Working Principle
A permanent magnet frequency conversion air compressor harnesses an advanced pressure sensor to instantly gauge system pressure and air demand. This intelligent detection, combined with precise control of the electric and frequency converter, modulates motor speed without affecting motor torque. Thus, it fine-tunes system pressure to supply compressed air precisely on demand. When air consumption diminishes and the compressor output exceeds system needs, the inverter reduces rotational speed, perfectly syncing production with consumption to sustain system equilibrium. Conversely, when demand rises, the motor speed increases to ensure a consistent and steady stream of compressed air.
Utilizing cutting-edge vector control technology, our compressor operates efficiently across a wide speed spectrum while curbing motor temperature rise, ensuring optimal torque for smooth functioning. Vector control technology splits motor current into torque-producing components and other current values, compensating for voltage drops at the motor end. This sophisticated mechanism maximizes torque output without elevating current, thereby significantly boosting operational efficiency.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Savings
Frequency conversion regulation dramatically reduces the actual power consumption of the compressor, ensuring energy is optimally harnessed for air compression.
Cost Reduction
Permanent magnet frequency conversion technology cuts energy costs by over 35%, and the overall lifecycle cost of the compressor is slashed by an average of 22%. Typically, the additional investment in the compressor is recovered within 1 to 2 years.
Stable Pressure
By employing 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 mitigates impact on the power grid and machinery, significantly prolonging the compressor's service life.
Top Quality
Featuring superior imported bearings and the latest rotor profile designs-large rotors, substantial displacement, low speed, and minimal noise-our compressor enhances both efficiency and production quality.
