Working Principle
Embark on an extraordinary journey of innovation with our impressive Efficient Energy-Saving Permanent Magnet VFD Screw Air Compressor System. This marvel of modern engineering is equipped with cutting-edge pressure sensors that meticulously monitor real-time pressure and air consumption. Through the ingenious use of advanced electronic and frequency converter controls, it skillfully adjusts motor speed while preserving consistent motor torque. This harmonious operation ensures optimal system pressure regulation, perfectly aligning with the desired compressed air output. When air demand dips below the output, the intelligent inverter air compressor gracefully conserves energy, reducing its pace and lowering compressed air output. Conversely, when demand surges, it accelerates motor speed, boosting the compressed air supply, and ensuring system pressure remains constant and unwavering.
Discover the extraordinary potential of vector control technology in our state-of-the-art compressor unit, which delivers exceptional efficiency across a spectrum of speeds while minimizing motor temperature rise. This ensures optimal torque for seamless air compressor operations. The motor's current, a sophisticated blend of torque and additional values, is ingeniously refined through advanced vector control technology. These techniques expertly manage voltage fluctuations at the motor's terminal, enabling peak torque output without a rise in current levels, thereby guaranteeing superior performance and unwavering reliability.
