Working Principle
Our revolutionary permanent magnet frequency conversion air compressor features an ultra-sensitive pressure sensor that meticulously tracks actual system pressure and air usage. With precise control delivered by an electric frequency converter, it exquisitely adjusts motor speed while maintaining torque, ensuring consistent system pressure. This enables the perfect synchronization of compressed air delivery with demand. As air consumption decreases, the system intuitively decelerates the motor, thereby reducing compressed air output while enhancing efficiency. Conversely, when air consumption spikes, the motor speed gracefully accelerates, maintaining steady system pressure consistently.
By utilizing cutting-edge vector control technology, our compressor achieves extraordinary efficiency across a vast speed range, minimizing motor temperature increase and ensuring seamless torque delivery. Vector control techniques deftly manage the motor current, split into torque and auxiliary phases, to adeptly respond to voltage drops at the motor end. This maximizes torque output without increasing the current, safeguarding your equipment and guaranteeing unparalleled performance.
