Sophisticated Working Principle
Our permanent magnet frequency conversion air compressor is a marvel of engineering precision. It features an advanced pressure sensor that detects system pressure and air consumption in real-time. With its precise electric and frequency converter control, the compressor dynamically adjusts motor speed while maintaining constant torque. This ensures the system pressure is regulated, aligning output perfectly with demand. As air consumption decreases, the compressor slows down to reduce compressed air output. When demand rises, it speeds up to increase air supply, maintaining stable system pressure with ease and efficiency.
By employing cutting-edge vector control technology, our system operates effortlessly across various speeds, minimizing motor temperature rise while ensuring adequate torque to drive the air compressor smoothly. The motor current, composed of torque and other vector control components, is meticulously optimized to determine precise current values. This technology compensates for voltage drops adeptly, allowing the motor to deliver maximum torque without increasing current, guaranteeing peak performance at all times.
