Working Principle
Embark on a journey of innovation with our permanent magnet frequency conversion air compressor system. This marvel of modern engineering is outfitted with sophisticated pressure sensors that meticulously track real-time pressure and air consumption. By harnessing the precision of electronic and frequency converter controls, the system adeptly adjusts motor speed while ensuring the motor's torque remains constant. This harmonious adjustment ensures optimal regulation of system pressure aligned with the required compressed air output. When air demand falls below the compressor's output, the intelligent inverter air compressor elegantly reduces its speed, thus conserving energy and reducing compressed air output. Conversely, when demand rises, the system expedites the motor speed to amplify the compressed air supply, guaranteeing the stable constancy of system pressure.
Unleash the prowess of vector control technology in our advanced unit, delivering exceptional efficiency across varied speeds while limiting motor temperature increase. This promise of optimal torque ensures the smooth operation of the air compressor. The motor's current, a blend of torque and additional values, is ingeniously fine-tuned through vector control technology. Vector control techniques expertly manage voltage fluctuations at the motor's terminal, facilitating maximum torque output without increasing current levels, thus securing top-tier performance and dependability.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
