    • Hysteresis loss in NdFeB Permanent Magnets in a Permanent-Magnet-Synchronous Machine 

      Egorov, Dmitry; Petrov, Ilya; Pyrhönen, Juha; Link, Joosep; Stern, Raivo; Sergeant, Peter; Sarlioglu, Bulent (IEEE, 14.01.2021)
      Most permanent-magnet (PM) loss studies consider only eddy current loss and neglect hysteresis. In this paper, the hysteresis behavior of two NdFeB PM grades with different magnetic properties is assessed when applied in ...

    • Hysteresis Losses in Sintered NdFeB Permanent Magnets in Rotating Electrical Machines 

      Pyrhönen, Juha; Ruoho, Sami; Nerg, Janne; Paju, Martti; Tuominen, Sampo; Kankaanpää, Harri; Stern, Raivo; Boglietti, Aldo; Uzhegov, Nikita (2015)
      Permanent magnet materials are nowadays widely used in the electrical machine manufacturing industry. Eddy current loss models of permanent magnets used in electrical machines are frequently discussed in research papers. ...
