50HP 480V Eaton SVX9000 Series Adjustable Frequency Drive with Brake Chopper Circuit, NEMA 1

AC Drive has compact, modular solution to variable speed applications with sensorless vector control technology coupled with an adaptive motor model and sophisticated ASIC circuit features. 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.
