<p>PROBLEM TO BE SOLVED: To provide a rotor of a dynamo-electric machine which facilitates recycling of metal rare earth, without using adhesive for fixing a permanent magnet, and to provide a manufacturing method therefor.SOLUTION: A rotor 200 of a dynamo-electric machine has a cylindrical rotor core 205, and a plurality of permanent magnets 215 disposed in the magnet insertion holes 210 of the rotor core. The rotor core is constituted of a first rotor core 206 formed by laminating magnetic steel sheets having the magnet insertion holes, and a second rotor core 207 having a magnetic steel sheet on which protrusions 208 are disposed at positions corresponding to the magnet insertion holes. The second rotor core is disposed at the axial end of the rotor core so as to be adjacent to the first rotor core, and the permanent magnets are fixed by the protrusions of the second rotor core in an axial direction.</p> |
