Working Principle
Step into the future with our cutting-edge permanent magnet frequency conversion air compressor, a marvel of modern engineering distinguished by its ultra-sensitive pressure sensor. This advanced sensor offers an exact measurement of your system's pressure and air usage. Utilizing an electric frequency converter for immaculate control, it finely adjusts motor speed while preserving torque, ensuring stable and reliable system pressure throughout. The result is a perfectly tailored delivery of compressed air, precisely aligned with your demands. As air usage decreases, the motor speed gracefully descends, lowering air output and boosting efficiency. Conversely, an uptick in air demand sees a seamless increase in motor speed, maintaining a constant system pressure with grace and precision.
Powered by advanced vector control technology, our compressors set new standards for efficiency across a wide range of speeds. This technology expertly minimizes motor temperature rise, ensuring impeccable torque for smooth and seamless operations. By adeptly managing motor current, dividing it into torque and auxiliary components, these state-of-the-art vector control techniques skillfully handle voltage drops at the motor's end, optimizing torque output without increasing current. This not only protects your equipment but also delivers unrivaled performance.
