permanent magnet frequency conversion screw air compressor

This permanent magnet frequency conversion screw air compressor delivers stable, precise air supply for major industries requiring tight control of compressed air. Its excellent energy efficiency, reliability, and intelligent adjustment capabilities make it an indispensable part of the modern production process.

Features of Permanent Magnet Frequency Conversion Screw Air Compressor

1. Air volume and pressure:
   • Delivers 5.0 m³/min air volume at 0.8 MPa—sufficient for a wide range of industrial applications.
   • Handles both long-term stable output and sudden load changes with continuous support.
2. Frequency conversion drive system:
   • Variable frequency mainframe and permanent magnet motor technology flexibly adjusts speed to match actual load.
   • Reduces energy waste from frequent starting and stopping, enhancing efficiency and stability.
3. High-efficiency screw compression:
   • Precision-designed screw tooth shape and small gap ensure efficient, low-loss compression and reduced power consumption.
4. Permanent magnet synchronous motor:
   • IPM motor features no slip, no electric excitation, and UH-grade magnetic steel for stability even in harsh conditions.
   • Ensures precise, reliable speed adjustment when paired with the inverter system.
5. No gear box, no belt transmission:
   • Embedded one-piece shaft connects motor and screw rotor directly—eliminating gear and belt losses for 100% transmission efficiency.
   • Results in a more compact structure and lower maintenance cost.
6. High efficiency and stable operation:
   • Wide (0–100%) speed adjustment range via vector control keeps the unit stable and efficient under all load conditions, extending equipment life.

Working Principle

1. Air intake and compression:
   Air enters via the suction port, is drawn in and compressed by the screw system, reaching the required pressure through optimized tooth and clearance design for high efficiency.
2. Frequency conversion speed control:
   The permanent magnet motor and variable frequency drive system adjust speed in real time to match air demand, minimizing energy waste and maximizing efficiency.
3. Stable, continuous output:
   The system ensures smooth adjustment and avoids waste from frequent start/stop cycles, maintaining stable air volume and pressure across the full 0–100% load range.
