Working Principle
Discover the pinnacle of innovation with our state-of-the-art permanent magnet frequency conversion air compressor. It ingeniously employs an ultra-sensitive pressure sensor that instantly gauges the real-time pressure and air usage within your system. Empowered by a precision electric frequency converter, it dynamically adjusts motor speed while maintaining consistent torque, effectively stabilizing system pressure. This seamless process ensures that compressed air delivery perfectly aligns with actual demand. As air consumption declines, the system smartly reduces motor speed, trimming compressed air output and boosting energy efficiency. Conversely, when air consumption surges, the motor speed increases, guaranteeing unwavering system pressure at all times.
Harnessing the power of cutting-edge vector control technology, our unit delivers exceptional efficiency across a vast range of speeds, minimizing motor temperature rise and ensuring optimal torque for smooth operation. The motor current, thoughtfully divided into torque and additional components, is expertly managed by advanced vector control techniques. These techniques adeptly adapt to voltage drops at the motor end, optimizing torque output without increasing current, thereby protecting your equipment while ensuring superior performance.
