Working Principle
Harnessing the latest advancements, our permanent magnet frequency conversion air compressor instantly gauges system pressure and air demand using an advanced pressure sensor. This intelligent detection, paired with precise electric and frequency converter control, modulates motor speed without affecting torque. As a result, system pressure is carefully adjusted to supply compressed air on demand. When air consumption drops and compressor output exceeds system needs, the inverter reduces rotational speed, perfectly synchronizing production with consumption to sustain system equilibrium. Conversely, when demand increases, motor speed rises to ensure a consistent stream of compressed air.
Our compressor leverages cutting-edge vector control technology, operating efficiently across a wide speed spectrum while minimizing motor temperature rise and ensuring optimal torque. Vector control technology divides motor current into torque-generating components and other current values, compensating for 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 harnessed for air compression.
Cost Reduction
Our permanent magnet frequency conversion technology cuts energy costs by over 35%, reducing the overall lifecycle cost of the compressor by an average of 22%. Typically, the additional investment in the compressor is recovered within 1 to 2 years.
Stable Pressure
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 extending the compressor's service life.
