    The axial flux permanent magnet machine (AFPMM)is being increasingly demanded for special applications, particularly for transportation systems and concretely for inwheel applications. In this paper the effect of the magnets ...
  • Redesign process of a 765 kV AC substation connector by means of 3D-FEM simulations 

    Hernández Guiteras, Joan; Riba Ruiz, Jordi-Roger; Romeral Martínez, José Luis (2014-03-03)
    Article
    Restricted access - publisher's policy
    This paper shows the capabilities of applying the three-dimensional finite element method (3D-FEM) for designing complex-shaped substation connectors to operate at 765 kVRMS AC. To check this methodology, it was analyzed ...
