Failure Analysis of Induction Motors: Magnetic Wedges in Compression Stations

  title={Failure Analysis of Induction Motors: Magnetic Wedges in Compression Stations},
  author={R A Hanna and Dennis W. Schmitt},
  journal={IEEE Industry Applications Magazine},
This article presents the failure analysis and field measurements of five 7,500-hp induction motors driving reciprocating compressors for a natural gas compression station. The failure analysis examined fan design, vibration, motor-operating temperature, compressor loading profile, number of motor starts, and ambient temperature. A comparison between direct online motor starting and soft starting using an adjustable speed drive (ASD) and the impact on motor performance are presented. The… CONTINUE READING
