Working Principle
Unveil the excellence of our cutting-edge permanent magnet frequency conversion air compressor, a marvel of modern engineering. Equipped with an ultra-sensitive pressure sensor, it meticulously assesses the actual pressure and air usage of your system. This sensor, combined with a precise electric frequency converter, skillfully adjusts motor speed while maintaining torque, ensuring a reliable and efficient delivery of compressed air tailored to your exact needs. As air consumption decreases, the system gracefully reduces motor speed, minimizing compressed air output and boosting efficiency. Conversely, increased air demand prompts a smooth motor speed acceleration, maintaining optimal system pressure seamlessly.
Our compressors harness the power of advanced vector control technology to deliver unmatched efficiency across a wide range of speeds. This sophisticated technology minimizes motor temperature rise and ensures impeccable torque for flawless operations. By intelligently managing motor current into torque and auxiliary components, these vector control techniques adeptly respond to voltage drops at the motor's end, optimizing torque output without increasing current. This safeguards your equipment and guarantees exceptional performance every time.
