Working Principle
Embark on an extraordinary journey into the realm of innovative excellence with our durable permanent magnet VFD screw air compressor system. This engineering marvel sets new standards with its advanced pressure sensors, which diligently monitor real-time conditions and seamlessly track air consumption. Leveraging sophisticated electronic and frequency converter controls, the system adeptly adjusts motor speed, all while preserving constant motor torque. This exquisite modulation guarantees optimal system pressure, perfectly synchronized with the desired compressed air output. When air demand falls below output levels, the intelligent inverter air compressor gracefully decelerates, conserving energy and minimizing output. Conversely, as demand surges, the system accelerates motor speed, boosting compressed air supply and ensuring consistent system pressure stability for unrivaled performance.
Unlock the extraordinary potential of our state-of-the-art compressor unit, powered by advanced vector control technology. This cutting-edge technology ensures remarkable efficiency across a spectrum of operational speeds while meticulously managing motor temperature rise for peak torque and flawless air compressor operation. Through vector control, the motor's current seamlessly blends torque with other values, expertly refined to handle voltage variations at the motor's terminals. This sophisticated method achieves maximum torque output without boosting current levels, promising exceptional performance and unmatched reliability across all applications.
