    Abstract: An electrical machine includes a stator and a rotor in magnetic communication with the stator. The stator and/or the rotor include a unitary structure having a plurality of laminations and a plurality of spacing structures integral with the plurality of laminations. Each lamination of the plurality of laminations is disposed adjacent to another lamination of the plurality of laminations. Each spacing structure of the plurality of spacing structures is disposed between adjacent laminations, and is constructed to space the adjacent laminations apart from each other.

    Abstract: A synchronous machine and related systems include a stator and rotor separated by an air gap. The rotor includes a rotating DC power supply coupled to exciter windings disposed adjacent the air gap. Power from air gap harmonics, including air gap slot harmonics induce current in the exciter windings, which is rectified and supplied to the rotor field windings. In operation, a desired current level in the rotor field windings can be achieved through control of the DC power supply or superposition of harmonics into the stator winding current which induces the prescribed current in exciter windings.
