Abstract: An annular rotating armature is presented. The annular rotating armature includes an armature winding having a plurality of coils, an armature support structure and a magnetic shield disposed between the armature winding and the armature support structure. The magnetic shield having a first magnetic shield ring, a second magnetic shield ring disposed concentric to the first magnetic shield ring and coupled to the first magnetic shield ring via a magnetic shield bridge link. An air gap is formed between the first magnetic shield ring and the second magnetic shield ring. The magnetic shield bridge link is disposed within the air gap. A superconducting generator including the annular rotating armature and a wind turbine having such superconducting generator are also presented.

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.
