      Article
      Accés restringit per política de l'editorial
      This work presents a range optimization of a SynRM (synchronous reluctance motor) and a PMaSynRM (permanent-magnet-assisted synchronous reluctance motor) according to a standard driving cycle, and the solutions obtained ...
    • Detection of eccentricity faults in five-phase ferrite-PM assisted synchronous reluctance machines 

      López Torres, Carlos; Riba Ruiz, Jordi-Roger; García Espinosa, Antonio; Romeral Martínez, José Luis (Multidisciplinary Digital Publishing Institute, 2017-05-31)
      Article
      Accés obert
      Air gap eccentricity faults in five-phase ferrite-assisted synchronous reluctance motors (fPMa-SynRMs) tend to distort the magnetic flux in the air gap, which in turn affects the spectral content of both the stator currents ...
