Working Principle
Our innovative permanent magnet frequency conversion air compressor masterfully utilizes an ultra-sensitive pressure sensor to accurately and instantaneously measure the real-time pressure and air usage in your system. Through the deft precision of an electric frequency converter, it dynamically modulates motor speed while consistently maintaining torque balance, thereby ensuring a stable system pressure. This guarantees that compressed air delivery is perfectly aligned with current demand. When air consumption decreases, the system astutely reduces motor speed, curtailing compressed air production and significantly boosting energy efficiency. Conversely, a rise in air consumption prompts an increase in motor speed, ensuring stable system pressure is maintained at all times.
By harnessing cutting-edge vector control technology, our unit achieves remarkable efficiency across a broad range of speeds, effectively minimizing motor temperature rise and securing optimal torque for seamless operation. The motor current, strategically divided into essential torque and auxiliary components, is expertly managed by state-of-the-art vector control techniques. These techniques intelligently respond to voltage drops at the motor end, optimizing torque output without increasing current load, thus safeguarding your equipment and guaranteeing superior performance.
