    • Advanced Uncertainty Calculation Method for Converter-Fed Motor Loss Determining 

      Kärkkäinen, Hannu; Aarniovuori, Lassi; Niemelä, Markku; Pyrhönen, Juha (IEEE, 05.08.2019)
      There is only a single practical method to determine the losses of converted-fed electrical machines. The method is based on mechanical output and electrical input power measurements. When this method is used, the loss ...

    • The Instrumentation Influence on the Motor Loss Determination Uncertainty 

      Kärkkäinen, Hannu; Aarniovuori, Lassi; Niemelä, Markku; Pyrhönen, Juha (IEEE, 09.12.2019)
      The input-output method is the most frequently used and, in practice, the only viable alternative to determine the losses of all electrical machines regardless of the supply type or motor technology. However, the losses ...
