Background
The use of the permanent magnet variable frequency air compressor is a major breakthrough of the energy-saving air compressor technology, and compared with a common screw air compressor, the permanent magnet variable frequency air compressor has very obvious advantages in the aspects of service life, skill and maintenance cost of the machine. The high-performance neodymium iron boron magnet is a core material of a motor of the variable frequency air compressor. The permanent magnet frequency conversion compressor can be started smoothly by a controller or a PID regulator inside the frequency converter due to the fact that the variable-frequency screw air compressor utilizes the stepless speed regulation characteristic of the frequency converter; and the gas consumption fluctuation is large, and the response can be quickly adjusted.
