    • Detection of inter-turn faults in five-phase permanent magnet synchronous motors 

      Saavedra Ordóñez, Harold; Riba Ruiz, Jordi-Roger; Romeral Martínez, José Luis (2014-11-27)
      Article
      Accés obert
      Five-phase permanent magnet synchronous motors (PMSMs) have inherent fault-tolerant capabilities. This paper analyzes the detection of inter-turn short circuit faults in five-phase PMSMs in their early stage, i.e. with ...

    • Detection of inter-turns short circuits in permanent magnet synchronous motors operating under transient conditions by means of the zero sequence voltage 

      Urresty Betancourt, Julio César; Riba Ruiz, Jordi-Roger; Saavedra Ordóñez, Harold; Romeral Martínez, José Luis (2011)
      Text en actes de congrés
      Accés obert
      This work proposes the zero sequence voltage component (ZSVC) of the stator three-phase voltages as a method for detecting winding inter-turns short circuits in permanent magnet synchronous motors PMSM operating under ...

    • Detection of interturn faults in PMSMs with different winding configuration 

      Saavedra Ordóñez, Harold; Urresty Betancourt, Julio César; Riba Ruiz, Jordi-Roger; Romeral Martínez, José Luis (2014-03-03)
      Article
      Accés restringit per política de l'editorial
      Interturn faults in permanent magnet synchronous motors (PMSMs) may develop fast into more severe faults such as coil-to-coil, phase-to-phase and phase-to-ground short circuits. These faults are very destructive and may ...

    • Efficiency evaluation of five-phase outer- rotor fault-tolerant BLDC drives under healthy and open-circuit faulty conditions 

      Salehi Arashloo Arashloo, Ramin; Salehifar, Mehdi; Saavedra Ordóñez, Harold; Romeral Martínez, José Luis (2014)
      Article
      Accés obert
      Fault tolerant motor drives are an interesting subject for many applications such as automotive industries and wind power generation. Among different configurations of these systems, five-phase BLDC drives are gaining more ...

    • Inter-turn fault detection in five-phase PMSMs. Effects of the fault severity 

      Saavedra Ordóñez, Harold; Riba Ruiz, Jordi-Roger; Romeral Martínez, José Luis (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper deals with the effects of inter-turn short circuit faults in five-phase permanent magnet synchronous motors (PMSMs). For this purpose a finiteelements model (FEM) of a faulty machine with 1, 2 and 4 inter-turns ...

    • Magnet shape influence on the performance of AFPMM in a torus configuration 

      Saavedra Ordóñez, Harold; Riba Ruiz, Jordi-Roger; Hernández Guiteras, Joan; Romeral Martínez, José Luis (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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 ...

    • Magnet shape influence on the performance of AFPMM with demagnetization 

      Saavedra Ordóñez, Harold; Riba Ruiz, Jordi-Roger; Romeral Martínez, José Luis (IEEE Industrial Electronics Society, 2013)
      Text en actes de congrés
      Accés obert
      In this paper the effect of the magnets shape on the AFPMM performance under a demagnetization fault has been analyzed by means of 3D-FEM simulations. Demagnetization faults in permanent magnet synchronous motors (PMSMs) ...
