Working Principle
Unveil the ingenuity of our permanent magnet frequency conversion air compressor system. This cutting-edge system is outfitted with sophisticated pressure sensors, astutely monitoring real-time pressure and air consumption within its environment. Utilizing precise electronic and frequency converter controls, it adeptly adjusts motor speed while unwaveringly sustaining motor torque. This ensures seamless synchronization of system pressure with the required compressed air output. In instances where air consumption wanes and compressor output surpasses demand, the intelligent inverter air compressor astutely lowers its speed, thus conserving energy by minimizing compressed air output. Conversely, as demand escalates, the system accelerates the motor speed, amplifying compressed air supply, thereby guaranteeing consistent stability in system pressure.
Experience the prowess of state-of-the-art vector control technology with our advanced unit, delivering exceptional efficiency across a diverse range of speeds while concurrently limiting motor temperature rise. This assures optimal torque, enabling smooth operation of the air compressor. The motor's current is a blend of torque and other variables, ingeniously optimized through vector control technology. Notably, vector control methods expertly tackle voltage discrepancies at the motor's end, allowing for maximum torque output without increasing current levels, thus ensuring peak performance and dependability.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
