Working Principle
Step into a realm of extraordinary innovation with our durable permanent magnet VFD screw air compressor system. This engineering marvel sets new standards of excellence with cutting-edge pressure sensors that meticulously monitor conditions in real-time. These sensors efficiently track air consumption, providing unparalleled insight and control. By utilizing the precision of electronic and frequency converter controls, the system seamlessly adjusts motor speed to maintain consistent motor torque, thereby ensuring optimal system pressure. This pressure alignment perfectly matches the desired compressed air output. When air demand falls below the output levels, the intelligent inverter air compressor smoothly decelerates, effectively conserving energy and reducing output. As demand increases, the system accelerates motor speed, thereby elevating compressed air supply and ensuring pressure stability for outstanding performance.
Unleash the full potential of our advanced compressor unit, powered by cutting-edge vector control technology. This pioneering technology ensures exceptional efficiency across various operational speeds while precisely managing motor temperature rise, guaranteeing peak torque and flawless air compressor operation. With vector control, the motor's current harmoniously balances torque with other values, expertly refined to manage voltage fluctuations at the motor's terminals. This sophisticated approach achieves peak torque output without increasing current levels, ensuring superior performance and unmatched reliability in every application.
