ZFeng 900 Series 90Kw-T-G General Vector Variable Frequency Drive

• Vector control technology: By measuring and controlling the stator current vector of asynchronous motors, independent control of motor torque and magnetic field is achieved, improving speed regulation accuracy and dynamic response performance.
• Direct Torque Control (DTC): Control the motor directly in the stator coordinate system, without the need for complex vector transformations, with fast response speed and high control accuracy.
• Matrix AC-AC frequency conversion technology: eliminates the intermediate DC link, achieves a power factor of 1, sinusoidal input current, and four quadrant operation capability, and improves system power density.
