Working Principle
Our permanent magnet frequency conversion air compressor system incorporates cutting-edge pressure sensors that instantly detect the actual usage pressure and air consumption within the system. By employing precise electric and frequency converter controls, the system adjusts the motor speed while maintaining the motor's torque. This ensures the system pressure is regulated to perfectly match the required compressed air output. When air consumption drops, and the compressor's output surpasses the system's needs, the inverter air compressor lowers its speed, thus reducing the compressed air output. Conversely, it increases the motor speed to boost the compressed air supply, ensuring a stable system pressure at all times.
By embracing state-of-the-art vector control technology, our unit operates efficiently across a wide range of speeds, concurrently minimizing motor temperature rise. This guarantees optimal and sufficient torque for smooth air compressor operation. The motor current comprises the torque component and other current values dictated by vector control technology, ensuring the motor's current values are optimized. Notably, vector control techniques adeptly compensate for voltage drops at the motor's end, enabling maximum torque output without increasing current.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
With frequency conversion regulation, our system significantly reduces the actual power consumption, ensuring energy is efficiently utilized in air compression.
Cost Reduction
Thanks to permanent magnet frequency conversion technology, energy costs are slashed by over 35%, and compressor lifecycle costs are reduced by an average of 22%. The additional expense of the compressor is typically recouped within 1 to 2 years.
Steady Pressure
Utilizing the PID (proportional, differential, integral) method, our exclusive compressor is fine-tuned to maintain precise system pressure stability.
Extended Lifespan
The frequency conversion start mechanism mitigates the impact on the power grid and machinery, thereby extending the service life of the system.
Top Quality
Our compressors boast top-quality imported bearings and the latest rotor profile research. The large rotor, substantial displacement, low speed, and low noise collectively enhance efficiency and production quality.
