Working Principle
Our state-of-the-art permanent magnet frequency conversion air compressor is engineered with a highly sensitive pressure sensor. This sensor instantly detects actual pressure and air consumption within your system. Through precise control, facilitated by an electric frequency converter, it dynamically adjusts the motor speed without modifying the torque, thereby regulating system pressure. This innovation ensures that compressed air is delivered exactly as needed. When air demand wanes, the system smartly reduces motor speed to lower compressed air output, maintaining energy efficiency. Conversely, a surge in air consumption prompts an increase in motor speed, thereby stabilizing system pressure consistently.
By adopting cutting-edge vector control technology, our unit runs efficiently across an extensive range of speeds. This minimizes motor temperature rise and ensures optimal torque for flawless operation. The motor current is divided into torque and other components, which are precisely managed by vector control methods. These methods adeptly respond to voltage drops at the motor end, maximizing torque output without increasing current. This approach protects your machinery and guarantees peak performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
