A rotor for a rotary electric machine includes a rotor core which is formed by crimping laminated steel plates so as to be opposed to a stator, and has pairs of magnet housing holes disposed in a V shape, and pairs of magnets housed in the magnet housing holes. The rotor core has a crimped portion formed in a q axis core portion positioned between the two magnet poles, which are adjacent to each other in a circumferential direction, a first flux barrier formed between the q axis core portion and the magnet, and a pair of second flux barriers which enlarges from an end positioned at a center side of the magnet pole of the magnet housing holes toward a central axis of the rotor core. The crimped portion is formed so that distances between the crimped portion and both the first and second flux barriers are equal. |

1. A rotor for a rotary electric machine, comprising:
a rotor core which is formed by crimping a plurality of steel plates laminated in an axial direction so as to be opposed to a stator in a radial direction, and has a plurality of pairs of magnet housing holes, each of the pairs being disposed in a V shape so that a distance between the magnet housing holes increases toward the stator; and a plurality of pairs of magnets each of which is housed in the pair of the magnet housing holes to form a magnet pole, wherein the rotor core has a crimped portion which is formed in a q axis core portion positioned between two of the magnet poles, which are adjacent to each other in a circumferential direction and have different polarities, a first flux barrier formed between the q axis core portion and the magnet, and a pair of second flux barriers which enlarges from an end positioned at a center side of the magnet pole of the respective magnet housing holes, which are a pair, toward a central axis of the rotor core, and the crimped portion is formed so that a distance between the crimped portion and the first flux barrier is equal to a distance between the crimped portion and the second flux barrier. |
