Working Principle
Introducing our cutting-edge permanent magnet frequency conversion air compressor, ingeniously designed with an ultra-sensitive pressure sensor that instantaneously measures actual pressure and air usage within your system. Through the sophisticated precision of an electric frequency converter, it cleverly adjusts motor speed while consistently maintaining torque, thereby ensuring system pressure stabilization. This intelligent system guarantees that compressed air delivery aligns perfectly with real-time demand. In instances of reduced air consumption, the system smartly decreases motor speed, reducing compressed air output and enhancing energy efficiency. Conversely, during heightened air consumption, it promptly increases motor speed, delivering stable system pressure at all times.
By harnessing the power of cutting-edge vector control technology, our unit achieves remarkable efficiency across a wide range of speeds, effectively minimizing motor temperature rise and ensuring optimal torque for seamless operation. The motor current is strategically divided into torque and additional components, adeptly managed by advanced vector control techniques. These techniques intelligently adapt to voltage drops at the motor end, optimizing torque output without increasing current, thus safeguarding your equipment while guaranteeing superior performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
