Working Principle
Embark on an unparalleled journey of groundbreaking innovation with the Exceptional Energy-Saving Permanent Magnet VFD Screw Air Compressor System. This technological marvel exemplifies the pinnacle of modern engineering with state-of-the-art pressure sensors that meticulously monitor real-time pressure and air consumption. Utilizing cutting-edge electronic and frequency converter controls, the system deftly adjusts motor speed while maintaining consistent motor torque. This harmonious synchronization ensures optimal regulation of system pressure, perfectly aligning with the desired compressed air output. When air demand decreases below the compressor's output, the intelligent inverter air compressor elegantly conserves energy by reducing its pace and lowering compressed air output. On the other hand, when demand increases, the system accelerates motor speed to boost compressed air supply, ensuring constant and unwavering system pressure.
Unlock the extraordinary potential of vector control technology within our state-of-the-art compressor unit, delivering unmatched efficiency across a diverse range of speeds while minimizing motor temperature rise. This ensures optimal torque for the seamless operation of the air compressor. The motor's current, a perfect blend of torque and additional values, is ingeniously optimized through advanced vector control technology. These sophisticated techniques expertly manage voltage fluctuations at the motor's terminal, allowing peak torque output without an increase in current levels, thereby guaranteeing superior performance and unwavering reliability.
