Product Structure

Working Principle

A permanent magnet frequency conversion air compressor employs an innovative pressure sensor that immediately detects the actual pressure and air consumption within the system. Through precise control of the electric and frequency converter, it dynamically adjusts the motor speed, maintaining the motor torque unchanged. This allows the system pressure to be modulated, delivering compressed air precisely as needed. When air consumption in the system decreases, the compressor produces more air than required, prompting the inverter air compressor to slow down, reducing output; conversely, it accelerates the motor speed when more air is needed, ensuring stable system pressure. This ensures seamless operation and efficiency in air compression.

By employing advanced vector control technology, the unit operates efficiently across a wide range of speeds while minimizing motor temperature rise. This ensures optimal torque for smooth air compressor operation. The motor current is intelligently composed of the torque component and other auxiliary currents, distributed by vector control technology to maintain optimal torque without increasing current. These techniques adeptly compensate for voltage drops at the motor end, allowing the motor to deliver maximum torque seamlessly and efficiently.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor

High Efficiency and Energy Saving
The frequency conversion regulation remarkably reduces the actual power consumption of the compressor in direct proportion to its usage. This ensures energy is effectively harnessed for air compression, leading to significant energy savings.

Cost Reducing
The innovative permanent magnet frequency conversion technology slashes energy costs by over 35%, while the compressor's lifetime costs are curbed by an average of 22%. The initial investment is swiftly recouped within just 1 to 2 years, making it a wise financial choice.

Steady Pressure
Utilizing the precise PID (Proportional, Integral, Differential) method, the exclusive compressor is meticulously tuned to maintain consistent system pressure, ensuring optimal and stable performance.

Life Extension
The frequency conversion start-up diminishes the impact on both the power grid and the machinery, significantly extending the service life of the compressor and enhancing its reliability.

Top Quality
Incorporating top-quality imported bearings and the latest innovations in rotor profile, the compressor boasts a large rotor with substantial displacement, operating at low speed and noise levels. This boosts efficiency and elevates production quality, marking it as a superior choice in the industry.
