Working Principle
Embark on a journey of unmatched innovation with our permanent magnet frequency conversion air compressor system. This technological marvel, a true testament to modern engineering, is equipped with state-of-the-art pressure sensors diligently monitoring real-time pressure and air consumption. By masterfully leveraging the precision of electronic and frequency converter controls, the system skillfully adjusts motor speed while steadfastly maintaining the motor's torque. This seamless adaptation ensures optimal regulation of system pressure perfectly aligned with the desired compressed air output. If air demand decreases below the compressor's output, the intelligent inverter air compressor gracefully slows its pace, conserving energy and reducing compressed air output. In contrast, when demand surges, the system accelerates motor speed to boost the compressed air supply, assuring the unwavering constancy of system pressure.
Unleash the extraordinary capabilities of vector control technology in our advanced compressor unit, delivering remarkable efficiency across a spectrum of speeds while minimizing motor temperature rise. This assurance of optimal torque guarantees the seamless operation of the air compressor. The motor's current, a harmonious blend of torque and additional values, is ingeniously optimized through vector control technology. These techniques adeptly manage voltage fluctuations at the motor's terminal, facilitating peak torque output without escalating current levels, thus ensuring superior performance and reliability.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
