Working Principle
Unveil the groundbreaking technology of our permanent magnet frequency conversion air compressor system. Outfitted with state-of-the-art pressure sensors, it astutely tracks real-time usage pressure and air consumption within its ecosystem. Utilizing cutting-edge electronic and frequency converter controls, this sophisticated system meticulously adjusts the motor speed while consistently preserving the motor's torque. This ensures a flawless regulation of system pressure, precisely synchronized with the required compressed air output. In instances where air consumption decreases and the compressor's output surpasses demand, the intelligent inverter air compressor gracefully reduces its speed, thereby conserving energy by lowering the compressed air output. Conversely, as demand intensifies, the system accelerates the motor speed, enhancing the compressed air supply, ensuring steadfast stability in system pressure.
Unleash the potential of advanced vector control technology with our unit, providing unmatched efficiency across a wide range of speeds, while effectively suppressing motor temperature rise. This guarantees optimal torque, enabling the seamless operation of the air compressor. The motor's current, comprising torque and other variables, is deftly optimized through vector control technology. Notably, vector control methods adeptly address voltage discrepancies at the motor's end, maximizing torque output without escalating current levels, ensuring peak performance and unwavering reliability.
