Working Principle
A permanent magnet frequency conversion air compressor employs cutting-edge pressure sensor technology to swiftly measure system pressure and air demand. This sophisticated detection mechanism, combined with precise control of the electric and frequency converter, adjusts motor speed while maintaining constant motor torque. It fine-tunes system pressure to deliver compressed air precisely when needed. If air consumption drops and the compressor's output exceeds system requirements, the inverter slows the motor, perfectly balancing production and consumption to uphold system stability. Conversely, when demand rises, the motor speed accelerates, guaranteeing a steady flow of compressed air.
Our compressor leverages state-of-the-art vector control technology to operate efficiently over a wide speed range, minimizing motor temperature rise and ensuring optimal torque for smooth operation. This advanced technology segregates motor current into torque-producing components and other current values, counteracting voltage drops at the motor's end. This sophisticated mechanism maximizes torque output without increasing current, thereby boosting operational efficiency.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Savings
Frequency conversion regulation significantly reduces the compressor's actual power consumption, ensuring energy is utilized optimally for air compression.
Cost Reduction
Permanent magnet frequency conversion technology slashes energy costs by over 35%, reducing the compressor's overall lifecycle cost by an average of 22%. Typically, the extra investment in the compressor is recouped within 1 to 2 years.
Stable Pressure
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 prolonging the compressor's service life.
Top Quality
Featuring top-quality imported bearings and the latest rotor profile designs with large rotors, substantial displacement, low speed, and minimal noise, our compressor enhances both efficiency and production quality.
