    • Design and Simulation of High-Speed Rotating Electrical Machinery 

      Kurvinen, Emil
      Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 22.01.2016)
      Global energy consumption has been increasing yearly and a big portion of it is used in rotating electrical machineries. It is clear that in these machines energy should be used efficiently. In this dissertation the aim ...

    • Effects of unbalanced magnetic pull on rotordynamics of electric machines 

      Kim, Heesoo
      Acta Universitatis Lappeenrantaensis (Lappeenranta-Lahti University of Technology LUT, 21.05.2021)
      The unbalanced magnetic pull (UMP) that results from air-gap eccentricity can present a potential risk to the lifetime and dynamic stability of rotating electric machines. Nevertheless, a method to identify the effects of ...
