Adopts IE5 ultra-high energy efficiency permanent magnet variable frequency motor, and permanent magnets are used to provide excitation without excitation current and excitation loss, which provides the efficiency and power density of the motor.
The inverted umbrella aerator directly driven by the permanent magnet motor has incomparable advantages in the application of sewage treatment engineering.
The frequency converter screw air compressor adopts the stepless variable speed characteristic of the frequency converter and realizes a smooth start through the internal controller or PID regulator.
The permanent magnet synchronous motor also uses frequency conversion technology to realize the soft speed regulation of the motor, and can automatically adjust the motor speed according to the actual demand of the load to achieve the purpose of energy-saving.
The high-efficiency permanent magnet variable frequency motor is the best choice for a screw air compressor drive motor. It is more efficient and energy-saving than an ordinary three-phase asynchronous variable frequency motor!
First, the service life is different. From the perspective of machine service life, permanent magnet variable frequency screw air compressors are better. Due to the inverter drive, the air compressor adopts a soft start when starting, which has a certain protective effect on the motor and reduces the possibility of burning the motor. Second, the energy saving is different. The permanent magnet variable frequency air compressor adopts high-efficiency rare earth permanent magnet motor and frequency converter. These two parts are of great help to the energy saving of the air compressor. Third, maintenance costs also vary. From a maintenance cost perspective, the magneto bearings are greased to eliminate failure points and reduce maintenance costs.
