PROBLEM TO BE SOLVED: To provide a rotor for a rotary electric machine capable of reducing facility cost, material cost or processing cost and obtaining the rotor of satisfactory motor characteristics, the rotary electric machine, and a manufacturing method of a laminate core of the rotor.SOLUTION: A rotor 1 for a rotary electric machine is disposed in which a laminate core 70 comprises an annular composite core 60 in which a plurality of composite cores 50 including a plurality of fan-shaped core pieces 5a and core piece coupling parts 5b which are coupled to form permanent magnet insertion groove parts 5a are disposed in an annular shape while securing a void 50a for inserting a permanent magnet 20 in an axial direction of the rotor 1 between the neighboring composite cores 50. The laminate core 70 is formed by laminating a plurality of annular composite cores 60 in the axial direction of the rotor 1. In the plurality of annular composite cores 60, one composite core 50 forming one of the annular composite cores 60 neighboring in the axial direction of the rotor 1 is laminated over the core pieces 5a of two neighboring composite cores 50 among the composite cores 50 forming the other annular composite core 60. |
