PROBLEM TO BE SOLVED: To provide a permanent magnet embedded rotor for a rotary electric machine capable of improving a performance of the rotary electric machine.SOLUTION: A rotor core 2 is formed with: a d-axis core part 2D which is positioned radially outsides relatively to a permanent magnet 10; q-axis core parts 2Q that are arranged side by side in a circumferential direction relatively to the d-axis core part 2D; continuous slits 31 and 32 which extend towards an opposite side of the permanent magnet 10 in the circumferential direction continuously to flux barriers 21 and 22 and have widths W31 and W32 in a radial direction being narrower than the flux barriers 21 and 22; independent slits 41 and 42 which extend in the circumferential direction at positions separated radially to the outside relatively to the continuous slits 31 and 32 and oppose the continuous slits 31 and 32 in the radial direction; and a plurality of bridges 51 and 52 which are arranged side by side radially inside and outside of the independent slits 41 and 42 between the continuous slits 31 and 32 and an outer edge 2E of the rotor core 2, couple and support the d-axis core part 2D and the q-axis core parts 2Q.SELECTED DRAWING: Figure 2 |
