The motor flux model is based on measurements of all three output currents and the voltage as given by the ASIC circuit. The model automatically identifies motor parameters for both the sensorless vector mode and the U/f mode, keeping track of changes in the parameters over time. The vector control is carried out in a system of stator flux coordinates, which is immune to small variations in measurements and motor parameters.]]> Thu, 28 Feb 2008 00:00:00 +0200 http://www.au.all.biz/g883/ http://www.au.all.biz/g889/ NFX9000 adjustable frequency AC Drives from Eaton’s electrical business are designed to provide adjustable speed control of three-phase motors. These microprocessor- based drives have standard features that can be programmed to tailor the drive’s performance to suit a wide variety of application requirements.]]> Thu, 28 Feb 2008 00:00:00 +0200 http://www.au.all.biz/g889/
