摘要： A rotor includes first and second permanent magnets provided in each magnetic pole inside a rotor core. The rotor is configured such that when a first end of the first permanent magnet located on the outer circumferential side of the rotor core and the second permanent magnet side is located at a position that faces a first end in the circumferential direction of one of teeth of a stator, a second end of the first permanent magnet located on the axis of rotation side of the rotor core and the second permanent magnet side is located at a position that faces a second end in the circumferential direction of the tooth that faces the first end of the first permanent magnet.

摘要： A rotor includes a rotor core; and first permanent magnets and second permanent magnets arranged in the rotor core so that, on a cross-sectional plane of the rotor core perpendicular to the rotation axis thereof, the first and second magnets corresponding to each other define the letter V having an apex pointing toward the rotation axis. The first and second magnets corresponding to each other are arranged so that a straight line interconnecting the rotation axis and the apex of the letter V is interposed therebetween, an angle of the first magnet relative to the straight line being smaller than that of the second magnet relative to the straight line, a width of the first magnet in the direction parallel to the first side of the letter V being smaller than that of the second magnet in the direction parallel to the second side of the letter V.

摘要： A permanent magnet synchronous rotating electric machine includes a rotor and a stator. The rotor includes a first hole, a second hole, a first magnet, and a second magnet. The second hole is provided on an opposite side with respect to a center line extending along a radial direction of the rotor. The first magnet is provided in the first hole and extends along a first longitudinal axis inclined at a first acute angle with respect to the center line. The second magnet is provided in the second hole and extends along a second longitudinal axis inclined at a second acute angle with respect to the center line. The second acute angle is smaller than the first acute angle.
