Patent ID: 7432704

Claim:
An inductor-type resolver comprising: an inductor-type rotor; and a stator; the stator comprising: a stator iron core including a plurality of magnetic pole portions facing the rotor, wherein the plurality of magnetic pole portions include a first and a second group; a first signal detecting winding including a winding conductor on one or more of the magnetic pole portions belonging to the first group, the first signal detecting winding detecting a first signal; a second signal detecting winding including a winding conductor on one or more of the magnetic pole portions belonging to the second group, the second signal detecting winding detecting a second signal having a phase different from a phase of the first signal; an exciting winding including winding conductors on one or more of the magnetic pole portions, the exciting winding generating a magnetic flux passing through the first and second signal detecting windings through the rotor; and a correction winding including a winding conductor on one or more of the magnetic pole portions other than the one or more of the magnetic pole portions belonging to the exciting winding or the first and second groups, the correction winding being configured to reduce a residual voltage appearing in a one of an output of the first signal detecting winding and the second signal detecting winding.
