Working Principle
A permanent magnet frequency conversion air compressor represents the pinnacle of cutting-edge technology with its highly sophisticated pressure sensor. This advanced sensor astutely monitors real-time system pressure and air consumption with precision. By adeptly controlling the electric and frequency converter, the system seamlessly adjusts motor speed, ensuring constant torque of the air compressor motor. This intelligent modulation guarantees that the compressed air output impeccably matches demand at all times. If the system's air consumption dips, the compressor output exceeds requirements, prompting the inverter to gently decrease motor speed, leading to a smooth reduction in air output. Conversely, when air demand spikes, the motor speed escalates, effortlessly increasing air output to maintain consistent system pressure with ease.
Harnessing the power of cutting-edge vector control technology, this compressor operates with remarkable efficiency across a broad spectrum of speeds, minimizing motor temperature rise to its lowest possible level. This groundbreaking technology assures that the motor delivers the necessary torque to drive the air compressor with an unparalleled smoothness. Vector control technology strategically manages the motor current, composed of the torque component generated by the motor, for optimal compensation of voltage drops at the motor's end. This allows for maximum torque output without increasing current use, thereby boosting performance and reliability to new heights.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
The trailblazing frequency conversion regulation significantly reduces the compressor's actual power consumption, ensuring energy is exploited to its utmost potential for air compression. This innovation leads to exceptional energy efficiency and considerable cost savings, cementing the compressor's status as both an environmentally friendly and cost-effective solution.
Cost Reducing
The avant-garde permanent magnet frequency conversion technology slashes energy costs by over 35%, while efficiently trimming the compressor's life cycle cost by about 22%.
