Product Structure

Working Principle

The permanent magnet frequency conversion air compressor is a marvel of engineering, designed to dynamically adapt to the system's real-time pressure needs. Equipped with a sophisticated pressure sensor, it accurately detects system pressure and air consumption, adjusting the motor speed seamlessly through precise electric and frequency converter control. This innovative approach ensures that the torque of the air compressor motor remains constant, allowing the system pressure to be regulated precisely to meet the demand for compressed air. When air consumption diminishes, the compressor intelligently decreases its rotational speed, thus reducing the air output to align with the system's needs. Conversely, when more air is required, the motor speed increases to ensure a stable and consistent system pressure.

Vector control technology is at the core of this advanced unit, allowing it to operate across a broad spectrum of speeds while keeping motor temperature rise to a bare minimum. This ensures that the motor has adequate and sufficient torque to drive the air compressor effortlessly. The motor current is smartly divided into components responsible for generating torque and other operational requirements, thanks to the state-of-the-art vector control technology. This system adeptly compensates for any voltage drops at the motor end, enabling the motor to deliver maximum torque output without a surge in current, thereby enhancing efficiency and performance.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
