Working Principle
Experience the pinnacle of innovation with our permanent magnet frequency conversion air compressor, equipped with an ultra-sensitive pressure sensor that instantly reads the real-time pressure and air demand of your system. The electric frequency converter precisely adjusts motor speed, ensuring that torque remains consistent, which results in a stable system pressure. This technological marvel allows compressed air supply to perfectly meet your actual needs. Should there be a reduction in air consumption, the system intelligently decreases motor speed to lower compressed air output, optimizing energy efficiency. Conversely, when air consumption rises, it automatically increases motor speed to maintain unwavering system pressure, ensuring reliability at all times.
Empowered by sophisticated vector control technology, our compressors exhibit outstanding efficiency across a broad range of speeds. This effectively minimizes motor temperature rise while guaranteeing optimal torque for smooth and flawless operation. The motor current is expertly split into torque and additional components, with advanced vector control techniques deftly managing these. These techniques intelligently compensate for voltage drops at the motor's end, optimizing torque output while keeping current levels low, thus protecting your equipment and maintaining exceptional performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
