Abstract
The present invention relates to a resolver having a stator for detecting the rotational position of a rotor rotating at the inner center thereof. The stator includes: a stator core having a cylindrical shape; a plurality of excitation windings attached to the inner surface of the stator core at a predetermined distance in the circumferential direction, each of the plurality of excitation windings being tightly wound; a plurality of sine output windings stacked and attached to the patterns of the excitation windings in the circumferential direction, each of the plurality of sine output windings being loosely wound; and a plurality of cosine output windings stacked and attached to the patterns of the excitation windings in the circumferential direction, 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 winding distribution.
