摘要： A resolver can make accurate angle detection in an entire detection range. The resolver includes a resolver stator having an excitation winding of one phase adapted to be excited by a power supply and a first and a second output winding of two phases for outputting a change in the density of magnetic flux as a voltage, a resolver rotor arranged at a central portion of the resolver stator so as to cooperate with the resolver stator for changing a gap permeance between the resolver rotor and the resolver stator in accordance with the rotation of the resolver rotor, and a detection error correction part that corrects an angle detection error of the resolver by using the value of a Lissajous radius of a circular Lissajous waveform obtained from the amplitudes of an output signal Scos from the first output winding and an output signal Ssin from the second output winding.
