Monitoring Pump and Compressor Performance Using Motor Data Free

Mechanical condition diagnostics have historically relied upon both human perceptions (sound, sight, smell) and mechanical measurements, such as vibration. In recent years, the ability to extract useful information about certain conditions of mechanical equipment driven by motors from motor energy transfer components (current, power, etc.) has been recognized. This paper discusses the use of motor data to assist in the understanding of certain fluid and mechanical conditions of compressors and pumps.
