Product Structure

 

Working Principle

A permanent magnet frequency conversion air compressor epitomizes engineering excellence. It features a highly responsive pressure sensor that meticulously monitors real-time system pressure and air demand. With seamless integration of electric and frequency converter controls, the motor speed is adeptly adjusted without altering torque, ensuring constant system pressure. This intelligent regulation ensures that compressed air is perfectly aligned with demand. As air consumption decreases, the compressor output exceeds requirements, prompting the advanced inverter to reduce motor speed gracefully, thus decreasing compressed air output. Conversely, by elegantly accelerating the motor, the system increases compressed air supply to stabilize pressure, maintaining perfect harmony within the system.

Leveraging state-of-the-art vector control technology, these units operate with unparalleled precision across a broad speed range. This results in minimal motor temperature rise, creating a seamless synergy that offers optimal torque for smooth air compressor operation. By intelligently disaggregating motor current into torque and auxiliary components, vector control ensures optimal current distribution, delivering maximum torque output even during voltage drops at the motor's end while maintaining steady current levels. This smart adaptability ensures peak motor performance, guaranteeing that your system operates at peak efficiency.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor

High Efficiency and Energy Saving
With innovative frequency conversion regulation, power consumption is precisely aligned with operational demands, optimizing energy use in air compression. This maximizes every watt for efficiency, making operations both economical and environmentally conscious, adhering to industry-leading energy-saving standards.

Cost Reduction
