The difference between permanent magnet variable frequency and ordinary screw air compressor

2022-06-22

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, energy-saving is different. The permanent magnet variable frequency air compressor adopts a 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.
