Working Principle
Our state-of-the-art permanent magnet frequency conversion air compressor utilizes a highly sensitive pressure sensor to instantly detect the actual pressure and air consumption within your system. Through meticulous control via an electric frequency converter, it dynamically adjusts the motor speed without altering the torque, thus regulating the system pressure. This ensures that compressed air is provided precisely according to demand. When air consumption decreases, the system intelligently lowers the motor speed to reduce compressed air output, maintaining efficiency. Conversely, an increase in air consumption triggers a rise in motor speed, ensuring a stable system pressure at all times.
By adopting advanced vector control technology, our unit operates efficiently across a wide range of speeds, minimizing motor temperature rise and ensuring optimal torque for seamless operation. The motor current, divided into torque and other components, is meticulously managed by vector control techniques. These techniques intelligently respond to voltage drops at the motor end, maximizing torque output without increasing current, thus protecting your equipment and ensuring peak performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
Our frequency conversion regulation technology significantly reduces actual power consumption, applying energy effectively to air compression. This results in remarkable energy savings and enhances overall system efficiency.
Cost Reducing
Experience a reduction in energy costs by over 35% with our permanent magnet frequency conversion technology. The life cycle cost of compressors is reduced by an average of 22%, allowing the extra cost of the compressor to be recovered within just 1 to 2 years.
Steady Pressure
Utilizing the sophisticated PID (proportional, differential, integral) method, our compressors are finely tuned to maintain consistent system pressure, ensuring continuous operational stability and reliability.
Life Extension
