1. A superconducting electric machine comprising:
an inductor comprising superconducting pellets circumferentially distributed around an axis of the electric machine;
an armature comprising coils, each of the coils having a radially inner edge and a radially outer edge, the radially inner edge and the radially outer edge extending along a circumferential direction with respect to the axis;
a flux barrier extending circumferentially with respect to the axis, the flux barrier extending between the superconducting pellets and the armature such as to at least partially cover at least one among the radially outer edge and the radially inner edge of all or part of the coils of the armature.
