Abstract: Provided is a method of manufacturing a resolver having a stator mounted around a rotator and configured to detect a rotational angle of a motor, the method including: forming the stator to have a core with protrusions disposed at a predetermined interval along a rotational direction of the rotator; winding a signal source coil around the protrusions of the core to generate an alternate current (AC) magnetic field when an input voltage signal is applied thereto; and winding a plurality of output signal coils alternately along the rotational direction of the rotator around the protrusions of the core, along the rotational direction of the rotator, to generate induced voltage signals of different phases in response to the AC magnetic field generated by the signal source coil and the rotation of the rotator.
