Advantages of permanent magnet motor

Air compressors generally do not work at full load, and the industry statistical load rate (load time / total running time) averages 60%. When no load occurs, the motor must continue to run at no load. The no-load motor still consumes 33-40% of the electricity bill. This part of the energy loss will be huge, and the application of frequency conversion technology will save this part of the energy, the benefits are very significant.

The frequency control technology with vector control technology as the core can automatically adjust the exhaust volume according to the actual demand of compressed air, so that the no-load energy consumption can be eliminated, the energy saving effect is remarkable, and the variable flow control makes the gas supply stable. And the soft start is implemented. The starting current is large within 1.2 times of the rated current. Compared with the power frequency starting, which is generally more than 6 times of the rated current, the starting impact force is small, and the impact on the entire mechanical system is greatly reduced.

Rotor:

 

Rotors are asymmetric in profile, backed up by ball bearings and roller bearings. Operates at a low speed, thereby low in abrasion and maintenance expenses, air end is long service life. Helical gears can produce axial force to kill some acting force, which reduces the load of the bearing of air end.

 

Control panel:

 

Intelligent microcomputer-based control technology can monitor and control in all aspects the complete machine following your instructions, remote control realizes unattended operation, and the user-friendly human-machine interface displays instructions and parameters in written form also, it can function to self diagnose faults, give warning and automatically regulate the capacity.


Oil filter:


Rotary filters are applied to completely remove the impurities in the lubricating oil, easy to replace and free of oil impregnate.


Cooler:


It is designed for low temperature difference to increase heat exchange area, and ideal to be applied to high-humidity operating environment.


Excellent quality of motors:

Compared to normal motors, Servo motors have smaller dimensions and more excellent energy saving.It will exert incomparable energy saving effect than normal inductive motor when installed with the special frequency convectors.


The host machine of compressor is of high efficiency and long life:


The quality of host machine of permanent magnet synchronizing variable frequency compressor is excellent. The advanced molded lines ensure the minimum specific power.It is designed in the FEM strength analysis.to ensure the stability and reliable of each part,and to realize long term operation with no faults,low noise and long life.
