<p><P>PROBLEM TO BE SOLVED: To provide a rotor having a highly reliable structure in which a wedge does not move beyond an allowable movement dimension in an axial direction. <P>SOLUTION: A rotor 2 includes a shaft 21, a rotor field winding 22, a wedge 23, a lock groove 212, a caulking portion 231, first punch locks 213, and second punch locks 232. The caulking portion 231 protrudes from the wedge 23 and is fitted to the lock groove 212. The first punch locks 213 protrude from an edge of a first coil slot 211 adjacent to the lock groove 212 toward the wedge 23 to come into contact with the wedge 23. The second punch locks 232 protrude from the wedge 23 toward the edge of the first coil slot 211 to come into contact with the edge of the first coil slot 211 and the first punch locks 213 so as to sandwich the first punch locks 213 with respect to the caulking portion 231 in an axial direction L. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
