The SVX9000 is a 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. The sophisticated sensorless flux vector control achieves the dynamic precision of closed loop motor control over most of the speed range:
Steady state speed error: < 0.5%
Torque rise time: < 10 ms
Low ripple in the torque
High immunity to resonance vibrations
High starting torque: 200% (depends on motor/drive sizing)
High starting current: 2.0 x IH
Suitable for multi‑motor drive systems
High‑speed applications, max output frequency 7200 Hz (with special application)
