Working Principle
Our state-of-the-art permanent magnet frequency conversion air compressor ingeniously employs an ultra-sensitive pressure sensor to instantaneously gauge the actual pressure and air usage within your system. Through the precision of an electric frequency converter, it dynamically adjusts motor speed while maintaining consistent torque, thereby stabilizing system pressure. This ensures that compressed air delivery aligns perfectly with actual demand. When air consumption decreases, the system smartly reduces motor speed, curtailing compressed air output and enhancing energy efficiency. Conversely, an upsurge in air consumption triggers an increase in motor speed, thus guaranteeing stable system pressure at all times.
Leveraging cutting-edge vector control technology, our unit operates with exceptional efficiency across a wide spectrum of speeds, effectively minimizing motor temperature rise and ensuring optimal torque for seamless operation. The motor current, strategically divided into torque and additional components, is adeptly managed by advanced vector control techniques. These techniques intelligently adapt to voltage drops at the motor end, optimizing torque output without increasing current, thereby safeguarding your equipment while ensuring superior performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
