Revolutionary Working Principle
Our permanent magnet frequency conversion air compressor is engineered with precision, featuring a sophisticated pressure sensor that instantly detects real-time system pressure and air consumption. Utilizing precise electric and frequency converter control, it dynamically adjusts motor speed while maintaining constant torque. This ensures the system pressure is regulated for optimal output that perfectly aligns with demand. As system air consumption decreases, the compressor reduces rotational speed, thereby cutting down compressed air output. Conversely, it accelerates to increase air supply when demand rises, maintaining stable system pressure effortlessly.
Harnessing advanced vector control technology, our unit operates seamlessly across a wide range of speeds. This minimizes motor temperature rise while providing sufficient torque to drive the air compressor smoothly. The motor current, composed of torque and other vector control components, is optimized to determine the precise current values required. This technology adeptly compensates for voltage drops, enabling the motor to deliver maximum torque without increasing current, ensuring peak performance at all times.
