Permanent magnet variable frequency air compressor features introduced

As a new generation of compressed air supply equipment, permanent magnet variable frequency air compressor combines permanent magnet motor and variable frequency technology, which has significant technical advantages and economic value. The following is its core characteristics analysis:

1. Power Innovation: Permanent Magnet Synchronous Motor

• high efficiency and energy saving
  using rare earth permanent magnet materials, the magnetic field strength is constant, no external excitation is required, and the no-load current is reduced by 40%-60%. Compared with traditional air compressors, energy efficiency is improved by 10%-15%, and long-term operating costs are reduced by more than 30%.

• high power density
  the motor volume is reduced by 30% and the weight is reduced by 25%, which is convenient for the compact design of the equipment and adapts to the installation environment with limited space.

2. intelligent control: variable frequency drive technology

• accurate supply and demand matching
  through the pressure sensor and PID algorithm, the stepless adjustment of the speed in the range of 20%-100% is realized. When the gas consumption is reduced, the speed will be automatically reduced to avoid the waste of energy consumption of "loading-unloading.

• Pressure stability improvement
  the output pressure fluctuation is controlled within ± 0.01MPa to ensure the stable operation of pneumatic tools and prolong the service life of equipment.

3. operation and maintenance advantages

• low noise design
  the permanent magnet motor has no brush friction, the frequency conversion control reduces the impact of start and stop, the noise is reduced by 5-10 decibels (normal working condition ≤ 75dB), and the working environment is improved.

• Extend equipment life
  soft start technology makes the starting current less than or equal to 1.2 times the rated value, reducing mechanical impact. Oil-free models eliminate oil pollution and extend the maintenance period to 20000 hours.

4. economy and environmental protection

• significant energy saving benefits
  under 50% load rate, it can save 40%-50% of electricity compared with power frequency air compressor. Taking the 100kW model as an example, 5000 hours of annual operation can save 200000 degrees of electricity and reduce carbon emissions by about 200 tons.

• Policy Adaptability
  meet the first level of energy efficiency standards, help enterprises to obtain green factory certification, enjoy energy-saving subsidy policy.

5. intelligent management

• remote monitoring
  support Internet of Things access, real-time view of operating status, energy consumption data, to achieve predictive maintenance.

• multi-machine joint control
  multiple devices can be networked to run, according to the amount of gas automatically allocated load, further improve energy efficiency.

Typical application scenarios

• precision Manufacturing production of electronic components, stabilized gas supply for laser cutting equipment.
• Medicine Food oil-free air compressor to ensure clean room environment, in line with GMP certification requirements.
• energy saving transformation: Replace the old frequency equipment, quickly achieve cost reduction and efficiency.

Through the synergy of permanent magnet motor and frequency conversion technology, permanent magnet frequency conversion air compressor redefines the efficiency standard of compressed air system and becomes the ideal choice for green intelligent factory in the era of industrial 4.0.
