Working Principle
Discover the brilliance of our state-of-the-art permanent magnet frequency conversion air compressor, a marvel of engineering excellence. Expertly designed, it features an ultra-sensitive pressure sensor that accurately gauges the actual pressure and air usage within your system. By employing an electric frequency converter, it precisely adjusts motor speed while maintaining torque, ensuring a reliable and consistent system pressure. This results in the delivery of compressed air finely calibrated to align with your needs. As air consumption decreases, the system gracefully reduces motor speed, thus minimizing compressed air output and optimizing efficiency. In contrast, an increase in air consumption triggers a smooth increase in motor speed, sustaining a stable system pressure effortlessly and continuously.
Our compressors, driven by sophisticated vector control technology, boast extraordinary efficiency across a wide range of speeds. This advanced technology curtails motor temperature rise and guarantees impeccable torque for seamless operation. By skilfully partitioning motor current into torque and auxiliary components, these cutting-edge vector control techniques adeptly respond to voltage drops at the motor's terminal, maximizing torque output without any escalation in current. This not only preserves your equipment but also promises unparalleled performance and reliability.
