In this paper we present a quick 3D model using reluctance network (RN) of a superconducting inductor dedicated to a synchronous machine. This inductor is made with two kinds of superconducting materials, which are: two coils of NbTi coaxial are fed by a currents in opposed sides and four superconducting rectangular pieces (YBCO) placed between coils for modulation of the magnetic field generated by NbTi coils. For the test, this inductor is fed by 260 A, and is cooled to 4.2 K. The results obtained by 3D RN are compared with FEM and an experimental prototype.
