We present a new kind of superconducting inductor for the synchronous machine. This inductor is composed of a two superconducting coils having the same axis and fed by a currents with the same direction. A superconducting bulk is used in order to achieve a variation of the flux density in the air-gap. Due to the superconducting coil the value of the magnetic field in the airgap could be upper than 4T. With the proposed superconducting inductor, we obtain a two-poles electrical machine with an important specific torque and specific power. Therefore these kind of superconducting motor could be sized for aircraft application.
