sensorless vector control variable frequency drive (VFD)
Vector control is also known as the "field oriented control", "flux oriented control" or "indirect torque control". Based on this latest motion control theory and technological achievement. PI8100 is sensorless vector control high performance frequency inverter (variable frequency drive). It achieves perfect motor control via servo function, and offers comprehensive drive solution.
Technical feature of this sensorless vector control high performance frequency converter:
1. Sensorless Vector control variable frequency drive (variable speed drive, VSD, VFD) with high performance, excellent quality and low pollution
2. It achieves quick-response and precise control by decoupling control of motor magnetic flux current and torque current, which makes the speed adjustment and torque control runs at a high degree of accuracy and wide range.
3. Reasonable hardware platform, advanced processing technique and perfect testing equipment, which guarantees the applicable reliability
