Working Principle
Discover the brilliance of our state-of-the-art permanent magnet frequency conversion air compressor, masterfully crafted with an ultra-sensitive pressure sensor. This sensor precisely measures the actual pressure and air usage within your system. Imbued with precise control through an electric frequency converter, it meticulously fine-tunes motor speed while upholding torque, thus ensuring reliable system pressure. This results in the delivery of compressed air precisely tuned to meet your demands. As air consumption diminishes, the system gracefully decreases motor speed, reducing compressed air output and enhancing efficiency. Conversely, an increase in air consumption prompts a smooth acceleration in motor speed, maintaining stable system pressure continuously.
Our compressors, powered by sophisticated vector control technology, operate with unparalleled efficiency across an impressive spectrum of speeds. This technology minimizes motor temperature rise and ensures flawless torque for seamless operations. It expertly manages motor current by dividing it into torque and auxiliary components. These advanced vector control techniques respond adeptly to voltage drops at the motor's end, maximizing torque output without increasing current, safeguarding your equipment while delivering unmatched performance.
