• Design optimization of ironless multi-stage axial-flux permanent magnet generators for offshore wind turbines 

      Zhang, Zhaoqiang; Nilssen, Robert; Muyeen, S.M.; Nysveen, Arne; Al-Durra, Ahmed (Journal article; Peer reviewed, 2017)
      Direct-driven ironless-stator machines have been reported to have low requirements on the strength of the supporting structures. This feature is attractive for offshore wind turbines, where lightweight generators are ...
    • Multiphysics 3D Modelling of Ironless Permanent Magnet Generators 

      Zhang, Zhaoqiang; Muyeen, S.M.; Al-Durra, Abel A.; Nilssen, Robert; Nysveen, Arne (Journal article; Peer reviewed, 2014)
      Abstract Analytical method is widely used for the preliminary design and optimization of electrical machines. It has short calculation time and low computational cost (cost of simulation codes and supporting hardware), but ...
