  • Multiobjective optimization of IPM synchronous motor using response surface methodology and filtered Monte Carlo approach 

    Seifert, Robert; Bargalló Perpiñá, Ramón (2014)
    Conference lecture
    Open Access
    Permanent Magnet Synchronous Motors offer high efficiency and power density besides low assembly effort and hence have been established in a wide market over the past years. Especially buried magnets enable a superior field ...
  • Burden resistor selection in current transformers for low power applications 

    Conesa Roca, Alfons; Bargalló Perpiñá, Ramón; Velasco Quesada, Guillermo; Román Lumbreras, Manuel (Universitat Rovira i Virgili, 2014)
    Conference lecture
    Open Access
    In order to sense AC current with electric isolation in high frequency switching power converters the most simple and low cost solution is to consider a current transformer with a burden resistor. But burden resistor ...

  • Analysis of PMSM using FE analysis: a didactical approach for EMF determination and cogging torque reduction. 

    Bargalló Perpiñá, Ramón; Sust de Rosselló, Jorge; Morón Romera, Juan; Pujolras, Joan Carles (2012)
    Conference lecture
    Open Access
    FE analysis is a useful technique, but the interpretation of the results are sometimes confuse and dark. In this paper we shown some methods to determine the back emf in PMSM and how determine and reduce the cogging torque. ...
