Revolutionary Working Principle
Our permanent magnet frequency conversion air compressor epitomizes engineering excellence. Utilizing an advanced pressure sensor, it swiftly detects real-time system pressure and air consumption. Through precise electric and frequency converter control, it dynamically adjusts motor speed while maintaining constant torque. This ensures the system pressure is meticulously regulated, with output perfectly matching demand. As system air consumption diminishes, the compressor decelerates, reducing compressed air output. Conversely, it accelerates to boost air supply when demand surges, effortlessly maintaining stable system pressure.
Employing state-of-the-art vector control technology, our unit performs flawlessly across a broad speed spectrum. This minimizes motor temperature rise while delivering sufficient torque to propel the air compressor smoothly. The motor current, integrating torque and other vector control components, is optimized to ascertain the precise current values needed. This sophisticated technology compensates for voltage drops adeptly, enabling the motor to achieve maximum torque without increasing current, ensuring peak performance consistently.
