Rotor and rotary electric machine

A rotor, comprising:

• a rotor shaft extending in the axial direction of a rotation center axis;
• a plurality of permanent magnets extending in the axial direction and arranged symmetrically with respect to an M-axis that extends perpendicularly from the rotation center axis when viewed in a cross-section perpendicular to the rotation center axis;
• and
• a rotor core mounted radially outside the rotor shaft, the rotor core having the electromagnetic steel plates stacked such that the M axes overlap when viewed in the axial direction, wherein magnetic poles are arranged evenly in the circumferential direction, each magnetic pole including a flux-barrier band that is formed substantially convexly toward the rotation center axis and connects one side of an outer peripheral surface with other side of the outer peripheral surface, the flux barrier band having regions accommodating the permanent magnets, non-magnetic regions, and bridges, the rotor core comprising the non-magnetic regions connecting the outer peripheral surface and the permanent magnets, wherein
• the magnetic poles include outer core sections positioned outside in the radial direction of the flux-barrier band and an inner core section positioned inside in the radial direction of the flux-barrier band,
• when a boundary point farther from the M-axis is defined as a boundary point P11, a boundary point closer to the M-axis is defined as a boundary point P21 among the boundary points between the outer edge forming the outer peripheral surface of the outer core section and the outer edge facing the non-magnetic region, and a boundary point closer to the boundary point P11 is defined as a boundary point P12, and a boundary point closer to the boundary point P21 is defined as a boundary point P22 among the boundary points between the outer edge forming the outer peripheral surface of the inner core section and the outer edge facing the non-magnetic region, and
• when a circumferential angle formed by a line connecting boundary point P11 to the rotation center axis and the M-axis is defined as circumferential angle Θd1, a circumferential angle formed by a line connecting boundary point P12 to the rotation center axis and the M-axis is defined as circumferential angle Θq1, a circumferential angle formed by a line connecting boundary point P21 to the rotation center axis and the M-axis is defined as circumferential angle Θd2, and a circumferential angle formed by a line connecting boundary point P22 to the rotation center axis and the M-axis is defined as circumferential angle Θq2,
• circumferential angle Θq1 is larger than circumferential angle Θq2 in a case that circumferential angle Θd1 is larger than circumferential angle Θd2, and
• an adjacent magnetic pole has a shape that is inverted with respect to the M-axis of the specified magnetic pole when viewed from a specified magnetic pole.
