Working Principle
A Permanent Magnet Frequency Conversion Air Compressor integrates a pressure sensor that instantly detects the actual system pressure and air consumption. Through precise control of the electric and frequency converter, the motor speed is adjusted without altering the torque of the air compressor motor. This regulation allows the compressor to provide compressed air as needed. When air consumption decreases, the motor's rotational speed is reduced to lower the output of compressed air; conversely, it increases the motor speed when demand rises, ensuring a stable system pressure.
Utilizing advanced vector control technology, our unit operates across a broad range of speeds while minimizing motor temperature rise, ensuring efficient and sufficient torque to drive the air compressor smoothly. The motor current, consisting of torque components and other vector control current values, is optimally managed to compensate for voltage drops at the motor end. This results in maximum torque output without increasing the current, thereby enhancing overall performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
Frequency conversion regulation significantly reduces the actual power consumption of the compressor, ensuring energy is effectively utilized for air compression, thereby enhancing efficiency.
Cost Reducing
Our Permanent Magnet Frequency Conversion Technology slashes energy costs by over 35%, and the compressor's life cycle cost is reduced by an average of 22%. The additional investment in the compressor is typically recovered within 1 to 2 years, making it a cost-effective choice.
Steady Pressure
Employing the PID (Proportional, Differential, Integral) method, our exclusive compressor accurately adjusts to maintain stable system pressure, ensuring consistent performance.
Life Extension
The frequency conversion start reduces the impact on the power grid and mechanical components, thereby prolonging the service life of the compressor.
Top Quality
Our compressor features top-quality imported bearings and the latest rotor profile design. The large rotor, with its substantial displacement at low speed and low noise, significantly improves efficiency and production quality.
