Abstract:
A rotary electric-machine rotor includes: a rotor core made of magnetic material, the rotor core having magnet holes; magnets disposed in the magnet holes; resin portions disposed in at least part of gaps between the magnet holes and the magnets, the resin portions extending in the axial direction; and end plates disposed adjacent to end surfaces in an axial direction of the rotor core. The end plates are members made of magnetic material. The end plates cover end surfaces of the magnets in the axial direction and end surfaces of the resin portions in the axial direction, and each of the end plates having at least one holes disposed in a position that faces at least one part of the end surfaces of the magnets.
