    • A Knowledge-Based Engineering System Framework for the Development of Electric Machines 

      Rivera Torres, Christian Alejandro (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2019)
      The new concept industry 4.0 is a great opportunity to improve the competitiveness in a global market for small-medium size electric machinery companies. The demand for electric motors have increased in the last decade ...
    • A Requirement Engineering Framework for Electric Motors Development 

      Rivera Torres, Christian Alejandro; Poza Lobo, Francisco Javier; Ugalde Rosillo, Gaizka; Almandoz Larralde, Gaizka (MDPI AG, 2018)
      The applications using electric motors have increased in the last decade. Some of these applications encounter the need for tailor-made motors that must meet demanding requirements. Therefore, the specification stage of ...
    • DC-Link Voltage and Catenary Current Sensors Fault Reconstruction for Railway Traction Drives 

      Garramiola Aldai, Fernando; Del Olmo, Jon; Poza Lobo, Francisco Javier; Madina Hernández, Patxi; Almandoz Larralde, Gaizka (MDPI AG, 2018)
      Due to the importance of sensors in control strategy and safety, early detection of faults in sensors has become a key point to improve the availability of railway traction drives. The presented sensor fault reconstruction ...
    • Direct control strategy for PMSMS in railway traction application 

      Calleja Elcoro, Carlos (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2013)

    • Effects of manufacturing tolerances of permanent magnets in fractional slot permanent magnet synchronous machines 

      Zarate Barriga, Sergio; Almandoz Larralde, Gaizka; Ugalde Rosillo, Gaizka; Poza Lobo, Francisco Javier (IET, 2019)
      The fractional slot permanent magnet synchronous machines are well-known for their low torque ripple. However, in mass-production machines, not all the permanent magnets are identical due to the manufacturing tolerances ...
    • Field Weakening Characteristics Computed with FEM-Coupled Algorithms for Brushless AC Motors 

      Rivera Torres, Christian Alejandro; Almandoz Larralde, Gaizka; Ugalde Rosillo, Gaizka; Poza Lobo, Francisco Javier (MDPI AG, 2018)
      Finite Element Method (FEM) analysis tools are the most adopted in the design of brushless alternating current motors due to the advantage of considering multi-physics effects with dependencies of variables such as ...
    • Hardware-in-the-loop performance analysis of a railway traction system under sensor faults 

      Garramiola Aldai, Fernando; Poza Lobo, Francisco Javier; Olmo Larrañaga, Jon del (IET, 2019)
      Fault mode and effects analysis (FMEA) has been used during decades for analysing the effects of faults in different applications. Initially, FMEA based on risk priority numbers provided information about the effects in ...
