    • Asynchronous Motor - Failure of Rotor Lamination Teeth 
      Coudray, Xavier; Delhaye, Guillaume; Velly, Nicolas; Quoix, Bernard; Gelin, Alain; Lucas, Antoine (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      During full load testing of moto-compressor, abnormal vibration were detected. Failure was observed on electrical motor rotor lamination teeth. Deep experimental analysis and metallurgical investigations revealed a high ...
    • Electric Driven Centrifugal Compressor - Super Synchronous Vibrations of the High Speed Shaft Line: Observations, Assessment and Resolution 
      Seon, Jeremie; Lucas, Antoine; Coudray, Xavier; Gelin, Alain (Texas A&M University. Turbomachinery Laboratories, 2013)
      An unacceptable vibratory behavior was encountered in 2012 during the full load string test of an electric driven centrifugal compressor. The vibrations were observed on the high speed part of the shaft line and both ...
    • High Performance Bearing Comparison 
      Ronan, Josh; Shoup, Thomas; Perney, Gwenael; Robertson, Chad; Quoix, Bernard; Gelin, Alain (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)
      With the increasing demand for high performance gearboxes, larger, faster, more highly loaded bearings are requiring more oil and creating more heat than ever before. This means the lubrication systems must be larger to ...
    • Mechanical And Performance Testing Method Of An Integrated High-Speed Motor Compressor. 
      Alban, Thomas; Pellerin, Olivier; Laboube, Pierre; Quoix, Bernard; Gelin, Alain; Oliva, Matthieu (Texas A&M University. Turbomachinery Laboratories, 2009)
      The integrated electric motocompressor is a recently available technology that has the advantage of drastically simplifying the machine configuration. The use of a high speed electrical motor in the process gas combined ...
    • Moto-Compressor coupling failure 
      Bellocq, Pablo; Gelin, Alain; Thibaut, Edouard (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      This case study will present the failure of the LS coupling of a variable speed moto compressor, due to a resonance of the first critical torsional speed while running at Minimum Operating Speed. The path followed for the ...
    • Sub-Synchronous Vibrations On a Vertical Electrical Motor During Factory Testing Observed Phenomenon, Interpretation and Resolution 
      Quoix, Bernard; Cloud, C. Hunter; Gelin, Alain; He, Minhui (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
    • Subsynchronous Vibrations on a Vertical Electrical Motor During Factory Testing – Observed Phenomenon, Interpretation and Resolution 
      Gelin, Alain; Cloud, C. Hunter; Quoix, Bernard; He, Minhui (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      During the factory tests of a vertical electric driven de-ballasting pump, casing vibrations were observed on the motor above the contractual limit of 2.8 mm/s, mainly on the motor’s top, Non-Drive End. Supported by fluid ...
