<p>PROBLEM TO BE SOLVED: To provide a permanent magnet buried type rotary electric machine capable of suppressing torque ripple.SOLUTION: A pair of concave portions 21A and 21B are formed on both sides of a bridge 18 on an outer peripheral surface of a rotor 15. The pair of concave portions 21A and 21B are connected by a convex portion 22 formed so as to cover the bridge 18 and gaps 19A and 19B on the radial direction outside of the rotor 15. In the radial direction of the rotor 15, a shortest distance H1 from deepest portions 23D and 24D of the concave portions 21A and 21B up to permanent magnet storage parts 16A and 16B is set shorter than a shortest distance H2 from the convex portion 22 up to the gaps 19A and 19B. Consequently, magnetic resistance in the vicinity of the pair of concave portions 21A and 21B can be efficiently enhanced.</p> |
