ROTATING ELECTRIC MACHINE ROTOR, ROTATING ELECTRIC MACHINE, AND POWER GENERATION SYSTEM

PROBLEM TO BE SOLVED: To provide a rotating electric machine rotor used for high-speed rotation capable of obtaining stable torque transmission between a shaft and a permanent magnet by reducing stress working on each member during high-speed rotation. SOLUTION: This rotating electric machine comprises the rotor which includes a rotatably supported shaft 1, a plurality of permanents 2 disposed on outer peripheries of the shaft 1, a permanent magnet retaining member 3 disposed on outer peripheries of the permanent magnets 2 and retaining the permanent magnets 2, at least one permanent magnet retaining part 5 disposed between the retaining member 3 and the permanent magnet 2, and a stator which is disposed on the outer peripheral side of the rotor through a gap and arranged with a winding.
