August’s New Generation of Permanent Magnet Air Compressors

August has launched the latest generation of permanent magnet variable frequency air compressor that is designed to solve all problems experienced in previous versions of air compressors. The new generation of August air compressors sets the standard for energy saving using sustainable advanced technology. Compared to the standard screw air compressor, the permanent magnet variable frequency air compressor has a higher energy-saving percentage and greater efficiency.

The latest version of August’s air compressor features high-efficiency permanent magnet synchronizing motor, also known as PM motor, which has a smaller volume and higher energy saving capacity. When installed together with special frequency converters, the new permanent magnet air compressor will provide even better energy saving effect than the usual inductive motor. Other additional benefits of this latest version of air compressor include low noise level while in operation, higher efficiency, and reliable performance.

To get a better understanding of the benefits provided by the latest generation of August’s permanent magnet variable frequency air compressor, let’s first look at the development path of air-cooled direct connection compressor technology.

 

The first generation of IP23 air cooled direct connection compressors

The initial air cooled direct connection compressors used an IP23 air cooled integrated shaft. The technology had several advantages. It was less expensive especially since the motor came with two fewer bearings. It had a cooling fan as well as a front and back motor cover. Its motor was smaller and it had a good cooling effect. More importantly, it had a transmission efficiency of 100%.

However, this first generation model came with a few disadvantages. For instance, it didn’t give you the ability to fully control the user’s environment. Another disadvantage was the motor rotor featured a strong magnet with a different asynchronous IP23 motor and was susceptible to main engine oil leakage. Maintaining it was often difficult and quite inconveniencing especially due to main engine oil leakage.

 

The second generation of IP54 air-cooled/oil cooled direct connection compressors

The second generation was integrated to an IP54 air cooled or oil cooled shaft. It had the main advantages of low running costs since its motor had two fewer bearings and featured a cooling fan and a front and back motor cover. It had 100% transmission efficiency, good cooling effect, a smaller motor, and could adapt easily to different user environments. However, it had a major disadvantage of main engine oil leakage which led to higher maintenance costs and inconveniences.

 

The latest generation of permanent magnet variable frequency air compressors

The latest version launched by August solves all the problems and disadvantages seen in the previous model. It has all the advantages of previous versions such as 100% transmission efficiency, better cooling effect, a smaller but energy-efficient motor, and is easy to adapt to the user’s environment. With a small bearing force, this latest generation of August air compressors has a reliable performance and a longer life. The

only disadvantage is that it costs higher than the former models. It also comes with more than two bearings and an independent fan. It nevertheless provides higher efficiency and better energy saving performance.
