeth cores. <P>COPYRIGHT: (C)2012,JPO&INPIT |
