Working Principle
Embark on an extraordinary journey of unmatched innovation with our groundbreaking, durable permanent magnet VFD screw air compressor system. A true engineering marvel, it redefines excellence with cutting-edge pressure sensors that meticulously monitor real-time conditions, seamlessly tracking air consumption. By harnessing the precision of electronic and frequency converter controls, the system effortlessly modulates motor speed while maintaining constant motor torque. This flawless operation ensures optimal system pressure, perfectly aligning with the desired compressed air output. When air demand diminishes below output, the intelligent inverter air compressor gracefully decelerates, conserving energy and minimizing output. Conversely, as demand escalates, the system accelerates motor speed, amplifying compressed air supply and ensuring consistent system pressure stability for unparalleled performance.
Unlock the extraordinary potential of our state-of-the-art compressor unit, empowered by advanced vector control technology. This cutting-edge approach delivers impressive efficiency across varying operational speeds while precisely managing motor temperature rise, ensuring peak torque and flawless air compressor operation. Through vector control, the motor's current harmoniously interacts with torque and other values, expertly refined to handle voltage fluctuations at the motor's terminals. This sophisticated methodology achieves peak torque output without increasing current levels, guaranteeing superior performance and unmatched reliability in every application.
