Working Principle
Our cutting-edge permanent magnet frequency conversion air compressor is crafted with an ultra-sensitive pressure sensor that meticulously gauges the actual pressure and air usage in your system. With unparalleled precision control via an electric frequency converter, it exquisitely calibrates motor speed while preserving torque, ensuring a consistent system pressure. This ensures compressed air is delivered flawlessly according to demand. When air consumption diminishes, the system intelligently reduces the motor speed, thereby minimizing compressed air output and maximizing efficiency. Conversely, when there's an increase in air consumption, the motor speed gracefully escalates, maintaining an unwavering system pressure at all times.
Harnessing the power of advanced vector control technology, our compressor operates with extraordinary efficiency over a vast speed range, minimizing motor temperature rise while ensuring exquisite torque for seamless operation. The motor current, divided into torque and auxiliary components, is expertly governed by vector control techniques. These techniques adeptly respond to voltage drops at the motor end, maximizing torque output without increasing current, thereby safeguarding your equipment and ensuring unparalleled performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
