Innovative Working Principle
Our state-of-the-art permanent magnet frequency conversion air compressor is engineered with a sophisticated pressure sensor that instantaneously detects the actual system pressure and air consumption. Utilizing advanced electric and frequency converter controls, it adjusts the motor speed seamlessly without altering the torque, thereby regulating system pressure to deliver compressed air precisely as needed. When system air consumption diminishes, the compressor's output exceeds the requirement, prompting the inverter air compressor to reduce rotational speed and thus, the compressed air output. Conversely, if air consumption rises, the system increases motor speed to enhance compressed air production, ensuring a consistently stable system pressure.
Harnessing cutting-edge vector control technology, this unit operates efficiently across a wide speed spectrum while keeping motor temperature rise to a minimum. This ensures optimal torque generation for smooth air compressor operation. The motor current is precisely managed, with vector control technology adeptly distributing current to generate the necessary torque and other required current components. This sophisticated technique responds dynamically to voltage drops at the motor end, ensuring maximum torque output without increasing current, thus optimizing overall performance.
