Abstract: A motor driven propulsor of an aircraft includes magnets disposed in fan shrouds of fan blades connected with a fan hub, a stator having individual conductive coils in a nacelle located radially outside of the fan hub, and a distributed inverter assembly having several inverter power stages and gate drivers, each of the inverter power stages coupled with a separate gate driver of the gate drivers and a separate coil of the coils in the stator. Each of the gate drivers is configured to individually control supply of direct current to the corresponding inverter power stage. Each of the inverter power stages is configured to convert the direct current supplied to the inverter power stage to an alternating current that is supplied to the corresponding coil in the stator to rotate the magnets and the fan blades around a center line of the fan hub for propelling the aircraft.

Abstract: An electrical machine of a vehicle electrical propulsion system includes a stator, a rotor, and a stator winding all disposed within a housing thereof. The stator defines a central bore elongated along a longitudinal axis, and multiple slots circumferentially disposed around the central bore. The rotor is held within the central bore and rotates relative to the stator. The stator winding includes a core conductor, an insulation layer surrounding the core conductor, and a conductive shield layer surrounding the insulation layer. The stator winding extends through the slots of the stator. The stator winding includes an in-slot portion within the slots of the stator and an end-winding portion outside of the slots. The conductive shield layer surrounds the insulation layer along both the in-slot portion and the end-winding portion of the stator winding.

Abstract: A method includes forming elongated magnetic flux carrier portions in magnetically conductive sheets by cutting elongated magnetic flux barriers including one or more relief features into the magnetically conductive sheets, such that the magnetic flux barriers are separated from each other in radial directions of the magnetically conductive sheets. The method includes inserting or forming non-magnetic posts into the magnetic flux barriers such that each of the non-magnetic posts is elongated in a different radial direction of the radial directions from a first magnetic flux carrier portion to a second magnetic flux carrier portion of the magnetic flux carrier portions on opposite sides of at least one magnetic flux barrier; and forming at least part of a rotor for an electric machine assembly using the magnetically conductive sheets having the magnetic flux carrier portions, the non-magnetic posts, and the magnetic flux barriers.

Abstract: An electric machine assembly includes a rotor formed from one or more magnetically conductive sheets having elongated magnetic flux barriers separated from each other in radial directions that radially extend away from an axis of rotation of the rotor. The magnetic flux barriers are separated from each other by magnetic flux carrier portions of the one or more magnetically conductive sheets. The assembly also includes a non-magnetic post coupled with the magnetic flux carrier portions of the one or more magnetically conductive sheets on opposite sides of at least one of the magnetic flux barriers. The non-magnetic post is elongated in the radial directions from a first magnetic flux carrier portion to a second magnetic flux carrier portion of the magnetic flux carrier portions on the opposite sides of the at least one magnetic flux barrier.
