Working Principle
A permanent magnet frequency conversion air compressor leverages an advanced pressure sensor to instantly detect the actual pressure and air consumption in the system. Through the precise control facilitated by the electric and frequency converter, it adjusts the motor speed without altering the torque of the air compressor motor. This regulation ensures the output of compressed air is aligned with demand. When system air consumption drops, the compressor's output surpasses the need, prompting the inverter air compressor to slow down the motor, thereby decreasing compressed air output. Conversely, when air consumption increases, the motor speed accelerates, augmenting the compressed air output to sustain stable system pressure.
Utilizing cutting-edge vector control technology, this compressor unit is capable of operating across a wide range of speeds while ensuring minimal motor temperature rise. This technology guarantees the motor delivers the necessary torque to drive the air compressor seamlessly. The motor current, consisting of the torque component generated by the motor, is efficiently distributed by vector control technology. This allows optimal compensation for voltage drops at the motor end, enabling maximum torque output without increasing current usage.
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. This results in impressive energy efficiency and notable cost savings.
Cost Reducing
The innovative permanent magnet frequency conversion technology slashes energy costs by over 35%, while reducing the compressor's life cycle cost by an average of 22%. The additional investment in this advanced compressor can be recouped within 1 to 2 years, making it a smart, economical choice.
Steady Pressure
Employing the PID (proportional, differential, integral) method, this advanced compressor ensures precise adjustment to maintain stable system pressure, enhancing overall operational reliability.
Life Extension
Frequency conversion starts dramatically reduce the impact on power grids and machinery, significantly prolonging the service life of the equipment. This results in less downtime and lower maintenance costs.
Top Quality
Crafted with the finest imported bearings and the latest rotor profile research, this compressor features a large rotor, substantial displacement, low speed, and low noise. These attributes collectively enhance efficiency and elevate production quality, delivering superior performance every time.
