Nadhem Boubaker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230126330
    Abstract: An electrical machine for use in an aircraft. The electrical machine includes a rotor that includes a plurality of rotor poles, and a stator including a plurality of phases. Each respective phase occupies at least one elementary block. The at least one elementary block of each phase includes a set of conductors of the respective phase wound around a plurality of slots of the respective elementary block in a concentrated winding configuration. The stator further includes at least one sensor located between two elementary block. The at least one sensor being configured to measure at least one parameter of the rotor.

  • Publication number: 20220140684
    Abstract: An electrical machine for use in an aircraft, including a rotor. The rotor includes a plurality of rotor poles, and a stator including a plurality of phases. Each respective phase occupies at least one elementary block and the at least one elementary block of each phase includes a set of conductors of the respective phase wound around a plurality of slots of the respective elementary block in a concentrated winding configuration. A mechanical shift angle between the respective concentrated windings of each pair of adjacent elementary blocks is greater than a rotor pole pitch. The rotor pole pitch is an angle between adjacent poles of the rotor.

  • Publication number: 20210391777
    Abstract: A generator arranged to be driven by an aircraft engine, the generator comprising a stator and a rotor. The stator comprises a stator core and a plurality of slots longitudinally extending in a direction of a longitudinal axis of the stator, for receiving conductors to form windings of the stator, and a plurality of power channels. Each power channel comprises a set of windings having at least a first phase winding including a first set of coils comprising a plurality of conductors wound in a lap winding configuration, the first set of coils having a split phase belt such that the first set of coils comprises at least a first coil and a second coil, the first coil being mechanically shifted with respect to the second coil by a predetermined number of slots of the stator. The rotor comprises a permanent magnet adapted to reduce eddy-current losses.
