PROBLEM TO BE SOLVED: To provide a rotor of rotary electric machine capable of reducing torque ripples.SOLUTION: A rotor 30A includes: a rotor core 31 which has plural magnet storage holes 32 arranged in a circumferential direction; plural permanent magnets 33 forming plural magnetic poles, which are stored in the magnet storage holes 32 in which the polarity changes alternately in a circumferential direction. The rotor core 31 has a q shaft core part 34 which is positioned between two magnetic poles neighboring each other in a circumferential direction each having a different polarity. In the q shaft core part 34, the center P2 of width in a circumferential direction at the outer periphery side is displaced in a reverse rotation direction of the rotor with respect to the center P1 of the width in the inner circumferential direction.SELECTED DRAWING: Figure 2 |
