Working Principle
Embark on a transformative journey of unparalleled innovation with our Efficient Energy-Saving Permanent Magnet VFD Screw Air Compressor System. This technological masterpiece, at the forefront of modern engineering, is equipped with advanced pressure sensors that precisely monitor real-time pressure and air consumption. Utilizing the sophistication of electronic and frequency converter controls, the system masterfully adjusts motor speed while maintaining the motor's torque consistently. This seamless adaptation ensures the optimal regulation of system pressure, perfectly aligned with the desired compressed air output levels. When demand falls below the compressor's output, the sophisticated inverter air compressor conserves energy by elegantly reducing its speed while decreasing compressed air output. Conversely, during demand surges, the system accelerates motor speed to boost the compressed air supply, maintaining unwavering consistency of system pressure.
Unleash the extraordinary potential of vector control technology in our advanced compressor unit, which offers remarkable efficiency across a wide range of speeds while minimizing motor temperature rise. This assurance of optimal torque guarantees seamless air compressor operation. The motor's current, a harmonious blend of torque and supplementary values, is ingeniously optimized through vector control technology. These techniques skillfully manage voltage fluctuations at the motor's terminal, allowing for peak torque output without increasing current levels, thus ensuring superior performance and reliability.
