Working Principle
Discover the brilliance of our state-of-the-art permanent magnet frequency conversion air compressor. This engineering marvel is masterfully crafted with an ultra-sensitive pressure sensor that impeccably measures actual pressure and air usage within your system. Enhanced by precise control via an electric frequency converter, it adeptly fine-tunes motor speed, all while maintaining torque, ensuring unwavering system pressure. This sophisticated mechanism delivers compressed air perfectly attuned to your requirements. As air consumption diminishes, the system elegantly reduces motor speed, decreasing compressed air output and augmenting efficiency. Conversely, a rise in air consumption prompts a seamless increase in motor speed, continuously preserving stable system pressure. Revel in the ingenuity of a system that harmonizes efficiency with reliability.
Our compressors, driven by cutting-edge vector control technology, deliver astronomical efficiency across an astonishing range of speeds. This advanced technology not only minimizes motor temperature rise but also guarantees flawless torque for seamless operations. It meticulously manages motor current by partitioning it into torque and auxiliary components. These avant-garde vector control techniques respond brilliantly to voltage drops at the motor's end, optimizing torque output without escalating current. This ensures the safeguarding of your equipment while delivering performance that is second to none. Experience the pinnacle of operational excellence with unparalleled efficiency and reliability.
