Working Principle
Our cutting-edge permanent magnet frequency conversion air compressor is meticulously crafted with an ultra-sensitive pressure sensor, ensuring precise measurements of actual pressure and air usage within your system. This state-of-the-art equipment boasts a refined electric frequency converter, which expertly adjusts motor speed while maintaining torque, thereby ensuring a consistent system pressure. By delivering compressed air precisely as needed, the system intuitively adapts to variations in air consumption. When demand decreases, the motor speed gracefully decelerates, reducing compressed air output and boosting efficiency. Conversely, an increase in air demand prompts the motor speed to elegantly adjust, ensuring stable system pressure is consistently maintained.
Unleashing the power of advanced vector control technology, our compressor operates with exceptional efficiency across a broad spectrum of speeds, minimizing motor temperature elevation and delivering sublime torque for seamless operations. With motor current expertly divided into torque and auxiliary components, vector control techniques ingeniously manage them, responding adeptly to voltage drops at the motor end. This maximizes torque output without increasing current, safeguarding your equipment and delivering unparalleled performance.
