Working Principle
Our state-of-the-art permanent magnet frequency conversion air compressor employs an ultra-sensitive pressure sensor to instantly gauge the actual pressure and air usage within your system. By employing precise control through an electric frequency converter, it dynamically adjusts motor speed without changing torque, thus maintaining system pressure. This ensures that compressed air is supplied exactly according to demand. When air consumption drops, the system intelligently decreases motor speed, reducing compressed air output and boosting efficiency. Conversely, a rise in air consumption prompts an increase in motor speed, ensuring stable system pressure at all times.
By leveraging advanced vector control technology, our unit operates efficiently across a broad spectrum of speeds, minimizing motor temperature rise and ensuring optimal torque for smooth operation. The motor current, divided into torque and additional components, is masterfully managed by vector control techniques. These techniques respond intelligently to voltage drops at the motor end, maximizing torque output without increasing current, thus safeguarding your equipment and ensuring peak performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
