FG-AMB turbo blower parameter

FG-AMB won several patent like: the US patent, Korea patents etc. The company also has the ISO9001 certification and CE. Now the turbo blower has passed the test of the mechanical industrial blower product quality supervision, fluid efficiency reaches 82.99%, to compare with traditional blower the efficiency improved by 15~40%. Otherwise, AMB turbo blower’s stability is better than air blower, because it will produce friction between the rotatable shaft with the surrounding bearings when the machine turn on or turn off. When the air blower in runtime, the rotational accuracy is 10μm, there are no fitting device in the market suitable for such a small gap. It will cause damage to the blower when the impurities came in.

The rotational accuracy of AMB turbo blower is 500μm, it can solve this fitting difficult problem. Currently, the FLC10008 turbo blower has been put into use in Korea POSCO in June 2014 and Foshan Yanbu sewage water treatment plant in October 2015.

A strong R&D team

In the conference, every participants were looking forward to this new product. They have the problems on the performance, technology advantages, maintenance, special product development of the turbo blower. Dr. Choi Sang Hyun of FG-AMB answered these questions one by one, in the same time participants can learned more about the company's Korean technology background. Design and develop the magnetic bearing system should use the mechanical design, testing technology, DSP control technology, electromagnetic design technology and other core technology, that require an integrated multi-disciplinary and experienced R & D team. Actually, there are few company can own such a R&D team in the world. FG-AMB has such a strong independent Korea R&D team which have wealthy research and development experience on active magnetic bearing, rotating machinery design, manufacturing systems, control systems and other disciplines. Dr. Choi Sang Hyun is the leader of this team, he professional in the rotor dynamics, mechanical. He uses to be the special researcher of Seoul National University turbine power machinery research center, and the special scholars engaged in research work in Germany. He engaged in design and research work in the world’s famous rotating machinery companies like: ABB, Atlas Copco etc. Dr. Choi has been engaged in the research work on rotating machinery and magnetic bearing system during 10 years working for the D&M Technology Ltd. which is a famous magnetic bearing company in Korea.

The company mastered the core technology magnetic bearings, not only successfully be applied in the development of AMB turbo blower, but also done a lot of research and development in various fields like: semiconductor industry; Mag-lev system for R2R processing in printed electronic industry; ORC turbine in energy industry; High-speed motor of NUAA; Milling motorized spindle system of HUST; Turbo molecular pump of JE-IL Vacuum; Nano-spindle of POSCO; Refrigerant compressor of Samsung; High-speed switched reluctance motor etc.
