Working Principle
Delve into the intricate workings of our permanent magnet frequency conversion air compressor, which smartly adapts to real-time pressure and air consumption demands. Utilizing a high-tech pressure sensor and precision-controlled electric frequency converter, it dynamically adjusts motor speed while maintaining torque, ensuring a seamless, demand-driven supply of compressed air. When air consumption drops, the compressor intuitively reduces speed to curtail air output, and conversely, ramps up speed when demand rises, consistently maintaining stable system pressure.
Harnessing the power of advanced vector control technology, our unit operates efficiently across a broad speed spectrum. This ensures minimal motor temperature rise while delivering optimal torque for smooth compressor operation. By precisely regulating the motor's current, vector control distributes current values to maximize torque output without necessitating increased current, even compensating for voltage drops at the motor end.
