Introduction
An AC drive is a device that is used to control the speed of an electrical motor, either an induction motor or a synchronous motor. AC drives are also known by various other names such as adjustable speed drives (ASD) or adjustable frequency drives (AFD) or variable frequency drives (VFD) or variable speed drives (VSD) or frequency converters (FC). 
The speed is controlled by changing the frequency of the electrical supply to the motor. The 3-phase voltage in the national electrical grid connected to a motor creates a rotating magnetic field in the motor. The rotor of the electrical motor follows this rotating magnetic field. An AC drive converts the frequency of the network to anything from 0 up to 300 Hz or even higher, and thus controls the speed of the motor in proportion to the frequency.

Technical feature

• Sensorless Vector control frequency inverter with high performance, excellent quality and low pollution.

• 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.

• Advanced processing technique and perfect testing equipment, which guarantees the applicable reliability.
