Working Principle
Embark on a remarkable journey of unrivaled innovation with our state-of-the-art permanent magnet frequency conversion air compressor system. This technological marvel is a testament to modern engineering prowess. Equipped with cutting-edge pressure sensors, it diligently monitors real-time pressure and precisely tracks air consumption. By leveraging electronic and frequency converter controls, the system finely tunes motor speed while maintaining the motor's torque. This seamless adaptation ensures optimal regulation of system pressure, harmonized with the desired compressed air output. Should air demand decrease below the compressor's output, the intelligent inverter air compressor reduces its speed, conserving energy and minimizing compressed air output. Conversely, when demand skyrockets, the system accelerates motor speed to amplify the compressed air supply, ensuring unwavering constancy of system pressure.
Unleash the extraordinary capabilities of our advanced compressor unit featuring cutting-edge vector control technology. This technology delivers remarkable efficiency across diverse speeds while minimizing motor temperature rise, assuring optimal torque for seamless air compressor operation. The motor's current, a harmonious combination of torque and additional values, is optimized through vector control technology. These advanced techniques manage voltage fluctuations at the motor's terminal, facilitating peak torque output without escalating current levels, ensuring superior performance and unparalleled reliability.
