Working Principle
Our state-of-the-art permanent magnet frequency conversion air compressor employs an advanced pressure sensor to continuously monitor system pressure and air demand. This intelligent monitoring, combined with precise control mechanisms, dynamically adjusts motor speed without losing torque. Consequently, it fine-tunes the system pressure to meet compressed air requirements efficiently. When air consumption drops and the compressor's output exceeds system needs, the inverter reduces the motor speed, syncing production with consumption to maintain system stability. Conversely, when demand spikes, the motor speed ramps up, ensuring a steady, reliable flow of compressed air.
Leveraging cutting-edge vector control technology, our compressor delivers efficient performance across a broad speed range while minimizing motor temperature increases, ensuring optimal torque and smooth operation. Vector control technology separates motor current into torque-producing components and other values, counteracting voltage drops at the motor end. This advanced mechanism maximizes torque output without increasing current, significantly enhancing operational efficiency.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Savings
Frequency conversion regulation dramatically cuts the actual power consumption of the compressor, ensuring energy is utilized most efficiently for air compression.
Cost Reduction
Our permanent magnet frequency conversion technology slashes energy costs by more than 35%, and the overall lifecycle cost of the compressor decreases by an average of 22%. Typically, the additional investment in the compressor pays for itself within 1 to 2 years.
Stable Pressure
Employing the sophisticated PID (Proportional, Integral, Differential) method, our compressor precisely adjusts to maintain stable system pressure, ensuring consistent and reliable performance.
Extended Lifespan
Frequency conversion startup significantly reduces impact on the power grid and machinery, extensively prolonging the compressor's service life.
