Abstract
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.
