Product Structure

Working Principle

This groundbreaking permanent magnet frequency conversion air compressor harnesses a pressure sensor to immediately detect the actual pressure and air consumption within the system. By employing precision electric and frequency converter controls, it adjusts motor speed seamlessly without altering the torque, thereby modulating system pressure. This innovative design ensures compressed air is delivered precisely as needed. In scenarios where air consumption drops and exceeds system requirements, the inverter air compressor ingeniously slows down to minimize compressed air output. Conversely, it accelerates the motor speed to boost compressed air availability, maintaining an unwaveringly stable system pressure.

Harnessing cutting-edge vector control technology, this unit is engineered to operate across an extensive speed range, ensuring minimal motor temperature rise. This results in acquiring the ideal torque necessary to drive the air compressor with exceptional smoothness. The motor current is comprised of torque components and other vector control technology, which strategically allocates current values to determine motor current components that generate torque and others. This advanced approach optimally compensates for voltage drops at the motor's end, enabling the motor to unleash maximum torque without escalating current usage.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor

High efficiency and energy saving
Through frequency conversion regulation, actual power consumption of the compressor is significantly reduced. This refined technique ensures that energy is maximally utilized in air compression, paving the way for enhanced efficiency.

Cost Reducing
Embracing permanent magnet frequency conversion technology revolutionizes energy costs, slashing them by over 35%. Additionally, the life cycle cost of compressors diminishes by an average of 22%, with the supplementary compressor cost recouped within a swift 1 to 2 years.

Steady Pressure
Employing the sophisticated PID (proportional, differential, integral) method, this exclusive compressor is meticulously adjusted to sustain system pressure stability with pinpoint accuracy.

Life Extension
The initiation of frequency conversion mitigates the impact on power grids and machinery, thereby extending the service life of the compressor substantially.

Top quality
Incorporating top-tier imported bearings and pioneering rotor profile development, this compressor boasts a large rotor, significant displacement, low speed, and low noise. These attributes collectively elevate efficiency and production quality to unparalleled heights.
