Working Principle
A permanent magnet frequency conversion air compressor is engineered to detect the system's real-time pressure and air consumption via a pressure sensor. Through precise electric and frequency converter controls, it adjusts the motor speed while keeping the air compressor motor's torque unchanged. This regulation ensures the output of compressed air aligns perfectly with demand. When the system's air consumption drops and exceeds the air provided by the compressor, the inverter air compressor reduces its rotational speed, decreasing the amount of compressed air output. Conversely, it increases the motor speed to boost compressed air output, maintaining stable system pressure.
Employing cutting-edge vector control technology, our unit operates efficiently over a wide speed range. This ensures minimal motor temperature rise while delivering adequate and optimal torque to drive the air compressor seamlessly. The motor's current, comprising the torque component and additional vector-controlled elements, is meticulously balanced. Vector control techniques adeptly compensate for voltage drops at the motor end, enabling maximum torque output without increasing current.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
Frequency conversion regulation can significantly reduce the actual power consumption of the compressor, aligning energy usage with air compression needs.
Cost Reducing
With permanent magnet frequency conversion technology, energy costs are slashed by over 35%. The compressor's life cycle cost drops by an average of 22%, with initial extra costs recouped within 1 to 2 years.
Steady Pressure
Through the sophisticated PID (proportional, differential, integral) method, this compressor ensures precise adjustments for stable system pressure.
Life Extension
Frequency conversion starts help mitigate the impact on the power grid and machinery, thereby extending the service life of the compressor.
Top Quality
Utilizing premium imported bearings and the latest rotor profile developments, this compressor features a large rotor, significant displacement, low speed, and low noise, enhancing efficiency and product quality.
