Claim:
1. A resolver comprising a stator for detecting a rotational location of a rotor that rotates in an inner center, wherein the stator comprises: a stator core having a cylindrical shape; an excitation winding pattern, a sine output winding pattern, and a cosine output winding pattern which are stacked to each other; wherein the excitation winding pattern is defined by a plurality of excitation windings attached to an inner surface of the stator core at a specific interval in a circumferential direction, and each of the plurality of excitation windings forms a concentration winding; wherein the sine output winding pattern is defined by a plurality of sine output windings provided in the circumferential direction in such a way as to be stacked, and each of the plurality of sine output windings forms a distribution winding; and wherein the cosine output winding pattern is defined by a plurality of cosine output windings provided in the circumferential direction in such a way as to be stacked, the sine output windings and the cosine output windings being alternately attached such that the sine output windings and the cosine output windings have the same distribution winding.
