    • Combined Torsional And Electromechanical Analysis Of An Lng Compression Train With Variable Speed Drive System. 
      Rotondo, Paola; Andreo, Davide; Falomi, Stefano; Jörg, Pieder; Lenzi, Andrea; Hattenbach, Tim; Fioravanti, Duccio; De Franciscis, Sergio (Texas A&M University. Turbomachinery Laboratories, 2009)
      Nowadays variable speed drive systems (VSDS) are preferred to constant speed drives in the oil and gas industry because they can improve the efficiency of the process while avoiding the use of complex mechanical mechanisms ...
    • Comparison Of Two- And Four-Pole Vsd Motors Up To 4000 RPM 
      Holopainen, Timo P.; Liukkonen, Olli; Jörg, Pieder (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      Electric motors were originally developed for Directly-on-Line (DOL) operation. The speed of a motor was determined by the number of poles. A two-pole motor was used to reach 3600 rpm with 60 Hz grid frequency, and the ...
