State-of-the-Art Working Principle
Our permanent magnet frequency conversion air compressor is engineered to perfection. It utilizes a sophisticated pressure sensor to instantly detect real-time system pressure and air consumption. By leveraging precise electric and frequency converter control, it dynamically adjusts motor speed while maintaining constant torque. This regulates system pressure, ensuring output aligns perfectly with demand. As system air consumption decreases, the compressor reduces rotational speed, cutting down compressed air output. Conversely, it accelerates to increase air supply when demand rises, ensuring stable system pressure effortlessly.
Harnessing cutting-edge vector control technology, our unit operates seamlessly across a wide range of speeds. This minimizes motor temperature rise while providing adequate 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, guaranteeing peak performance at all times.
