sensorless vector control variable frequency drive (VFD)

الوصف

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
