| description | The present invention provides a magnet-embedded rotor for a rotating electrical machine wherein scattering of the magnet can be prevented at low cost by filling an adhesive for holding a permanent magnet so as to be inclined along the axial direction of a rotor core so that the adhesive secures the magnet and prevents scattering of the magnet on the side with a larger amount of adhesive. In the magnet-embedded rotor for a rotating electrical machine according to the present invention, a magnet is accommodated in a magnet housing hole which passes axially through the rotor core held by a shaft, and the adhesive is filled and cured in a gap between the permanent magnet in the magnet housing hole and the rotor core to secure the permanent magnet to the rotor core. A first end plate is held by the shaft in contact with one axial end of the rotor core to close an opening at one axial end of the magnet housing hole. The gap between the permanent magnet in the magnet housing hole and the rotor core is formed gradually broadening from one axial end toward the other axial end in the magnet housing hole so that the amount of the adhesive filled in the gap gradually increases from the one axial end toward the other axial end in the magnet housing hole. |
