PROBLEM TO BE SOLVED: To increase a magnetic flux amount without decreasing a q-axis inductance in a stator side area of a pair of magnets disposed in a V-shape in a rotor core.SOLUTION: A rotor 10 comprises: a rotor core 11 including a plurality of pairs of magnet housing holes 12 which are in pairs and which are arranged in a V-shape so that a countervailing distance therebetween becomes larger toward the side of a stator 30; and a plurality of pairs of magnet 13 which are accommodated in the magnet housing holes 12 arranged in the V-shape and each of which forms one magnetic pole. The rotor core 11 includes a first flux barrier 16 protruding into the stator 30 side at a magnetic pole central side end part on a stator side wall surface 12a of a pair of the magnet housing hole 12 arranged in the V-shape. A protrusion height H of the first flux barrier 16 is set in the range satisfying the relational expression: 0.12*R≤H≤0.29*R, when an intersection point between a magnet pole center line C1 and an inner peripheral surface of the stator 30 is defined as P1, and the shortest distance from the intersection point P1 to the stator side wall surface 12a is defined as R. |
