A machine includes a stator assembly that includes a stator yoke, a pair of armature coils mechanically coupled to the stator yoke, and a stationary superconducting field coil. The stator yoke comprises a magnetic material. The machine further includes a shaft rotatably mounted in the stator yoke, the shaft comprising a non-magnetic material. The machine further includes a rotor assembly rotationally engaged with the shaft. The rotor assembly includes a rotor disk extending between the armature coils, the rotor disk having an inner portion and an outer portion. The outer portion of the rotor disk includes a number of circumferentially-spaced, magnetic poles. The rotor disk is coupled to the shaft for rotation about the shaft and generation of a rotating permeance wave. The stationary superconducting field coil is disposed between the stator yoke and the rotor disk, and the stationary superconducting field coil is configured as a stationary magneto-motive force (MMF) source for the rotating permeance wave produced by the rotor assembly to produce a rotating magnetic field.
