1. High power saving rate The variable frequency air compressor operates with variable frequency speed regulation, while the permanent magnet synchronous motor has good efficiency, high power factor, and a wide range of high efficiency. It can ensure extremely high operating efficiency in the entire speed regulation range, and the power saving rate is greatly improve.
2. Low noise The permanent magnet synchronous motor has low running noise. When the air compressor runs at a variable frequency and decelerates, the mechanical noise of the main engine is lower, and the cooling fan adopts variable frequency control, which further reduces the noise of the whole machine.
3. Air pressure stable permanent magnet variable frequency screw air compressor through fast and stable PID speed regulation function, real-time adjustment of motor speed according to actual air consumption, control of exhaust volume, to ensure stable air supply pressure without overshoot.
4. The smooth start-stop inverter adopts high-performance open-loop vector control, with large torque at low frequency and small starting current. It not only eliminates the impact on the power grid when starting, but also greatly reduces the mechanical loss.
