摘要

PPROBLEM TO BE SOLVED: To provide a laminate core for rotors, a rotor core, a rotor for permanent-magnet synchronous rotating electrical machines equipped therewith, and a permanent-magnet synchronous rotating electrical machine, and a vehicle, an elevator, and a finishing machine, using the rotating electrical machine, wherein required laminate core materials are reduced without influence on the magnetic characteristics of a motor. PSOLUTION: The laminate core 1 for rotors includes: arc-shaped unit cores 2 for forming a rotor core, having a permanent magnet mounting portion 3a for placing a permanent magnet; and multiple swaging portions 7 formed in the unit cores 2 so that the following is implemented: when a predetermined number of annular core plates formed by arranging multiple unit cores 2 so that they annularly adjoin to one another and are coupled together are laminated in the vertical direction, the annular core plates are coupled together by swaging. The swaging portions 7 of the unit cores 2 are provided opposite to the permanent magnet mounting portions 3a so that the swaging portions are undulately arranged in areas where the magnetic flux path of the rotor is not influenced.
