Abstract
A gas turbine engine assembly includes an electromagnetic machine for extracting power from the turbine engine. The electromagnetic machine includes an outer rotor and an inner rotor rotatably supported adjacent to a stator disposed between the inner and outer rotors. The stator has an inner set of windings disposed on an inner surface adjacent to the inner rotor, and an outer set of windings on an outer surface of the stator adjacent to the outer rotor. The inner stator windings form a set of multiple-phase windings, and the outer stator windings form a set of multiple-phase windings.
