Patent ID: 8860271

Claim:
A rotating electric machine comprising: a stator; and a rotor, wherein the rotor includes an iron core including a cylindrical connection portion that surrounds a rotation shaft and a plurality of magnetic pole portions that are disposed radially outside the connection portion, the number of the magnetic pole portions corresponding to the number of poles, the connection portion and the magnetic pole portions being integrated with each other, and permanent magnets disposed between the magnetic pole portions, wherein the magnetic pole portions include body portions respectively provided between adjacent permanent magnets and flange portions that cover at least parts of radially outer surfaces of the permanent magnets while allowing at least parts of the radially outer surfaces to be exposed, wherein each of the permanent magnets includes a tapered portion in at least a part thereof, the tapered portion having a length in a direction perpendicular to the radial direction that decreases radially inward, wherein a maximum value of a length of the permanent magnet in the direction perpendicular to the radial direction is greater than a maximum value of a length of the body portion of the magnetic pole portion in the direction perpendicular to the radial direction, wherein magnet spaces are formed in the iron core at positions between magnetic pole portions and radially outside the connection portion, the magnet spaces extending through the iron core in an axial direction, and wherein the permanent magnets are disposed in the magnet spaces in such a way that radially inner surfaces of the permanent magnets are in close contact with the connection portion and predetermined gaps are formed between the flange portions and radially outer surfaces of the permanent magnets such that the radially outer surfaces do not contact the magnetic pole portions that define the magnet spaces.
