Working Principle
A permanent magnet frequency conversion air compressor utilizes an advanced pressure sensor to promptly gauge system pressure and air demand. This intelligent detection, paired with precise control of the electric and frequency converter, modulates motor speed without diminishing motor torque. Consequently, it fine-tunes system pressure to provide compressed air as required. When air consumption decreases and the compressor's output surpasses system needs, the inverter reduces rotational speed, perfectly aligning production with consumption to maintain system equilibrium. On the contrary, when demand escalates, the motor speed increases, ensuring a consistent flow of compressed air.
Employing state-of-the-art vector control technology, our compressor operates efficiently across a broad speed spectrum while minimizing motor temperature rise, ensuring optimal torque for smooth operation. Vector control technology divides motor current into torque-producing components and other current values, counteracting voltage drops at the motor end. This sophisticated mechanism maximizes torque output without increasing current, thereby enhancing operational efficiency.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Savings
Frequency conversion regulation significantly reduces the actual power consumption of the compressor, ensuring energy is optimally utilized for air compression.
Cost Reduction
Permanent magnet frequency conversion technology reduces energy costs by over 35%, and the overall lifecycle cost of the compressor decreases by an average of 22%. Typically, the additional investment in the compressor is recouped within 1 to 2 years.
Stable Pressure
By utilizing the PID (Proportional, Integral, Differential) method, our compressor precisely adjusts to maintain stable system pressure, ensuring consistent and reliable performance.
Extended Lifespan
Frequency conversion startup minimizes impact on the power grid and machinery, significantly extending the compressor's service life.
