Working Principle
Embark on a transformative journey of unparalleled innovation with our Efficient Energy-Saving Permanent Magnet VFD Screw Air Compressor System. A true marvel of modern engineering, this system is equipped with cutting-edge pressure sensors that meticulously monitor real-time pressure and air consumption. Harnessing the precision of electronic and frequency converter controls, it expertly adjusts motor speed while maintaining consistent torque. This adaptive prowess ensures optimal regulation of system pressure, perfectly synchronized with the desired compressed air output. When demand falls below the compressor's capacity, the sophisticated inverter air compressor conserves energy by gracefully reducing speed and decreasing air output. Conversely, during periods of increased demand, the system accelerates motor speed to enhance compressed air supply, ensuring unwavering consistency of system pressure.
Unleash the extraordinary potential of vector control technology with our advanced compressor unit, offering remarkable efficiency across various 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 additional values, is ingeniously optimized through vector control technology. These techniques expertly manage voltage fluctuations at the motor's terminal, allowing peak torque output without increasing current levels, thus ensuring superior performance and reliability.
