Abstract :
In recent years, Ansaldo Industria SpA and Ross Hill Controls Corp. developed a series of large-power, variable speed drives with induction motors suitable for the direct driving of high-speed fluidodynamic machines. The most significant field of application is the pipeline industry, where the variable speed drives are generally used for peak service of gas compression stations located close to highly populated areas. The paper covers the authors´ experience in designing, manufacturing and testing large-power, high-speed induction motors. Reference is made to the drive systems already tested and commissioned: two rated at 5250 kW, 3200 to 5500 RPM and two rated at 6600 kW, 2400 to 5200 RPM; all installed in the USA
