Working Principle
Our state-of-the-art permanent magnet frequency conversion air compressor incorporates an ultra-sensitive pressure sensor to instantly gauge actual pressure and air consumption within your system. By utilizing an electric frequency converter, it meticulously modulates the motor speed without altering the torque, thereby controlling the system pressure with precision. This ensures that compressed air delivery is harmonized with real-time demand. When air consumption drops, the system intelligently decreases motor speed, optimizing compressed air output to maintain impeccable efficiency. Conversely, an uptick in air consumption prompts an increase in motor speed, ensuring unwavering system pressure at all times.
Our unit harnesses advanced vector control technology to operate efficiently across a broad spectrum of speeds, thereby minimizing motor temperature rise and ensuring optimal torque for seamless operation. By meticulously managing the motor current, divided into torque and other components, vector control techniques deftly respond to voltage drops at the motor end. This maximizes torque output without increasing current, thereby safeguarding your equipment and ensuring peak performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
