Working Principle
Our cutting-edge permanent magnet frequency conversion air compressor is designed with an ultra-sensitive pressure sensor that meticulously measures the actual pressure and air usage within your system. Boasting precise control via an electric frequency converter, it exquisitely fine-tunes motor speed while maintaining torque, ensuring consistent system pressure. This guarantees that compressed air is delivered precisely according to demand. When air consumption decreases, the system intuitively slows down the motor speed, thereby cutting down compressed air output and enhancing efficiency. Conversely, when there's a rise in air consumption, the motor speed gracefully increases, maintaining stable system pressure at all times.
Harnessing the power of advanced vector control technology, our compressor operates with extraordinary efficiency across a vast range of speeds, minimizing motor temperature rise and ensuring exquisite torque for seamless operation. The motor current, split into torque and auxiliary components, is expertly managed by vector control techniques. These techniques adeptly respond to voltage drops at the motor end, maximizing torque output without raising current, thereby protecting your equipment and ensuring unparalleled performance.
