Cutting-Edge Working Principle
Our state-of-the-art permanent magnet frequency conversion air compressor integrates a highly sensitive pressure sensor that instantaneously detects the precise pressure and air consumption within your system. By employing an electric frequency converter, it meticulously adjusts the motor speed without altering the torque, thereby dynamically regulating the system pressure. This sophisticated mechanism ensures that compressed air is delivered exactly as required. When air consumption decreases, the system intelligently reduces motor speed to minimize compressed air output, thereby maintaining optimal efficiency. Conversely, an increase in air consumption triggers an elevation in motor speed, ensuring consistent and stable system pressure at all times.
Employing advanced vector control technology, our unit operates with unparalleled efficiency across a diverse range of speeds, significantly reducing motor temperature rise and ensuring optimal torque for flawless performance. The motor current, categorized into torque and ancillary components, is expertly managed by vector control techniques. These techniques intuitively respond to voltage drops at the motor end, maximizing torque output without increasing current, thereby safeguarding your equipment and guaranteeing peak performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
Unmatched High Efficiency and Energy Saving
Our cutting-edge frequency conversion regulation technology significantly curtails actual power consumption, channeling energy effectively into air compression. This leads to extraordinary energy savings while enhancing overall system efficiency.
