    • Design Of Pump Shaft Trains Having Variable-Speed Electric Motors 
      Frei, Arno; Grgic, Andrej; Heil, Werner; Luzi, Armin (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
      With converter-fed variable speed electric motors, pulsating torques inevitably occur in the air gap and can cause torsional oscillation in the whole shaft line. The origin and behavior of these torques and how to calculate ...
    • Large Converter-Fed Adjustable Speed AC Drives For Turbomachines. 
      Grgic, Andrej; Heil, Werner; Prenner, Herbert (Texas A&M University. Turbomachinery Laboratories, 1992)
      Converter-fed adjustable speed electric motors are now finding increasing use for driving turbomachinery in the power range from 1.0 to 20 (50) MW. The most important properties of these drives are explained, with the main ...
