PURPOSE:To facilitate the manufacture and assembling of windings a great deal, by forming a pair of stator windings and a rotor winding in a disc to be arranged to face each other so as to enable miniaturization with a drastically reduced axial length of a resolver. CONSTITUTION:When current with I=Im Sinomegat is fed to a first stator winding 17 and current with I=Im Cosomegat to a second stator winding 18, a magnetic flux is generated in a loop-shaped magnetic path piercing the stator windings 17 and 18 and the rotor winding 19 due to a magnetic field to be generated with the pair of stator windings 17 and 18. With such an arrangement, an induced voltage is generated in the rotor winding 19, the phase of the voltage induced in the rotor winding 19 varies with the value of the angle theta of rotary deviation of the rotor winding 19 with the stator windings 17 and 18. Thus, the rotary angle position of the input shaft 10 can be detected by checking the phase of a signal to be outputted from the rotor winding 19.
