PURPOSE: To decrease process manhours and to improve the accuracy at a low cost in a rotary-transformer type resolver by forming a rotor winding of a signal generating part and a detecting winding of a rotary transformer part of a continued conductor pattern on the same sheet coil. ;CONSTITUTION: A fixed-side sheet coil 2 is fixed to the gap surface of a fixed- side core 1 by bonding and the like. A primary winding 21 of a rotary transformer part and a detecting winding 22 of a signal generating part are formed by print winding and bonded to the upper and rear surfaces of an insulated substrate 23. A secondary winding 41 in a rotating-side sheet coil 4 is wound in the spiral shape so as to correspond to the winding 21 of the coil 2. One end part of the respective secondary winding patterns is connected by way of a through hole. An exciting winding 42 is connected by way of the through hole of the concentrated winding conductors of the upper and rear surfaces. When an AC voltage is applied on the winding 21 of the coil 2, the AC voltage is induced in the winding 41 of the coil 4. The induced voltage is generated in the winding 22. The inducted voltage is detected, and the rotating angle of the rotor is detected.;COPYRIGHT: (C)1996,JPO
