Claim 0:
1. A rotor comprising:
a rotor core; and
a plurality of first magnets and second magnets disposed along an outer circumferential surface of the rotor core,
wherein the second magnets are disposed between the first magnets, and
a curvature of an outer circumferential surface of the first magnet is greater than a curvature of an outer circumferential surface of the second magnet, wherein:
with respect to a thickness which is a distance from an inner circumferential surface of the first magnet to the outer circumferential surface of the first magnet, a thickness of a central portion of the first magnet and a thickness of an end portion of the first magnet are different;
with respect to a thickness which is a distance from an inner circumferential surface of the second magnet to the outer circumferential surface of the second magnet, a thickness of a central portion of the second magnet and a thickness of an end portion of the second magnet are different;
the thickness of both end portions of the first magnet are the same; and
the thickness of the end portion of the first magnet is less than the thickness of the end portion of the second magnet disposed to face to the end portion of the first magnet.
