The aim of this paper is to present a new concept of superconducting inductor for a synchronous machine. This inductor consists of two superconducting coils. These coils have the same axis and are fed by the same current. A superconducting bulk is placed between the two coils in order to obtain a variation of the flux density in the air-gap. This bulk is surrounded by a ferromagnetic material to improve the distribution of the air-gap magnetic field. With the proposed superconducting inductor,
