Working Principle
Embark on an extraordinary journey of unmatched innovation with our groundbreaking durable permanent magnet VFD screw air compressor system. This engineering masterpiece redefines excellence with its state-of-the-art pressure sensors that meticulously monitor real-time conditions and seamlessly track air consumption. By harnessing the precision of electronic and frequency converter controls, the system effortlessly adjusts motor speed while maintaining constant motor torque. This flawless modulation ensures optimal system pressure, perfectly aligning with the desired compressed air output. When air demand decreases below output, the intelligent inverter air compressor smoothly decelerates, conserving energy and reducing output. Conversely, as demand rises, the system accelerates motor speed, elevating compressed air supply and ensuring consistent system pressure stability for unparalleled performance.
Unlock the extraordinary potential of our state-of-the-art compressor unit, powered by advanced vector control technology. This technology delivers outstanding efficiency across a range of operational speeds while precisely managing motor temperature rise, ensuring peak torque and flawless air compressor operation. Through vector control, the motor's current harmoniously combines torque and other values, expertly refined to manage voltage fluctuations at the motor's terminals. This sophisticated approach achieves peak torque output without increasing current levels, guaranteeing superior performance and unmatched reliability in every application.
