Rotor, rotary electric machine and manufacturing method of rotor

A rotor comprising:

• a rotor shaft extending in a direction of a rotation center axis;
• a pair of first magnets extending in the direction of the rotation center axis, arranged symmetrically with respect to a d-axis extending perpendicularly from the rotation center axis, and each having a rectangular cross-sectional shape in a cross-section perpendicular to the rotation center axis;
• a pair of second magnets arranged radially inward of the first magnets and symmetrically with respect to the d-axis, and each having a rectangular cross-sectional shape;
• and
• a rotor core attached to the radially outward of the rotor shaft and having a plurality of magnetic poles, each magnetic pole including a flux barrier band that connects one with other of the outer peripheral surface, the flux barrier band being formed substantially convexly toward the rotation center axis and including a magnet-housing region in which the first magnet and the second magnet are mounted, a non-magnetic region, and a bridge,
• wherein the second magnet has a greater thickness than the first magnet, and the second magnets form greater angle than the first magnets.
