    • Characterization of a novel counter-rotating twin harmonic PM machine 

      Desmedt, Michiel; Nilssen, Robert Kristoffer; Bergesen, Samson (Chapter, 2023)
      Most machine topologies have two-ports, with one set of electrical connections and one mechanical shaft. Three-port machines having two rotors and mechanical shafts are able to drive two mechanical loads using one stator ...

    • A Static FEA Framework for Fast Analysis of HTS Armature Windings in AC Superconducting SMPM Machines 

      Hartmann, Christian Magnus; Mellerud, Runar; Nøland, Jonas Kristiansen; Nilssen, Robert Kristoffer (Journal article; Peer reviewed, 2023)
      Macroscopic superconductivity models have improved significantly over the last decades. Formulations and methods have been developed to faster solve problems involving high-temperature superconductors (HTS). Despite these ...
